Abstract
Description
Technical Field
[0001] This utility model relates to the field of microbial experimental technology, and specifically provides a storage box for microbial laboratories that facilitates the management and low-temperature preservation of pathogenic strains, for the long-term low-temperature preservation and management of quality control strains and pathogenic strains in microbial laboratories. Background Technology
[0002] Commonly used laboratory strain storage tools include: temporary sample bags, open-top small sample racks, and split-top storage boxes. These sample bags, racks, or boxes currently have the following problems: 1. Easy to spill: Currently, most laboratory strains are temporarily stored in small specimen racks before preservation. When taken out of the refrigerator, they are easy to spill and need to be rearranged according to their numbers. It is very time-consuming to reorganize them one by one according to their strain numbers and names. When the quantity is large, it can lead to repeated freeze-thaw cycles of the strains. 2. Difficulty in opening and closing the lid: After opening the lid and placing the strains, it is difficult to close the lid. Sometimes the whole box will escape. It is very time-consuming to reorganize the strains according to their numbers and names. When the quantity is large, it may cause the strains to freeze and thaw repeatedly. 3. Repeated freeze-thaw cycles: When taking strains from a low-temperature freezer, they should not be left outside for a long time. When quality control strains are needed, multiple strains need to be taken out every week. Taking them out takes time, and repeated freeze-thaw cycles will greatly shorten the lifespan of the strains and affect their biological characteristics. 4. Difficult to manage: The number of strains in the laboratory is very large, generally requiring at least 5 years of preservation, reaching tens of thousands of strains. Over time, single-box storage can easily lead to mixing, making it difficult to locate and search by section, which increases the difficulty of management. 5. Biosafety: The requirement for dual-person, dual-lock systems for strains in microbiology laboratories is difficult to achieve. Normally, this is addressed by setting up a separate laboratory room and locking the cryogenic freezer. However, this is difficult for most small laboratories to implement in a separate room for storing cryogenic freezers. Utility Model Content
[0003] The purpose of this invention is to provide a storage box for microbial laboratories that facilitates the management and low-temperature preservation of pathogenic strains, effectively solving the aforementioned problems.
[0004] The technical solution of this utility model is: a storage box for easy management and low-temperature preservation of pathogenic strains in a microbiology laboratory, comprising: an outer box 100, a sample box 200, and a sample rack 300. The outer box 100 includes a box body 101 and a front-opening box door 102. The box body 101 and the box door 102 are connected by a pivot. The box body 101 and the box door 102 are respectively provided with a first latch 103 and a first locking ring 104. The box body 101 is provided with a horizontal layer plate 105 and a vertical partition plate 106. The layer plate 105 and the partition plate 106 divide the box body 101 into several rows and columns of accommodating cavities 107 for storing sample boxes 200. The sample box 200 includes a sample box body 201 and an upper-opening sample box cover 202. The sample box body 201 and the sample box cover 202 are connected by a pivot. The sample box body 201 and the sample box cover 202 are respectively provided with a second lock 203 and a second lock ring 204. The sample box body 201 is provided with several rows of trapezoidal grooves 205 for connecting with the sample rack 300. The sample rack 300 is generally strip-shaped. The sample rack 300 has tube holes 301 on its upper part, which are the same number of rows as the trapezoidal grooves 205 in the sample box body 201, for accommodating sample tubes. The tube holes 301 are provided with elastic rubber plugs 302. The sample rack 300 has trapezoidal protrusions 303 on its lower part, which match the trapezoidal grooves 205 in the sample box body 201. The sample rack 300 has wing plates 304 on both sides, and the wing plates 304 are provided with labels 305 for positioning sample tubes.
[0005] Furthermore, a handle 108 is provided on one side of the box body 101.
[0006] Furthermore, a fixed suction cup 109 is provided on the upper part of the box body 101.
[0007] Furthermore, the box body 101, box door 102, layer plate 105 and partition plate 106 are made of stainless steel.
[0008] Furthermore, the sample box 200 and sample holder 300 are made of hard plastic.
[0009] This utility model has the following beneficial effects: 1. Not easy to tip over: The sample holder has elastic rubber plugs in the tube holes to fix the sample tubes. Even if the holder is tilted or overturned, the sample tubes can be fixed in their original positions.
[0010] 2. Convenient opening and closing of the lid: The box body and the door, as well as the sample box body and the sample box lid, are connected by a pivot, which can rotate freely 180°, making it convenient to open and close the lid.
[0011] 3. The sample box and the main body of the box are designed with a drawer-style connection, which facilitates cleaning, organization and de-icing.
[0012] 4. Extend the preservation time of strain biological characteristics: Each sample rack can store 10 specimens. Transferring 10 specimens together can shorten the storage time of strains in the freezer. Transferring them to a -80°C low-temperature freezer as soon as possible can extend the preservation time of strain characteristics, facilitate strain access, avoid repeated freeze-thaw cycles and multiple openings of the low-temperature freezer, extend the preservation time of strain biological characteristics, and reduce costs.
[0013] 5. Systematic storage: The strains are stored in a systematic and orderly manner by classification and partitioning according to their characteristics through a labeling system, which facilitates location and retrieval. The labeling system also facilitates statistics, allowing for real-time monitoring of strain usage and inventory, and making it easier to track the passage of quality control strains. This system also facilitates the management and preservation of strains, thus changing the problems of difficult statistics and haphazard storage in existing laboratories.
[0014] 6. By locking the outer box and sample box, the biosafety problem of double-locking for strain preservation in the field of microbiology is solved, avoiding strain loss, facilitating management, and making it suitable for most microbiology laboratories, while saving space.
