Parker´s PureTain^® freezing bags ensure protection of product integrity during cryo-preservation and low-temperature storage. The single layer EVA/polyolefin film contains no binders, agents, or adhesives, providing excellent biocompatibility as a product contact material. The EVA film is highly durable with excellent flexibility. Compatible with a large number of cell preservation media such as DMSO/Dextran, the freezing bags are a perfect fit for handling valuable cell and gene therapy intermediates and products.

PureTain^® freezing bags are highly modular with over 50 sizes available from 2 ml to 3 l. Specifically designed for controlled freezing and thawing, their multi-compartment design minimizes fluid loss during transfer operations.

Product Benefits:

• Safe storage down to -196 °C due to flexible and highly durable single-layer EVA film

• Clear product visibility due to very good film transparency

• Wide range of size configurations available, from 2 ml to 3 l

• Maximum sampling efficiency due to multi-compartment design for easy distribution of product into smaller and larger bags in one filling operation

• Advanced bag design with minimized dead spaces to prevent inhomogeneous product freezing during cryo-conservation

• Open architecture to create the perfect freezing bag system, e.g., with overmolded fluid transfer lines and needle-free connection options

• All materials are TSE/BSE-free and meet USP Class 6

Range of Application:

• Single-use systems for biopharma processing.

• Freezing and storing of cells
