On the contrary, it is intended that the scope be limited by the claims appended hereto. II. Overview

[0037] As described in further detail below, aspects of the present disclosure relate to improved cryogenic milling systems, apparatus, and methods. The cryogenic milling system includes a body and a sample holding vessel having one or more blades therein. After the sample is placed in the sample holding vessel and the vessel is placed in the body, a cryogen is supplied to the vessel to remove heat from the sample. The blades in the vessel are rotated, which causes the sample to be reduced to a size suitable for further analysis. Detailed examples of the disclosed systems, apparatus, and methods are provided below. III. Detailed Examples

[0038] Figure 1 to Figure 2 A perspective view of an example cryogenic grinding system 50 having an example body 100 configured to removably receive a sample-holding vessel 200 is illustrated. Figure 1B One example of a cryogenic grinding system is shown in which a sample holding vessel 200 is placed within the opening 101 of the body 100 . Figure 2 An example of the cryogenic grinding system 50 is shown with the sample holding vessel 200 removed from the opening 101 of the body 100 .

[0039] Figure 1B 2 is a partial view of a sample holding vessel 200 with portions of an outer wall (e.g., wall 202) removed to illustrate an example blade configuration 204 inside the vessel 200. Figure 1B Two blades are shown, but it is noted that the container 200 can instead have a single blade (e.g., as described below with respect to Figure 4B 10). In another example, the vessel may instead have more than two blades (e.g., 3 blades, 4 blades, 5 blades) in another example configuration. The holding vessel 200 may be received into the body 100, for example, via a series of tracks 112a and 112b configured to slidably receive the guide rails 210a and 210b of the sample holding vessel 200. Once the sample holding vessel 200 is Figure 1A , the engagement rod 110 can be rotated (e.g., Figure 1A ), thereby causing the receiving vessel 200 to engage with the opening 101 of the body 100 or otherwise be retained in the opening 101 of the body 100. In one example, rotating the engagement rod 110 in the direction F may cause one or more pressing members (described in further detail below) to press upward in the direction F (see Figure 1A ), the pressing member can press upward, thereby pressing the guide rails 210a and 210b against the top of each corresponding track 112a and 112b of the main body 100 and applying a clamping force to the sample holding vessel 200.

[0040] As described in further detail below, once the user slides the sample holding vessel 200 into the opening 101 of the body 100, and the engagement rod 110 is rotated in the direction F, various connectors (e.g., cryogen source connectors, exhaust connectors, and / or temperature sensors or sensor electrical contacts) and / or blade drive source connectors can be engaged so that the sample contained in the sample holding vessel 200 can be further processed by the cryogenic grinding system 50. The body 100 can also include a display interface 102, which can be, for example, a display and touch screen for controlling the cryogenic grinding system 50. In one example, the display interface 102 can be, for example, a display and touch screen with a graphical user interface (GUI) that includes buttons or other GUI interface elements that allow the user to control the display of the cryogenic grinding system 50. The body 100 can also include a stop button 108 that immediately stops the cryogenic grinding system when pressed. In one example, the stop button 108 can be, for example, an emergency stop button that stops the system in the event of a malfunction or in the event that the user incorrectly operates the system. The body 100 also includes a series of legs 106a-106c. In one example, any one or more of the legs 106a-106c may be a mass-cell or any other type of mass sensor for determining the weight of the sample in the sample holding vessel 200 and / or the weight of the cryogen supplied to or contained in the sample holding vessel 200. Figure 1A In the example shown in , the front leg 106a is shown as a mass measurement unit. The mass measurement unit can provide an output or resistance indicating the weight or mass of any one or combination of samples in the sample holding vessel 200 and / or the weight of the cryogen supplied to or contained in the sample holding vessel 200.

[0041] As an alternative to the aforementioned display interface and / or the described automated and / or semi-automated control, the cryogenic grinding system 50 may instead be manually or analog controlled. For example, any one or combination of the amount of cryogen introduced into the container, the grinding duration of at least one blade, or the grinding speed of at least one blade may be controlled via any one or combination of a switch, a lever, or a dial. In addition, the system may provide feedback via any one or combination of an indicator light, an LCD screen(s), and / or an audible indicator.

