Abstract
Description
Technical Field
[0001] This utility model relates to the field of pipette container technology, and in particular to a pipette container that prevents contamination during handling. Background Technology
[0002] A pipette is a commonly used volumetric instrument in the laboratory, used to accurately transfer and dispense a certain volume of liquid. It is widely used in scientific research, clinical practice, pharmaceuticals and other fields that require precise liquid handling. Multiple pipettes are often stored in stainless steel cylinders so that they can be centrally sterilized by dry heat after use.
[0003] Existing pipette containers mainly consist of stainless steel cylinders with a placement slot at the top. The pipette is stored by placing it into the placement slot, and can be used after being removed from the placement slot.
[0004] When using existing pipette containers, because multiple pipettes are stored in the same stainless steel container, unused pipettes are easily contaminated when they are taken out. This can lead to different experimental samples or reagents being mixed, resulting in unreliable experimental data and reducing the accuracy of experimental results.
[0005] To address the aforementioned problems, this application proposes a pipette container that prevents contamination during handling. Utility Model Content
[0006] To address the problems mentioned in the background section, this invention provides a pipette container designed to prevent contamination during handling. This container reduces the probability of contaminating unused pipettes during handling without affecting the dry heat sterilization efficiency. It also prevents mixing of different experimental samples or reagents, thereby improving the accuracy of experimental results. Furthermore, it facilitates sealing the stainless steel container when storing the pipette, reducing the probability of contamination during storage. During dry heat sterilization, the vent can be left open to promote air circulation inside and outside the stainless steel container, accelerating the dry heat sterilization process.
[0007] To achieve the above objectives, this utility model provides the following technical solution: a pipette container for preventing contamination during handling, comprising a stainless steel cylinder, an inner placement groove, a fixed tube fixedly disposed at the bottom of the placement groove, a placement plate fixedly disposed on the side of the fixed tube, the side of the placement plate being fixedly connected to the interior of the stainless steel cylinder, a plurality of placement holes being formed inside the placement plate, a plurality of first partitions being fixedly disposed at the top of the placement plate, a plurality of baffles being disposed between the plurality of first partitions, a limiting block being fixedly disposed on one side of each of the baffles, a handle being fixedly disposed at the top of each of the limiting blocks, and the other side of each of the baffles being rotatably connected to the side of the fixed tube, a plurality of second partitions being fixedly disposed at the bottom of the placement plate, a plurality of limiting grooves being formed at the top of the stainless steel cylinder, the interiors of the plurality of limiting grooves respectively fitting against the sides of the plurality of limiting blocks, and a plurality of vent holes being formed on the side of the stainless steel cylinder.
[0008] As a preferred embodiment of the present invention for preventing contamination during pipetting, one side of each of the first partitions is fixedly connected to the side of a fixed tube, and the other side of each of the first partitions is fixedly connected to the interior of a stainless steel cylinder. The first partitions facilitate the separation of the pipettes.
[0009] As a preferred embodiment of the present invention for preventing contamination during pipetting, one side of each of the second partitions is fixedly connected to the side of the fixed tube, and the other side of each of the second partitions is fixedly connected to the interior of the stainless steel cylinder. The second partitions facilitate the separation of the pipettes.
[0010] As a preferred embodiment of the present invention for preventing contamination during pipetting, the stainless steel cylinder is provided with a first limiting ring fixedly on its side, and the bottom end of the first limiting ring is provided with a first sliding groove. The first limiting ring facilitates the improvement of the stability of the first rotating ring during rotation.
[0011] As a preferred embodiment of the present invention for preventing contamination during pipetting, the stainless steel cylinder is provided with a second limiting ring fixedly on its side, and a second sliding groove is provided at the bottom end of the second limiting ring. The second limiting ring facilitates the improvement of the stability of the second rotating ring during rotation.
