CryoPAC Series Freezing Bag

The CryoPAC Freezing Bags are designed, produced and verified for a single cycle of freezing, cryogenic storage 

(down to -196°C) and thawing (at +37°C) of biological products. 

Each CryoPAC freezing bag is supplied with an overwrap bag, a set of integrated filling assembly and various of 

connection ports. The freezing bag main body and its overwrap bag are made of EVA, which has been proved to 

be durable for long term cryogenic preservation in liquid nitrogen. 

Various sizes with different nominal volumes are available: 25ml, 50ml, 250ml, 500ml & 750ml. Recommended 

filling volume from 5ml to 190ml. 


Sterile

Each CryoPAC freezing bag, including corresponding overwrap bag, is individually packed and sterilized by electron-beam irradiation. The outer packaging can be disinfected for easy clean -room handling. This helps to maintain a sterile workflow from cell collection to storage and subsequent thawing.

Validation

Extensive validation testing was conducted to guarantee safety of CryoPAC freezing bags, such as: Irradiation sterilization/Physics and Chemistry/Biocompatibility/Extractables/Repeated freezing and thawing/Transportation
