Cryopreservation Bags

Cryopreservation Bags allow for durable, transparent, and flexible storage down to liquid nitrogen temperatures. Traditionally featuring at least one PVC tubing length for sterile docking, the unique bag design allows for closed system processing.

The KryoSure® “F” bags use an untreated form of FEP film, include label pockets for identification, and offer FEP port covers for additional protection during cryopreservation.

The bags are also designed with rounded inside corners to reduce the risk of ice points that may cause damage.

KryoSure FEP overwraps and sterility covers can be used in addition to the cryopreservation bags.

Cryopreservation Bags – Key Features

Exit Port: FEP, ISO compliant spike port with septum. Protected from external contamination by an integral tear-open, tamper-evident cover.

Inlet Line: 4mm PVC tubing with a clamp. This can be removed prior to cryopreservation.

Identification: ISBT 128 compliant label pocket as part of bag design. Serial numbers are engraved into the label pocket and etched into the fill tube in three places providing unalterable segments for cross-identification.

Other types of ports, tubing and connections are available and can be customised to suit your needs.