[0012] As a preferred embodiment of the present invention for preventing contamination during pipetting, the first groove is provided with a first rotating ring inside, and the side of the first rotating ring is rotatably connected to the inside of the first groove. The first rotating ring facilitates the improvement of the stability of the sealing ring during rotation.
[0013] As a preferred embodiment of the present invention for preventing contamination during pipetting, the second groove is provided with a second rotating ring inside, and the side of the second rotating ring is rotatably connected to the inside of the second groove. The second rotating ring facilitates the improvement of the stability of the sealing ring during rotation.
[0014] As a preferred embodiment of the present invention for preventing contamination during pipetting, a sealing ring is fixedly provided between the first rotating ring and the second rotating ring. The inner side of the sealing ring is in contact with the side of the stainless steel cylinder, and several venting grooves are provided inside the sealing ring to facilitate the control of the opening and closing of the venting holes.
[0015] Compared with the prior art, the beneficial effects of this utility model are:
[0016] 1. Several first slots are formed between several first partitions, and several second slots are formed between several second partitions. When a pipette needs to be stored, the handle is moved upward, causing the limiting block and baffle to rotate upward, opening the corresponding first slot. The pipette is then passed through the first slot and the placement hole, allowing it to be placed into the second slot. When the pipette needs to be removed, it is moved upward, disengaging it from the first and second slots, thus allowing it to be removed. Moving the handle downward causes the limiting block and baffle to rotate downward, sealing the corresponding first slot. During this process, other first and second slots are blocked by the baffle, the first partition, and the second partition, preventing different first slots from being stored. The first and second empty slots are not interconnected, preventing pipettes in different slots from coming into contact with each other. This reduces the probability of unused pipettes being contaminated. When dry heat sterilization is required, the stainless steel cylinder, first partition, second partition, baffle, and fixing tube are all made of stainless steel, which has high thermal conductivity. The vent holes facilitate the flow of hot air inside and outside the stainless steel cylinder, resulting in high dry heat sterilization efficiency for the pipettes. Thus, without affecting the dry heat sterilization efficiency of the pipettes, this device can reduce the probability of contaminating unused pipettes when they are used, making it less likely for different experimental samples or reagents to be mixed, thereby improving the accuracy of experimental results.
[0017] 2. The vent allows for the circulation of hot air inside and outside the stainless steel cylinder, thus accelerating the dry heat sterilization efficiency of the pipette. After the pipette has undergone dry heat sterilization, rotating the sealing ring seals the vent, preventing external dust from entering the stainless steel cylinder and contaminating the pipette. A baffle seals the top of the stainless steel cylinder to prevent external dust from entering and contaminating the pipette. When dry heat sterilization is required again, the sealing ring is reversed, connecting the vent groove to the vent. This opens the vent, facilitating the circulation of hot air inside and outside the stainless steel cylinder. This device allows for easy sealing of the stainless steel cylinder when the pipette is placed, reducing the probability of contamination, and allows the vent to be opened during dry heat sterilization, promoting air circulation and accelerating the dry heat sterilization process.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0026] Example 1
[0027] like Figures 1-4 As shown;
[0028] A pipette container designed to prevent contamination during handling includes a stainless steel cylinder 1.
[0029] To address the existing problems in the prior art, as disclosed in the background section above, "when using existing pipette containers, because multiple pipettes are stored in the same stainless steel container, unused pipettes are easily contaminated when they are taken out, which may cause different experimental samples or reagents to mix with each other, resulting in unreliable experimental data and reducing the accuracy of experimental results." In combination, this problem is obviously a real and difficult problem to solve. Therefore, in order to solve this technical problem, a first partition and a second partition are added to this application.
