Special test tube rack for preparing slant test tube culture medium

Abstract

The invention discloses a special test tube rack for preparing a slant test tube culture medium. The special test tube rack comprises a plurality of grid plates which are arranged in parallel from bottom to top and used for bearing and fixing test tubes, the device further comprises a plurality of parallel supports, the supports and the grid plate form a parallelogram mechanism, and parallelogram mechanism shaping assemblies are assembled on the connecting portions of the supports and the grid plate. The special test tube rack for preparing the slant test tube culture medium integrates a test tube rack, a sterilization basket and a slant cooling rack, so that repeated movement of test tubes in experimental operation can be avoided, and batch treatment and batch operation of the test tubes are realized; test tubes are effectively fixed during sterilization, and experiment safety is guaranteed; the inclination angle of the test tube can be set during cooling, vertical space is fully utilized, and operation table space is saved.

Description

technical field [0001] The invention belongs to the field of biological experiment equipment and relates to a test tube rack, in particular to a special test tube rack for making inclined test tube medium. Background technique [0002] The slant medium is a form of solid medium; when it is produced, it is quantitatively dispensed into test tubes while it is hot, and solidified into a slant, which is called a slant medium, which is used for the expansion of strains and the preservation of strains. The general process of configuring test tube slant culture medium in the laboratory is: put the subpackaged test tubes on the test tube rack, then bundle the test tubes into bundles and place them in the sterilization basket, and spread the test tubes obliquely on the test bench while they are hot after sterilization , and wait for cooling. In the process of realizing the present invention, the inventor has found that there is at least one problem in the following technical problem...

AI Technical Summary

Problems solved by technology

[0003] 1. The test tube needs to be moved repeatedly, which is time-consuming and laborious;

[0004] 2. The test tubes in the sterilization basket are easy to dump and cause danger;

[0005] 3. Putting it while it is hot after sterilization may easily cause burns to the experimenters;

[0006] 4. It takes up a lot of space on the table, and the test tube is easy to roll off

Although this test tube rack can avoid the problem that the test tubes in the sterilization basket are easy to fall and cause danger, and the corresponding holes in the test tube rack constitute the channel for the steam circulation around the test tubes in the sterilizer when the test tube rack is sterilized, which ensures the sterilization to a certain extent. But the core purpose of this test tube rack is only to sterilize the medium, and it does not pay attention to the problems that need to be paid attention to when placing the slant medium after sterilization

Based on the prior art of test tube racks used in high-pressure steam sterilizers, there are also complex structures, interlayer steam flow blocking effects, inconvenient putting / taking test tube racks, and easy placement of test tube racks after sterilization may cause burns to experimenters , Inconvenient for slope cooling and other technical problems
