Introduction to Precision Cryogenic Storage

When your cell therapy laboratory or biobank needs to preserve biological products through a complete freeze-thaw cycle, the container you choose is critical. A bag that cracks at cryogenic temperatures, leaks during thawing, or fails to maintain sterility can destroy irreplaceable cell samples, invalidate batch records, and cost you valuable time and resources.

The CryoPAC Series Freezing Bag is engineered to eliminate these risks. As a cornerstone of the CryoPAC Series Freezing Bag range, this product is built for cell therapy laboratories, biobanks, and research facilities that require uncompromising performance for cryogenic storage at temperatures down to -196°C and thawing at +37°C. This CryoPAC Series Freezing Bag provides a reliable, validated container for your most critical biological products, with sterile packaging and durable EVA construction. We understand that in your line of work, sample integrity is not just a feature—it is a necessity.