[0030] Furthermore:
[0031] like Figures 1 to 4 As shown:
[0032] Based on the above: the stainless steel cylinder 1 has a placement groove inside, a fixing tube 2 is fixedly installed at the bottom of the placement groove, a placement plate 3 is fixedly installed on the side of the fixing tube 2, the side of the placement plate 3 is fixedly connected to the inside of the stainless steel cylinder 1, a number of placement holes 4 are opened inside the placement plate 3, a number of first partitions 5 are fixedly installed at the top of the placement plate 3, a number of baffles 6 are provided between the number of first partitions 5, a limiting block 7 is fixedly installed on one side of each of the baffles 6, a handle 8 is fixedly installed at the top of each of the limiting blocks 7, the other side of each of the baffles 6 is rotatably connected to the side of the fixing tube 2, a number of second partitions 9 are fixedly installed at the bottom of the placement plate 3, a number of limiting grooves 10 are opened at the top of the stainless steel cylinder 1, the inside of each of the limiting grooves 10 is respectively attached to the side of each of the limiting blocks 7, and a number of vent holes 11 are opened on the side of the stainless steel cylinder 1.
[0033] In this implementation scheme: several first slots are formed between several first partitions 5, and several second slots are formed between several second partitions 9. Both the first and second slots are used to store pipettes. When a pipette needs to be stored, the handle 8 is moved upward, thereby causing the limiting block 7 and the baffle 6 to rotate upward, opening the corresponding first slot. The pipette is then inserted through the first slot into the placement hole 4, placing the pipette into the second slot inside the stainless steel cylinder 1. When the pipette needs to be removed, it is moved upward, disengaging it from the first and second slots, allowing it to be removed. After the pipette is removed, the handle 8 is moved downward, causing the limiting block 7 and the baffle 6 to rotate downward, sealing the corresponding first slot with the baffle 6. During this process, the other first and second slots are sealed by the baffle 6, the first partitions 5, and the second partitions 9. The partition 9 blocks the flow between the different first and second empty slots, preventing the pipettes in the different first and second empty slots from coming into contact with each other. This reduces the probability of unused pipettes being contaminated. When the pipettes need to be dry-heat sterilized, the stainless steel cylinder 1, the first partition 5, the second partition 9, the baffle 6, and the fixing tube 2 are all made of stainless steel, which has high thermal conductivity, facilitating heat transfer into the stainless steel cylinder 1. The vent 11 on the side of the stainless steel cylinder 1 allows for the circulation of hot air inside and outside the cylinder, resulting in high dry-heat sterilization efficiency for the pipettes. Thus, without affecting the dry-heat sterilization efficiency of the pipettes, this device reduces the probability of contaminating unused pipettes when they are used, making it less likely for different experimental samples or reagents to mix, thereby improving the accuracy of experimental results.
[0034] In an optional embodiment: one side of each of the first partitions 5 is fixedly connected to the side of the fixed tube 2, and the other side of each of the first partitions 5 is fixedly connected to the interior of the stainless steel cylinder 1.
[0035] In this embodiment, the first partition 5 facilitates the separation of several pipettes.
[0036] In an optional embodiment: one side of each of the second partitions 9 is fixedly connected to the side of the fixed tube 2, and the other side of each of the second partitions 9 is fixedly connected to the interior of the stainless steel cylinder 1.
[0037] In this embodiment, the second partition 9 facilitates the separation of several pipettes.
[0038] In an optional embodiment: a first limiting ring 12 is fixedly provided on the side of the stainless steel cylinder 1, and a first sliding groove is provided at the bottom end of the first limiting ring 12.
[0039] In this embodiment, the first limiting ring 12 helps to improve the stability of the first rotating ring 14 when it rotates.
[0040] In an optional embodiment: a second limiting ring 13 is fixedly provided on the side of the stainless steel cylinder 1, and a second sliding groove is provided at the bottom end of the second limiting ring 13.
[0041] In this embodiment, the second limiting ring 13 helps to improve the stability of the second rotating ring 15 when it rotates.
[0042] In an optional embodiment: a first rotating ring 14 is provided inside the first slide groove, and the side of the first rotating ring 14 is rotatably connected to the inside of the first slide groove.
[0043] In this embodiment, the first rotating ring 14 helps to improve the stability of the sealing ring 16 when it rotates.
