Description

Multifunctional inclined plane test tube placing frame

Technical Field

The utility model relates to an experimental device field especially relates to a frame is put to multi-functional slope test tube.

Background

The culture medium in a solid state at a general culture temperature is called a solid culture medium, and the solid culture medium is in the form of a flat plate, a test tube slant and a submerged culture medium, wherein the test tube slant is mainly suitable for pure culture.

In the traditional process of manufacturing the test tube slant culture medium, after the culture solution in the test tube is sterilized at high temperature, the slant is arranged for condensation. The inventor finds that in the process, because the temperature of the wall of the test tube is high, liquid in the test tube flows very easily, the inclined plane inclination angle is not easy to meet the standard in the placing process, and the inclined plane culture medium is discarded due to the fact that a cotton plug stained on the top of the test tube is easy to occur. If the inclined angle of the inclined plane is not standard, the liquid surface is easy to cause pollution when the distance from the pipe orifice is too short, and the hypha growth quantity is too small when the distance is too long, so that the microbial bacterium preparation efficiency is reduced.

In addition, due to the limitation of seasonal factors, in the process of rapidly cooling the slant culture medium after high-temperature sterilization, if the external temperature is too low, the temperature in the process of solidifying the culture medium is too fast, a large amount of condensed water can be generated on the test tube wall above the slant, the generation of the condensed water is easy to promote the germination of mixed bacteria, and the water content of the culture medium is reduced, so that microorganisms after inoculation are polluted or grow badly.
