AI Technical Summary

Technical Problem

Traditional test tubes are prone to rolling during slant culture preparation, which can deform the culture medium. Randomly placed stoppers can also lead to the growth of miscellaneous bacteria, affecting the accuracy and efficiency of experimental results.

Method used

Design a test tube rack for making slant culture media. It adopts an upper and lower box structure with stacked upper and lower boxes. Through the design of horizontal sliding connection and upper and lower grooves, it ensures that the slant area of ​​the test tubes is consistent and fixes the stopper in the upper box to avoid the growth of miscellaneous bacteria.

Benefits of technology

This achieves uniformity and stability of the slant area in test tubes, reduces the risk of contamination by other microorganisms, and improves the flexibility and efficiency of experiments.

Abstract

The utility model relates to the technical field of test tube racks, and particularly discloses a test tube rack capable of being used for manufacturing a slant culture medium. Comprising an upper box and a lower box which are stacked up and down, a plurality of first test tube holes are formed in the bottom of the upper box, and a pore plate is arranged at the top of the upper box and provided with a plurality of second test tube holes right opposite to the first test tube holes; a connecting structure is arranged between the upper box and the lower box for transverse sliding connection, a side opening is formed in one side of the upper box in the sliding direction, a plurality of upper grooves for positioning test tube bodies are formed in the edge of the bottom of the side opening, and a plurality of lower grooves for supporting the test tube bottoms are formed in the bottom of one side, opposite to the side opening, of the lower box. The relative position of the upper box and the lower box can be adjusted, the test tube rack can be used for manufacturing a slant culture medium through test tubes, the test tube rack can be formed by splicing the components when the slant culture medium does not need to be manufactured, and the conventional test tube placement requirement can be met, so that the flexibility and applicability of the test tube rack are improved; the test tube placement requirements under different experiment conditions can be better met.