[0042] Go to Figure 1A and Figure 1B The sample holding vessel 200 may, for example, include a handle 208 and may have an outer wall 202. The sample holding vessel 200 may also include an inner wall (e.g., Figure 4AThe sample holding vessel 200 may include an inner wall 252 therein and may, for example, have an insulating material, a gas, a fluid, or may be evacuated so that a vacuum exists between the outer wall 202 and the inner wall 252 to insulate the sample and / or cryogen provided to the sample holding vessel 200 from the surrounding environment.

[0043] like Figure 2 As shown in , the sample-holding vessel 200 may include a blade drive arrangement 216 that may be configured to be received by the blade drive opening 116 of the body 100 when the sample-holding vessel 200 is slid into the opening 101 by a user. Additional details of the blade drive arrangement 216 are described in more detail below.

[0044] The sample holding vessel 200 may also include a sample supply opening having a handle 214 . Figure 3A and Figure 3B A view of a sample holding vessel 200 is shown, which may be similar to that of FIGS. 1 to 21 . Figure 2 The handle 214 may be connected to a supply door 217 that is pivotally connected to a cover 240 of the sample holding vessel 200. As noted above, the supply door 217 may be pivotally connected to the supply door 217, allowing a user to move the sample holding vessel 200 generally in the direction R ( Figure 3B ) so that the sample can be provided to the sample holding vessel 200. Once the sample is provided to the sample holding vessel 200, the supply door 217 can be closed. The installation of the sample holding vessel 200 into the opening 101 of the body 100 and the rotation of the engagement rod 110 can cause a downward or sealing force to be applied to the supply door 217 and / or the handle 214. As mentioned above and described in further detail below, one or more clamping members can apply an upward force (e.g., Figure 1A 112a and 112b. The aforementioned upward force may cause the supply door 217 and / or the handle 214 to be pressed against the corresponding surface in the blade drive opening 116, thereby causing the supply door 217 to be pressed downward and seal, minimize and / or prevent the escape of gas, liquid or sample placed in the sample holding vessel 200 during processing. Either or both of the supply door 217 and the supply opening of the sample holding vessel 200 may have (one or more) gaskets or seals to further improve the sealing interface between the supply door 217 and the corresponding opening. (One or more) gaskets or seals may include any suitable sealing interface known in the art.

[0045] Figure 3A and Figure 3B An example of the sample holding vessel 200 removed from the body 1000 is shown. Figure 4A and Figure 4BAn example of a sample holding vessel 200 is shown having a top section 200a separated from a bottom section 200b. Figure 3A and Figure 3B As shown in , the sample holding vessel 200 may also include a blade drive support portion 222 and a blade drive coupler 220 as part of the blade drive arrangement 216. Figure 5A and Fig. 6A As best shown in the cross-sectional view of , the blade drive support portion 222 may, for example, include one or more bearings or bushings for rotatably supporting the blade shaft 206. The blade drive coupling 220 may, for example, be connected to the blade shaft 206 or otherwise configured to provide a rotational force to the blade shaft 206. The blade drive coupling 220 may, for example, include Figure 5B , which may be configured to engage with the drive coupling 120 of the body 100 and rotate simultaneously with the drive coupling 120. Figure 5B and Figure 6B As best shown in FIG. 1 , the blade drive coupling 220 and the drive coupling 120 may be configured to be engaged when engaged by a user in a direction F ( Figure 1A ) is engageably coupled when the engagement rod 110 is pulled, which causes the blade drive coupling 220 to move in the direction P ( Figure 5B )move. Figure 5B An example of the blade drive coupling 220 and the drive coupling 120 are shown in a disengaged position (eg, to allow the sample-holding vessel 200 to be installed into or removed from the body 100 ). Figure 6B An example of a blade drive coupling 220 and a drive coupling 120 are shown in an engaged position (eg, to transmit the rotational force provided by the motor to the blade drive coupling 220). An example of a motor is shown in FIG. Figure 8 Shown in the figure as reference numeral 172.

