  • Flexibility

    The CryoStore FLEX Bag can be filled and sealed into separate 4-6ml chambers for flexible utilization post-thaw. Depending on the number of cells a patient needs, a variable number of compartments can be utilized. The FLEX bag is designed for scalable dosing, and the bag segments can be used to increase doses incrementally.

  • Durability

    The CryoStore FLEX Bag is made of the same robust EVA material as our existing industry-preferred OriGen Biomedical CryoStore Bags, known for their durability proven through validation and customer success.

  • Representative

    Cell products frozen into the CryoStore FLEX bag will be contacting the same materials at similar freeze thicknesses as cell products frozen in larger CryoStore bags. The FLEX bag is a representative sample of the contents of a CryoStore final cell product bag that can be used for quality assurance testing and dosing.

  • Less Equipment

    FLEX Bags fit into the same size cassette as a CryoStore CS50 bag allowing for cold storage next to the final product and eliminating the need for cryovials and cold vial storage. It can be stored in the same rack and same tank as the final cell product.

Will freezing bags break or fracture when impacted, dropped, etc. while frozen?

All plastics have a glass transition temperature unique to the identity and grade of polymer that makes up the plastic (it varies but is  -65C to -150C for our materials). Above this temperature, the bags are flexible. However, once the bag is cooled below its glass transition temperature, the films lose their plasticity. Any impact, pinch, cut, etc. can result in a clean fracture that radiates from the point of impact, akin to broken glass. Please see our white paper on How to Prevent Freezing Bag Breaks for more information.
