Cryopreservation bags are specialized single-use bags designed to freeze and store cells, biologics and biological samples at ultra-low temperatures. They protect valuable biological material during cryopreservation, cold-chain transport and long-term storage. Wuxi Harmake Technology Co., Ltd. manufactures cryopreservation bags for biopharmaceutical, cell therapy and laboratory applications.

 

 

What Is a Cryopreservation Bag?

 

A cryopreservation bag is a sterile flexible bag manufactured from film that remains strong and flexible at ultra-low temperatures, such as -80°C freezers or liquid nitrogen storage. It holds cell suspensions, vaccines and biologics securely during freezing and thawing while maintaining sample integrity and sterility.