[0046] Figure 3A and Figure 3B An example of the exhaust port 234 and the refrigerant supply port 232 is shown. The refrigerant supply port 232 may be configured to be placed in contact with a refrigerant supply portion (eg, Figure 5A , Fig. 6A and Figure 7 The refrigerant supply section 132 in the embodiment is fluidly connected. Figure 3A and Figure 3B As shown in the example of , the cryogen supply port 232 may, for example, have a recess surrounding the opening. The recess may, for example, improve the sealing surface area between the cryogen supply port 232 and the cryogen supply portion of the body 100. Figure 5A , Fig. 6A and Figure 7In the cryogen supply port 232 and cryogen supply part 132 in the body 100, any one or both may have (one or more) gaskets or seals to further improve the sealing interface between cryogen supply port 232 and cryogen supply part 132. (One or more) gaskets or seals may include any suitable sealing interface known in the art. Cryogen supply port 232 and cryogen supply part 132 may be configured to be spaced apart from each other when sample holding vessel 200 first slides into body 100. Once sample holding vessel 200 slides completely into body 100, and engagement rod 110 is pulled in direction F, cryogen supply port 232 and cryogen supply part 132 may be moved to engage (e.g., in direction P), thereby causing sealing or partial sealing and allowing fluid communication between cryogen supply port 232 and cryogen supply part 132.

[0047] The exhaust port 234 of the sample holding vessel 200 may be configured to be placed in contact with an exhaust conduit (eg, Figure 8 The exhaust pipe 134 in the embodiment is fluidly connected. Figure 3A and Figure 3B As shown in the example of, the exhaust port 234 may, for example, have a recess surrounding the opening. The recess may, for example, improve the sealing surface area between the exhaust port 234 and the exhaust duct interface of the main body 100. Either or both of the exhaust port 234 and the exhaust duct interface may have (one or more) gaskets or seals to further improve the sealing interface between the exhaust port 234 and the exhaust duct 134. (One or more) gaskets or seals may include any suitable sealing interface known in the art. The exhaust port 234 and the exhaust duct 134 may be configured to be spaced apart from each other when the sample holding vessel 200 first slides into the main body 100. Once the sample holding vessel 200 is completely slid into the main body 100, and the engagement rod 110 is pulled in the direction F, the exhaust port 234 and the exhaust duct 134 may be moved to engage (e.g., in the direction P), thereby causing a seal or partial seal and allowing the fluid communication between the exhaust port 234 and the exhaust duct 134.

[0048] Figure 4A and Figure 4BAn example of a sample holding vessel 200 is shown having a top section 200a separated from a bottom section 200b. The top section 200a may, for example, include a supply door 217 and an optional handle 214 hingedly connected thereto via a hinge 219. The top section 200a may also include a blade drive support portion 222 and a blade drive connector 220 having a blade shaft 206 rotatably mounted to the top section 200a via one or more bearings and / or bushings. The blade drive support portion 222 may also include a seal, gasket, or O-ring configured to prevent fluid from escaping from the sample holding vessel 200 via an interface between the top section 200a and the rotatable blade shaft 206. In one example, the seal, gasket, or O-ring may include a Teflon TM (polytetrafluoroethylene). Figure 4B As shown in FIG. 1 , the blade shaft 206 may, for example, have one or more blades 204a connected thereto. Figure 4B Only a single blade is shown in FIG, but it is noted that there may be any number of blades as permitted by the space limitations of the sample holding vessel 200. For example, Figure 1B In one example, blade shaft 206 may be replaced with two blades mounted thereto. One or more blades may be formed by a rigid material such as steel or stainless steel, and may be hardened or otherwise processed to increase the strength or rigidity of blade, especially at the contact leading edge 204c of blade 204b. In one example, the leading edge 204c of (one or more) blades may be sharp and / or may include a series of ridges or other patterned or randomized surface irregularities that may further improve the efficiency of the blade in reducing the sample. In some examples, blade may be replaceably connected to blade shaft 206 to allow a user to replace or otherwise repair blade. In one example, blade 204b may be threadedly connected to shaft 206, or may be held to shaft via a bolt threadedly connected to the bottom of blade shaft 206.

