These tank liners are single-use bags with an open top, designed to fit in cylindrical vessels.

• No cleaning after media preparation
• Medical grade, multi-layer film
• For bioprocess applications
• Delivered gamma irradiated and ready-to-use

These bags which have a bottom drain are used as a liner into a vessel to avoid cleaning of the vessel after media and buffer preparation. After installing the Tank Liner into a vessel and filling it with liquid, powder can be added to the vessel and the mixing process can start by using an overhead agitator. When mixing is finished, it’s possible to pump the mixed liquid into sterile bags by using a sterile filter in order to have sterile media and buffers.

Tank liners are made of a clean medical grade multi-layer film designed for bioprocess applications. The fluid contact layer is a medical grade LLDPE. To minimize gas diffusion, an EVOH layer is coextruded between the inner and outer layers. The outer, non-contact strength layer is formed from polyamide and is coextruded with polyethylene to create a bonding layer.
