Easily identified strain preservation tube

Abstract

The invention provides an easily identified strain preservation tube and belongs to the technical field of microorganism preservation devices. An inoculating loop in a tube body is fixed in a tube cover of the preservation tube; when being taken out and inoculated, a preserved strain is subjected to streak inoculation by the inoculating loop directly without other inoculating loops, and the inoculating loop does not need to be sterilized, so that the time and the labor are saved and the probability of pollution to the strain is greatly reduced; a frosted surface is arranged at the top of the tube cover of the preservation tube, so that the strain can be conveniently marked by a marking pen or a label, and strains required to be taken out also can be conveniently identified when preservation tubes are closely arranged in a preservation box.

Description

technical field [0001] The invention belongs to the technical field of microorganism preservation devices, in particular to an easily identifiable 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 with the expected effect, it is often necessary to store some bacteria in the construction process at low temperature. In practice, it is often necessary to inoculate and activate these low-temperature-preserved bacteria or inoculate and scale up production. An inoculation loop is often used for inoculation during inoculation. If the inoculation loop is not sterilized sufficiently, precious bacteria will be contaminated, which will cause cause very large losses. Or, in order to fully sterilize the inoculating loop, additional operating time is often required. If different preserved bacteria are ...

Problems solved by technology

In practice, it is often necessary to inoculate and activate these low-temperature-preserved bacteria or inoculate and scale up production. An inoculation loop is often used for inoculation during inoculation. If the inoculation loop is not sterilized sufficiently, precious bacteria will be contaminated, which will cause cause great 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 contamination is greater