[0049] The top section 200a is configured to be mounted to the bottom section 200b. The bottom section 200b may include an outer wall 202 and an inner wall 252, a handle 208, and a sealing channel or interface 233. In one aspect, the sealing channel or interface may be configured to receive a gasket or a seal such as an O-ring. In one example, the top section 200a and the bottom section 200b may be provided with a Teflon seal, for example, at either or both of the top section 200a and / or the bottom section 200b. TM (polytetrafluoroethylene) seals, gaskets or O-rings. For example, the top section 200a may have a top section seal 236. The top section seal 236 may include Teflon TM(polytetrafluoroethylene) seals, gaskets or O-rings. Although the described examples include one or more Teflon TM Gasket, but note that the gasket(s) or seal(s) may comprise any suitable sealing interface known in the art.

[0050] like Figure 4C As shown in FIG. 1 , the top section 200a may, for example, have a series of studs or protrusions 244 ( Figure 4C ), which is configured to be received by the corresponding receiving opening 235 of the bottom section 200b to align the top section 200a with the bottom section 200b. The installation of the sample holding vessel 200 into the opening 101 of the body 100 and the rotation of the engagement rod 110 can cause a downward or sealing force to be applied to the top section 200a and / or the bottom section 200b. As mentioned above and described in further detail below, one or more clamping members can apply an upward force (e.g., Figure 1A The aforementioned upward force may cause the top section 200a to be pressed against the bottom section 200b, thereby causing the top section 200a to be pressed downward and seal, minimize and / or prevent the escape of gas, liquid or sample placed in the sample holding vessel 200 during processing. Once the engagement rod 110 is rotated to the release position, the top section 200a can be separated from the bottom section 200b to, for example, remove the sample and / or clean or reprocess and / or refurbish the sample holding vessel 200.

[0051] Note also that, despite Figure 4C The middle stud or protrusion 244 is shown as being located on the top section 200a, but the stud or protrusion 244 may instead be at the bottom section 200b, and as an alternative, the receiving opening may be at the top section 200a. In addition, other methods of aligning the top section 200a with the bottom section 200b may be implemented. For example, the top section 200a may, for example, have a cylindrical protrusion that is configured to fit into an opening in the bottom section 200b.

[0052] In another example, the bottom section 200b may also include a series of threaded fastener receiving openings (eg, Figure 4A 234 in the figure). Note that although Figure 4AOnly three fastener receiving openings 235 are referenced and twelve are shown in total, but any number of threaded fastener receiving openings can be implemented.Threaded fastener receiving openings can be constructed and positioned on flange 242 to align with the corresponding through holes in top section 200a.For example, top section 200a may include a series of through holes, which are positioned to align with the threaded fastener receiving openings in bottom section 200b.In order to seal top section 200a and attach to bottom section 200b, a series of fasteners (such as bolts) can pass through this series of through holes of top section 200a and be threadedly connected to the fastener receiving opening in bottom section 200b and tighten appropriately.Top section 200a can be separated from bottom section 200b by reversing the aforementioned process.Top section 200a can be separated from bottom section 200b to, for example, add sample to sample holding vessel 200, remove sample, and / or clean or reprocess and / or renovate sample holding vessel 200.

