What is a cryotube?

A cryotube is a container used to store biological samples under ultra-low temperature conditions (usually -80℃ or even lower liquid nitrogen temperature).

Uses

Biological sample storage: widely used to store biological samples such as cells, tissues, blood, nucleic acids, etc. In the fields of medical research, biotechnology, and pharmaceuticals, cryotubes are important tools for preserving precious biological samples. For example, in the field of cell therapy, they are used to store processed cells for subsequent clinical applications; in genetic engineering, they can be used to preserve extracted nucleic acid samples.

Long-term preservation: Because ultra-low temperature environments can greatly slow down the metabolism and degradation process of biological samples, cryotubes can achieve long-term preservation of biological samples. Some samples can be stored for years or even decades at ultra-low temperatures without losing their biological activity.
