How does a Biobank work?

Biological samples are an important support for biodiversity research and protection, but the preservation of samples is not easy. It is necessary to provide them with a comfortable environment and maintain integrity, as well as biological activity and sample quantity.

The improved biobank based on the liquid nitrogen tank is very suitable, do you know how it works?

In fact, it is very different from the liquid nitrogen tank.

Conventional liquid nitrogen tanks directly store biological samples with liquid nitrogen at -196 °C, but the number is limited; The biobank, which uses liquid nitrogen indirectly, can store a large number of samples and the environment is safer.

The biobank places liquid nitrogen below the sample storage area, separated by a tray, with an evaporator at the bottom.

The liquid nitrogen flows through the evaporator to be vaporized, rises due to its light volume, and enters the sample storage space. The continuous nitrogen delivery in the lower part can not only maintain a low temperature environment, but also prevent liquid nitrogen from contacting the sample, avoiding pipe bursts and cross-contamination.

When the amount of liquid nitrogen at the bottom is insufficient, the rehydration device of the biobank starts, automatically replenishes, and stops when it reaches the preset position. Intelligent operation, no need to open the lid, stable internal

temperature, very comfortable for biological samples without being disturbed.

In addition, the biobank can also monitor the situation of the samples in real time, make temperature curve reports, abnormal alarms, etc. It is a good choice if you want to store a large number of biological samples for a long time.
