A strain preservation tube

Abstract

The invention discloses a strain preservation tube, and belongs to the technical field of microorganism preservation devices. An inoculating loop arranged in a tube body is fixed in a tube cap of the provided preservation tube, the inoculating loop in the preservation tube can be directly used for streak inoculation when a preserved strain is taken out for inoculation, other inoculating loops are not required, and the inoculating loop is not required to be sterilized, so that time and labor are saved, and the possibility of strain pollution is reduced greatly; and a mushroom-shaped bulge is formed in the top of the tube cap, so that the preservation tube can be conveniently taken out of and put in a preservation box.

Description

technical field [0001] The invention belongs to the technical field of microorganism preservation devices, in particular to a strain preservation tube. Background technique [0002] In genetic engineering, it is necessary to store the constructed strains at low temperature or even ultra-low temperature (-80°C); due to the long period of constructing a strain that can achieve the expected effect, it is often necessary to store some bacteria in the construction process at low temperature (eg -20°C) for storage. [0003] In practice, it is often necessary to inoculate and activate these cryopreserved bacteria for the next step in genetic engineering, or to inoculate and activate cryopreserved strains for amplified production. During the inoculation operation, an inoculation loop is often used for inoculation. If the inoculation loop is not sterilized sufficiently, precious bacteria will be contaminated, which will cause a very large loss. Or, in order to fully sterilize t...

AI Technical Summary

Problems solved by technology

In the inoculation operation, the inoculation loop is often used for inoculation. If the inoculation loop is not sterilized sufficiently, precious bacteria will be contaminated, which will cause a very large loss

Alternatively, in order to fully sterilize the inoculating loop, additional operating time is often required, and if different preserved bacteria are inoculated at the same time, it takes more time and the chance of cross-contamination is greater

[0004] In addition, the bacteria storage tubes are generally placed in a storage box and then stored in a refrigerator. In order to save space, the storage tubes are arranged closely in the storage box, and because of freezing, it is often difficult for operators to put The preserved strains are taken out of the preservation box