[0053] Figures 7 to 9 Additional views of the body 100 of an example cryogenic grinding system 50 are shown. Figure 7 FIG. 2 shows a cross section of an example of a body 100 with the sample holding vessel 200 removed. Figure 1A Pull the engagement rod 110 in the direction F shown in FIG. Figure 1A and Figure 2 ) causes the container 200 to engage with the opening 101 of the body 100 or otherwise be retained in the opening 101 of the body 100. In one example, rotating the engagement rod may result in activation of the engagement system. For example, rotating the engagement rod 110 in direction F may cause one or more pressing members to press upward in direction P (see Figure 1A and Figure 7 ), the pressing member can press upward, thereby pressing the guide rails 210a and 210b against the top of each corresponding track 112a and 112b of the body 100 and applying a clamping force to the sample holding vessel 200. The pressing member can, for example, include one or more cams 152 rotatably mounted in the body 100. The one or more cams 152 can have a cam profile with an increasing radius. The cam profile can be slidably mounted with one or more force transition members (e.g., Figure 2 The force transition member 182 shown in FIG. is in contact. Note that although Figure 2 Only a single force transition member 182 is labeled in FIG. 1 , but similar or identical force transition members (hidden from view) may be present on the opposite side of the body 100, within the opening 101. The increase in the radius of the cam profile may cause one or more slidably mounted force transition members 182 to translate upward in the direction P, thereby causing the pressing member to press upward, moving the guide rails 210a and 210b ( Figure 2) is pressed against the top of each respective track 112a and 112b of the body 100 and applies a clamping force to the sample holding vessel 200, for example, to seal the top section 200a to the bottom section 200b and / or seal the supply door 217 with the flange 242. The foregoing steps may be reversed to release the sample holding vessel 200 from the body 100. For example, rotating the engagement rod 110 opposite the direction F causes the one or more cams 152 to rotate in the direction R such that the reduced radius section of the cam contacts the force transition member(s) 182, thereby causing the force transition member(s) 182 to retract in the direction D and reduce or remove the upward force applied to the rails 210a and 210b. Retraction may cause the sample-holding vessel 200 to move downwardly relative to the body 100 in direction D, which may cause the blade drive coupling 220 to disengage from the drive coupling 120, the exhaust port 234 to separate from the exhaust conduit 134, and / or the cryogen supply port 232 to separate from the cryogen supply 132. Once the blade drive coupling 120 is disengaged from the drive coupling 220, the exhaust port 234 to separate from the exhaust conduit 134, and the cryogen supply port 232 to separate from the cryogen supply 132, the sample-holding vessel 200 may be slid out of the body 100, as shown in FIG. Figure 2 As shown in .

[0054] In addition to the foregoing features, the sample holding vessel 200 may include one or more thermistor or temperature sensor ports 299a ( Figure 5A ) or 299b( Fig. 6A ). In one example, one or more thermistor or temperature sensor ports 299a and / or 299b may be configured to slidably receive one or more temperature sensors or thermistors. Fig. 6A In the example shown in FIG. 1 , two or more ports may be formed in the side of the sample holding vessel 200 so that when the guide rails 210a and 210b of the sample holding vessel 200 slide into the body 100 via the tracks 112a and 112b and the engagement rod 110 is rotated as mentioned above, one or more thermistors (e.g., thermistor 199) of the body 100 contact the surface of the inner wall (e.g., inner wall 252) of the sample holding vessel 200 so as to form a thermal path between the inner wall 252 and the thermistor 199, thereby allowing a control system (described in further detail below) to determine the temperature within the sample holding vessel 200. In one aspect that can be used for or in lieu of the aforementioned configuration, the sample holding vessel 200 may have a thermistor opening 299b. The thermistor opening may operate similarly to the aforementioned configuration, but the thermal contact between the thermistor and the inner wall of the sample holding vessel 200 may instead occur at the bottom of the sample holding vessel 200.

[0055] In yet another aspect that may be used in place of or in combination with any or both of the foregoing configurations, a thermistor or other temperature sensor or multiple thermistors or temperature sensors may be part of the sample holding vessel 200 (e.g., mounted to any interior wall of the sample holding vessel 200). Fig. 6A The thermistor 199 shown in FIG. 1 may instead be an electrical contact portion that provides electrical contact between the thermistor(s) or temperature sensor(s) of the body 100 and the sample holding vessel 200 .

[0056] As mentioned above, the drive coupling 120 can be configured to rotate in at least one of two directions, and can be configured to provide a rotational force to the (one or more) blades within the sample holding vessel 200 after being coupled to the blade drive coupling 220. The drive coupling 120 can be rotatably supported within the body 100 via the blade drive shaft 121. The blade drive shaft 121 can be rotatably supported via a bushing, a bearing, or a combination thereof. Figure 8 As best shown in FIG. 1 , the drive shaft 121 may be mechanically or otherwise operably connected to a motor 172 of the body 100. Some examples of a mechanical or operative connection between the motor 172 and the blade drive shaft 121 may include a belt or chain drive, a gear train, or in an alternative construction, the motor may be directly coupled to the blade drive shaft 121.

