The generation of lyophilization tubes edit most of the laboratories in China are currently experimenters make their own strain preservation tubes, which not only increase the work intensity, but also due to various conditions, the strain preservation effect can not always be satisfactory. The creation of strain preservation tubes has made this extremely easy. Freeze storage tube is the common name for the commercial name of strain storage tube.

Generation, composition and use of lyophilization tubes

The generation of lyophilization tubes edit most of the laboratories in China are currently experimenters make their own strain preservation tubes, which not only increase the work intensity, but also due to various conditions, the strain preservation effect can not always be satisfactory. The creation of strain preservation tubes has made this extremely easy. Freeze tube is the common name of commercial strain preservation tube.

The composition of the lyophilization tube edit strain preservation tube mainly consists of three parts: preservation solution, preservation tube and small porcelain beads, it is a kind of laboratory preservation strain container, used for the preservation or transfer of strain, generally strain preservation tube has 25 small porcelain beads inside for the adsorption and preservation of bacteria. In the process of use, the bacteria will be inoculated in the preservation tube, placed in -20℃ or -80℃ environment can be stored for a long time. (-20℃ can be stored for one year, -80℃ can be stored for two years).

Steps of using lyophilization tubes edit

(1) Pick a fresh culture from the pure culture of bacteria to make a bacterial suspension of about 3-4 Mack's turbidity and inoculate with the strain storage tube.

(2) Tighten the tube and turn it back and forth 4-5 times to emulsify the bacteria, without shaking it.

(3) Put the storage tube into the refrigerator (-20℃-70℃).
