CryoBag Freezing Bags

OriGen CryoBags are used for cryopreserving tissues and cell cultures at any temperature, including direct immersion in liquid nitrogen.

CryoBags are made from a coextrusion of Kapton® and FEP films: the outer layer is Kapton, which is gas impermeable, making the bag ideal for direct immersion in liquid nitrogen, and the inner surface of the CryoBag is pure FEP, which has unsurpassed biocompatibility. Where immersion in vapour phase is required, a self-adhesive tape seal is available. When storing in the liquid phase, a standard bar heat seal is recommended. The bag itself is also silkscreened with a writing area.

Advantages of the CryoBag

  • Remains flexible with no significant decrease in mechanical strength at temperatures from -196°C to +200°C
  • Both layers are inert and contain no leachables or extractables
  • Notched for easier opening and square seals mean that the bag has a larger internal volume than a bag with chevron seals