[0057] like Figure 8 , the exhaust duct 134 may be in fluid communication with a blower or ventilation device 150. The ventilation device 150 may be configured to draw gas from the exhaust duct 134 and lead to an outlet opening 189. The outlet opening 189 may be configured to remain open to the surrounding atmosphere, or may be configured to have an additional pipeline or pipe connected thereto for discharging the fluid (e.g., gas) generated during the processing of the sample contained in the sample holding vessel 200. The blower or ventilation device 150 may be any suitable electric blower or fan known in the art. As described in further detail below, the blower or vent may be powered by a controller or otherwise operated by a controller.

[0058] like Fig. 9As best shown in , the cryogen supply 132 of the body 100 can be fluidly connected to the cryogen input end 133. The cryogen input end 133 may include an electronically or hydraulically controlled valve 135 for controlling the supply of cryogen via the cryogen supply 132 to the cryogen supply port 232 of the sample holding vessel 200. As discussed in further detail below, the electronically or hydraulically controlled valve 135 can be controlled by a controller or otherwise powered by the controller. The cryogen supply can, for example, be insulated (e.g., via insulation 136). Insulation 136 can prevent condensation accumulation due to the cryogen supply having a temperature below the dew point of the surrounding environment. Note that although Fig. 9 Only partial insulation is shown in the figure to prevent obstruction of vision, but the entire cryogen conduit / tube can be insulated. The cryogen input end 133 can be configured to connect to a cryogen source, such as a liquid nitrogen source, for example. The cryogen input end 133 can be, for example, a standard connector (e.g., a National Pipe Thread "NPT" 3 / 8 type connector).

[0059] Fig.10 910, motor 914, and / or valve 916. Figure 1A , Figure 2 , Figure 5A , Fig. 6A , Figure 7 , Figure 8 and Fig. 9 ), the temperature sensor(s) 912 may be similar to the thermistor 199 ( Fig. 6A ), the blower 950 may be similar to the blower or ventilation device 150 ( Figure 5A , Fig. 6A , Figure 7 , Figure 8 and Fig. 9 ), motor 914 may be similar to motor 172 ( Figure 8 ), and valve 916 may be similar to valve 135 ( Fig. 9 ).

[0060] In an example operation of the controller, once it is determined that the sample is placed in the sample holding vessel 200 and the sample holding vessel 200 is placed in the main body 100. The user can indicate via the display interface 102 that the sample is to be processed. For example, the display interface 102 may, for example, have a graphical user interface (GUI) with an icon or other visual indicator, and the controller can determine that the user has touched or pressed an icon or other visual indicator indicating that the user wishes to process the sample. It is noted that although GUI is referenced throughout the disclosure as providing two indicators to the user and for allowing the user to control or type input into the device, in another aspect, the user can provide instructions via a switch knob. In addition, instead of a screen, a light or other indicator can be used to indicate the status of the device to the user.

[0061] Once a determination is made that the container is placed in the body 100 and the engagement rod 110 is rotated to the locked position, the controller may provide an electric current or signal to the valve 916 to provide the cryogen to the sample holding vessel 200. In one example, the user may input any one or combination of the weight, volume or type of the sample in the sample holding vessel 200, and the controller determines the volume of cryogen to be supplied to the sample holding vessel 200 based on any one or combination of the weight, volume or type of the sample input by the user. In another example, the controller may determine the weight of the sample placed in the sample holding vessel 200 based on the output from (one or more) mass sensors 910, and may automatically supply an appropriate volume of cryogen and / or may suggest an appropriate volume of cryogen to the container via the display interface 102. The GUI may then be controlled to request confirmation from the user and / or may provide an override option to allow the user to add or subtract the volume of cryogen from the suggested amount. In yet another example, once the user indicates that the sample is to be processed, the system may automatically supply a set volume of cryogen. In any one or combination of the foregoing examples, the initial volume of cryogen can be between 70-300 milliliters (mL). In yet another example, the initial volume of cryogen can be between 100-150mL. In a preferred aspect, the initial volume of cryogen can be between 140-150mL. In yet another preferred aspect, the initial volume of cryogen can be between 185-210mL. In one example, the controller can set the initial volume of the cryogen provided to the sample holding vessel 200 via valve 916 to approximately 200mL. In one example, the controller can use the output from (one or more) mass sensors to determine when to open / close valve 916 when the appropriate volume of cryogen has been added to the sample holding vessel 200.

