CryoMACS® Freezing Bags consist of a freezing bag and a corresponding overwrap bag. Each freezing bag with its overwrap bag is individually packed and sterilized. An additional outer package can be disinfected. The filled freezing bag with its overwrap bag fit into the relating storage cassette. Both the freezing bag and the overwrap bag are made of EVA (ethylene vinyl acetate) tubular film.
The freezing bag is equipped with extra long EVA tubing for drawing quality control samples out of heat-sealed tube sections. The tubing is provided with luer connectors, roller clamps and an injection port. The EVA tubing and injection port are DMSO-resistant. Two ports with sealed, twist-off protective caps minimise the risk of nitrogen ingress into these ports. Each CryoMACS® Freezing Bag includes a label pouch and the imprinted lot number. Available volumes range from 50 to 1000 mL (recommended fill volumes 20 to 270 mL).
