Overview
Merck process containers are single-use flexible containers designed specifically for bioprocessing, storage and transport of biopharmaceutical fluids in sterile conditions. They are free of animal derived components.
Product Description
SureFlex process container film are manufactured utilizing a high purity, medical grade composite film designed to provide strength, flexibility (with maximum resistance to flex-crack), excellent gas barrier performance and inert contact. The fluid contact material is ethylene vinyl acetate (EVA). The gas barrier is made of polyethylene vinyl alcoholcopolymers (EVOH). The outer layer is made of LLDPE.