[0062] In one example operation of a controller that may be used with the foregoing aspects, once an appropriate amount of cryogen, or more preferably when cryogen, is added to the sample holding vessel 200, the controller may operate the motor 914 to cause the blade(s) (e.g., Figure 4B The blade 204(b) and / or Figure 1B The blade 204a in the sample container 200 is rotated. In a preferred example, when cryogen is added to the sample container 200, the blade can be controlled to rotate in a first direction and then in a second reverse direction in a "pulse" motion. By alternating the direction of the blade as described above, a more uniform treatment of the sample with cryogen can occur, and the adhesion of the sample to the blade can be reduced. Once the cryogen of the desired volume is added, the controller can pause the rotation of the blade to allow the cryogen to remove heat from the sample and reduce the temperature of the sample to the desired temperature. The controller can determine whether the temperature of the sample has been reduced to the desired temperature by monitoring the output of (one or more) temperature sensors 912. Once the controller determines that the temperature of the sample has been reduced to the desired temperature, the motor can be powered again to grind or otherwise reduce the particle size of the sample in the sample container 200. In one example, the GUI displayed on the display interface 102 can indicate the temperature of the sample in the sample container 200. In one aspect, the GUI may include an indicator or part that allows the user to override the desired temperature of the sample and / or set the desired temperature before the motor is controlled again to rotate the blade, so that additional grinding of the sample or reduction of the particle size occurs.

[0063] In one example, the temperature of the sample in the sample holding vessel 200 can be continuously monitored. In the aforementioned example, an upper temperature limit and a lower temperature limit can be set, and if the temperature of the sample in the sample holding vessel 200 increases to above the threshold temperature or fails to be reduced to below the threshold temperature, the controller can supply additional cryogen. In one example, the cryogen can be liquid nitrogen with a boiling point of about -198 degrees Celsius, and the threshold temperature can be any value between -50 to -198 degrees Celsius. In another example, the threshold temperature can be any value between -100 to -170 degrees Celsius. In a preferred example, the threshold temperature can be -140 degrees Celsius. Therefore, in the aforementioned example, if the controller determines that the temperature of the sample in the sample holding vessel 200 is higher than -140 degrees Celsius, the valve 916 is controlled to provide additional liquid nitrogen to the sample holding vessel 200 until the temperature is determined to be reduced to at least 140 degrees Celsius. Although the aforementioned example provides advantages, it is noted that any temperature or temperature range (especially in the aforementioned range) can be used as the threshold temperature.

[0064] In any of the foregoing examples, the controller may also control (one or more) blowers 950. The blower may, for example, be controlled to remove gas that accumulates within the sample holding vessel 200 when the cryogen boils. In some examples, the controller may turn on the blower at any time when cryogen is present in the sample holding vessel 200. In another example, the controller may turn on the blower when it is determined that the temperature within the sample holding vessel 200 has dropped below a certain temperature. For example, if a desired or optimal temperature range for the sample is set or provided, the blower may be turned on when the temperature of the sample in the sample holding vessel 200 approaches or drops below the desired temperature range.

[0065] In another example, the motor speed and thus the blade speed may be controlled based on any one or combination of the aforementioned determinations. For example, the blade speed may be controlled to be slower when the detected temperature is above a threshold temperature, and then may be controlled to increase when the temperature drops below the threshold temperature. In another example, after the user indicates that the sample in the sample holding vessel 200 is to be processed, the blade speed may be controlled to be lower in a first period of time, and then may be controlled to increase to a higher speed in a second period of time after the first period of time.