[0044] In an optional embodiment: a second rotating ring 15 is provided inside the second slide groove, and the side of the second rotating ring 15 is rotatably connected to the inside of the second slide groove.
[0045] In this embodiment, the second rotating ring 15 helps to improve the stability of the sealing ring 16 when it rotates.
[0046] In an optional embodiment: a sealing ring 16 is fixedly provided between the first rotating ring 14 and the second rotating ring 15, the inner side of the sealing ring 16 is in contact with the side of the stainless steel cylinder 1, and a plurality of ventilation grooves 17 are provided inside the sealing ring 16.
[0047] In this embodiment, the sealing ring 16 facilitates the control of the opening and closing of the vent 11.
[0048] The working principle and usage process of this utility model are as follows: Several first slots are formed between several first partitions 5, and several second slots are formed between several second partitions 9. Both the first and second slots are used to store pipettes. When a pipette needs to be stored, the handle 8 is moved upward, thereby causing the limiting block 7 and the baffle 6 to rotate upward, opening the corresponding first slot. The pipette is then inserted through the first slot into the placement hole 4, placing the pipette into the second slot inside the stainless steel cylinder 1. When the pipette needs to be removed, it is moved upward, disengaging it from the first and second slots, allowing it to be removed. After the pipette is removed, the handle 8 is moved downward, causing the limiting block 7 and the baffle 6 to rotate downward, sealing the corresponding first slot with the baffle 6. During this process, the other first and second empty slots are blocked by baffle 6, first partition 5, and second partition 9, preventing flow between different first and second empty slots. This prevents the pipettes in different first and second empty slots from contacting each other, thus reducing the probability of unused pipettes becoming contaminated. When the pipettes need dry heat sterilization, the stainless steel cylinder 1, first partition 5, second partition 9, baffle 6, and fixing tube 2 are all made of stainless steel, which has high thermal conductivity, facilitating heat transfer into the stainless steel cylinder 1. The vent 11 on the side of the stainless steel cylinder 1 facilitates the flow of hot air inside and outside the cylinder, resulting in high dry heat sterilization efficiency for the pipettes. Therefore, this device can reduce the risk of contamination without affecting the dry heat sterilization efficiency of the pipettes. The probability of contaminating unused pipettes during use is reduced, making it less likely for different experimental samples or reagents to mix, thus improving the accuracy of experimental results. When dry heat sterilization of the pipettes is required, the vent 11 facilitates the flow of hot air inside and outside the stainless steel cylinder 1, accelerating the dry heat sterilization efficiency. After dry heat sterilization is completed, rotating the sealing ring 16 seals the vent 11, preventing external dust from entering the stainless steel cylinder 1 through the vent 11 and contaminating the pipette. The baffle 6 seals the top of the stainless steel cylinder 1, preventing external dust from entering the stainless steel cylinder 1 through the top and contaminating the pipette, thereby reducing the probability of pipette contamination. The first limiting ring 12 and the second limiting ring... Ring 13 facilitates the improvement of the stability of the first rotating ring 14 and the second rotating ring 15 during rotation, thereby facilitating the improvement of the stability of the sealing ring 16 during rotation. The connection between the sealing ring 16 and the stainless steel cylinder 1 has a certain frictional force, making it less likely to shake when the sealing ring 16 is placed. When the pipette needs to be dry-heat sterilized again, the sealing ring 16 is reversed, so that the vent groove 17 is connected to the vent hole 11. At this time, the vent hole 11 is open, which facilitates the circulation of hot air inside and outside the stainless steel cylinder 1. This makes it easier to seal the stainless steel cylinder 1 when the pipette is placed, so as to reduce the probability of contamination when the pipette is placed. When the pipette is dry-heat sterilized, the vent hole 11 can be opened to promote the circulation of air inside and outside the stainless steel cylinder 1 and accelerate the dry-heat sterilization speed of the pipette.
[0049] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
