Test-tube stand for batch inoculation in laboratory

Abstract

The invention relates to a test-tube stand for batch inoculation in a laboratory. A strain mother tube fixing bracket and a to-be-inoculated test-tube mounting bracket are fixed on a workbench, wherein the strain mother tube fixing bracket comprises a base, an upright post and a test-tube holder, a horizontal straight sliding chute is fixed longitudinally along the workbench and a straight sliding rail is placed in the straight sliding chute, the feed of the straight sliding rail is driven by the rotation of a rotary knob, a C-shaped rubber clamp for locking a to-be-inoculated test-tube is fixed on the straight sliding rail, a metal bellows for gripping test-tube plugs is fixed at one side of a vertical plate, a plurality of air outlets, which are distributed in a circular ring shape, are formed in the workbench, a hot wind bin, a heating bin and an air duct are located at the lower side of the workbench, a pinhole running from top to bottom is formed in the workbench and a needle body of an inoculating needle penetrates through the pinhole and is just located at a heating core area of a heating device. According to the test-tube stand disclosed by the invention, the test-tubes can be fixed in the test tube stand in batches and a plurality of test-tubes can be inoculated in a batch, and therefore, the efficiency is greatly improved.

Description

technical field [0001] The proposal relates to the technical field of laboratory equipment, in particular to a test tube rack for laboratory batch inoculation. Background technique [0002] At present, there is no batch inoculation test tube rack used in aseptic operation on the market. At present, manual operation is used, and an alcohol lamp is used to assist in creating a sterile environment. Mycelium or bacteria block, then cover with cotton plug, put it on the table, pick up the test tube to be inoculated, pull out the cotton plug, put the bacteria into the test tube to be inoculated, and then cover with the cotton plug. Batch inoculation is to repeat the above process. Low efficiency and unskilled operation keep the picked bacterial mass or hyphae and the test tube port where the cotton plug is removed away from the absolute sterile area created by the alcohol lamp, resulting in an increased chance of contamination. [0003] In the aseptic operation, the most importa...

AI Technical Summary

Problems solved by technology

The hyphae or bacteria blocks picked by the existing manual operation are exposed to the air for a long time, and the absolute sterile area created by the alcohol lamp is small, and it is easy to dissociate from this area, increasing the chance of contamination

[0005] (2) The alcohol lamp is easy to overturn during use, and the leakage of alcohol will cause fire and personal injury, and will also damage the experimental materials

[0006] (3) In the process of batch inoculation, it is necessary to repeatedly take and place the parent tube of the strain and the test tube to be inoculated, and the efficiency is low
