CellStor Freezing Bags are suitable for cryopreserving biological samples down to -196°C in both the liquid and vapour phases.

CellStor freezing bags are used to freeze and cryopreserve cells (primary cells and cell lines), and cellular components, blood and blood components, tissues, and other biological products such as vaccines, proteins, exosomes, etc. for use in various treatment modalities such as stem cell therapy, CAR-T cell therapy, NK cell therapy, gene therapy, tissue engineering, and regenerative medicine.

CellStor freezing bags are made up of special grade Ethylene-vinyl acetate (EVA), also known as polyolefin. They retain their flexibility even at freezing temperatures and have high puncture resistance.

CellStor freezing bags are resistant to gas and liquid permeation, they facilitate cross contamination-free storage and culture.
