Description

Technical Field

[0001] This utility model relates to the field of cooling and preservation equipment, and in particular to an ice box used in experimental operations. Background Technology

[0002] During experimental procedures, it is necessary to maintain reagents and samples at low temperatures, hence the development of experimental ice boxes. An experimental ice box is a container that maintains reagents and samples at a low temperature during experimental operations, ensuring their safety during storage, handling, and experimental procedures. Before use, the experimenter can pre-cool the ice box in a refrigerator or a -20°C freezer according to the required temperature range for the experiment. Once the ice box reaches the required experimental temperature, it can be removed and maintained within the required temperature range for tens of minutes or several hours during the experiment.

[0003] Because ice boxes need to maintain the required temperature range for experiments, they must have a temperature display function. However, the temperature display functions of various ice boxes currently vary greatly. Most existing ice boxes lack temperature indication or cannot accurately indicate the specific temperature. For example, some use a solvent with temperature indication function, where the temperature is indicated by the change in the solvent's color. However, the color change may be difficult to detect, and the solvent may become unstable after one use, leading to inaccurate temperature indication. Alternatively, a few existing ice boxes have precise temperature indication functions, such as by adding a temperature probe inside the ice box. The probe detects the temperature and displays it on an LCD screen on the surface of the ice box, which can accurately detect the ice box temperature. However, the combination of sensor and display increases the production cost of the ice box, which is not conducive to its commercial promotion. Moreover, the ice box needs to be pre-cooled in a -20°C freezer, and the low temperature environment will also affect the lifespan of the sensor and display. Therefore, there is a need in this field for an ice box that can accurately display temperature, is inexpensive, and is reusable. Utility Model Content

[0019] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0020] In the following detailed description, reference can be made to the accompanying drawings, which form part of this application and illustrate specific embodiments of the present application. In the drawings, similar reference numerals describe substantially similar components in different figures. Specific embodiments of the present application are described in sufficient detail below to enable those skilled in the art to implement the technical solutions of the present application. It should be understood that other embodiments may also be utilized, or structural, logical, or electrical changes may be made to the embodiments of the present application.

[0021] Laboratory experiments typically require specific temperatures for samples, reagents, or reaction systems. For example, most commonly used biological enzymes need to be kept within a temperature range of 0-4℃. Therefore, the ice pack only needs to maintain the enzyme temperature within this range during the experiment. Consequently, the temperature indication function of the ice pack is not critical; only relatively accurate temperature indication (within ±1℃) is required.

[0022] Therefore, this application proposes an ice box that can continuously maintain the required temperature range during experimental operations and accurately display the temperature of the ice box. It can meet the low-temperature experimental environment prompting needs of general laboratory scenarios, facilitate timely information on the temperature status of reagents, samples, or reaction systems during experiments, and take timely countermeasures. It can avoid events that affect experimental results, such as reagent failure, sample degradation, and incomplete experimental reactions caused by prolonged exposure to unsuitable temperatures, thereby reducing economic losses in the laboratory. Moreover, for consumables used frequently in laboratories, the ice box of this application has a low manufacturing cost and can be reused, which can effectively save experimental costs.

[0023] The technical solution of this application will be further illustrated below through specific embodiments. Those skilled in the art should understand that the following description is merely for the convenience of understanding the technical solution of the application and should not be used to limit the scope of protection of this application.

[0024] Figure 1 This is a perspective view of an ice box according to an embodiment of the present application. Figure 2This is a front view of an ice pack according to an embodiment of this application. As shown, the ice pack 100 can be used during experimental operations to continuously maintain the required temperature range for reagents, samples, or reaction systems.

[0025] refer to Figure 1 The ice box 100 includes an ice box body 110 and a temperature indicator 120. The temperature indicator 120 is located on the side of the ice box body 110 and can be used to indicate the temperature of the ice box body 110, so as to facilitate timely information on the temperature status of reagents, samples or reaction systems during experiments.

[0026] refer to Figure 2 In some embodiments, the ice box body 110 is a cuboid, and its upper surface includes a receiving area 111 with one or more holes 1111. Test tubes (such as PCR tubes) can be placed through the holes 1111, thereby allowing the ice box to maintain the temperature of the reagents or samples inside the test tubes. In some embodiments, the receiving area may include 8×12 holes to accommodate a single PCR tube, or an 8-well PCR tube array, or an 8×12-well PCR plate. In some embodiments, the pore diameter may be 6.2 mm to accommodate 0.2 ml PCR tubes.

