The single layer EVA/polyolefin film of the PureTain^® freezing bags contains no binders, agents, or adhesives and therefore offers excellent biocompatibility as a product contact material. The EVA combines high durability with excellent flexibility. The freezing bags are compatible with many cell preservation media such as DMSO/dextran, making them perfect for handling cell and gene therapy intermediates and products.

PureTain^® freezing bags are available in over 50 sizes available from 2 ml to 3 l. They can be custom-configured, e.g. in terms of the number of connections. Specifically designed for controlled freezing and thawing, their multi-compartment design minimizes fluid loss during transfer operations.
