Cryogenics is the branch of physics that deals with the production and effects of very low temperatures. The process of cryogenics involves cooling materials to temperatures below -150°C using liquid nitrogen or other cryogenic fluids. This process has many practical applications, including preserving biological samples in cryogenic vials.
Cryogenic vials are specialized containers designed to store biological materials at shallow temperatures, typically below -150°C. They are made of materials that can withstand extreme temperatures and are designed to prevent contamination of the sample. Cryogenic vials are often used in medical research and biotechnology to store cells, tissues, and other biological materials for long-term preservation. Filling cryogenic vials with biological samples typically involves pipetting the sample into the vial and then immediately placing it into a container filled with liquid nitrogen or another cryogenic fluid for storage.