[0027] In some embodiments, the upper surface of the ice box body further includes a marking area 112, configured to mark the location of the holes, facilitating the marking of reagent or sample numbers in test tubes during experimental operations and avoiding sample addition errors. In some embodiments, the marking area 112 includes a first marking area 1121 and a second marking area 1122, respectively disposed on the edges of two adjacent sides of the ice box body, and the specific location of the holes can be marked by the cooperation of the first marking area and the second marking area. In some embodiments, the first marking area can be a numerical marking (e.g., 1-12), and the second marking area can be a letter marking (e.g., AH). As those skilled in the art will understand, the first marking area and the second marking area can also be type markings. In some embodiments, the first marking area 1121 can be located on the long side of the rectangular upper surface, and the second marking area 1122 can be located on the short side of the rectangular upper surface.

[0028] In some embodiments, the main body of the ice box can be made of solid aluminum, which has good thermal conductivity and can effectively shorten the time for the ice box to be placed in a refrigerator or a -20°C freezer for pre-cooling. It can continuously maintain the temperature of the reagents or samples in the test tubes. In addition, the material has a high density and heavy weight, which can ensure stability on the laboratory table and prevent the test tubes on the ice box from being knocked over during the experimental operation, thus avoiding contamination of the experiment. It will not affect the reagents or samples placed in the test tubes and will not affect the test results.

[0029] In some embodiments, the temperature indicator 120 includes multiple indicator areas 121, which can indicate temperature changes in the ice box body through color changes of different indicator areas. For example, when the temperature rises, the indicator area will change from black to red, and when the temperature drops, the indicator area will change from red to black. The temperature change of the ice box body can be determined by the difference in color between adjacent indicator areas. In some embodiments, the temperature indicator 120 can be affixed to the side of the ice box body opposite to the first marking area, so that the temperature indicator is located in the optimal field of vision area for the experimenter, facilitating the observation of temperature changes. In some embodiments, the temperature indicator 120 may also include multiple digital areas 122, which can be located inside or outside the indicator areas 121, and can be used to identify the temperature values ​​of the corresponding indicator areas for easy observation by the experimenter.

[0030] In some embodiments, the temperature indicator 120 may be a thermal indicator paper, which can be repeatedly reused, thus reducing waste and lowering experimental costs in the laboratory. According to one embodiment of this application, the thermal indicator paper may include 11 indicator areas, with corresponding numerical areas ranging from 1°C to 12°C. For example, if the first three indicator areas are red, it indicates that the temperature of the ice box body is 3°C; when the fourth indicator area turns red, it indicates that the temperature of the ice box body is 4°C. In some embodiments, the temperature indicator 120 may also be other indicator devices, such as color-changing temperature sensors.

[0031] In some embodiments, the ice box 100 may further include a waterproof sealing layer 130, which may be disposed on the outside of the temperature indicator 120 and may seal the temperature indicator to protect it from condensation during the freeze-thaw process, preventing the heat-sensitive material from becoming wetted and deteriorating or dissolving. In some embodiments, the waterproof sealing layer is made of a transparent material to facilitate observation of the temperature indicator's display results by the laboratory operator. In some embodiments, the waterproof sealing layer may be a plastic film.

[0032] The ice box of this application can accurately indicate the temperature of the ice box through the changes of multiple indicator zones of the temperature indicator device. It can meet the low-temperature experimental environment indication requirements in general experimental scenarios, making it convenient to know the temperature status of reagents, samples and reaction systems in a timely manner during the experiment, and take timely countermeasures to avoid events that affect experimental results, such as reagent failure, sample degradation and incomplete experimental reaction caused by prolonged exposure to unsuitable temperatures. This can reduce economic losses in the laboratory. Moreover, the ice box of this application has a low manufacturing cost, which is conducive to the commercial promotion of the ice box. It can also be recycled and reused, saving experimental costs.

[0033] The above embodiments are for illustrative purposes only and are not intended to limit the present invention. Those skilled in the art can make various changes and modifications without departing from the scope of the present invention. Therefore, all equivalent technical solutions should also fall within the scope of the present invention.
