The gamma sterilized loop assembly consists of a Polyethersulfone membrane (PESU) self contained filter unit, two pressure domes, a TMP control pinch valve, a disposable pump head and tubing with Opta^® connectors. Feed and permeate lines are color coded.

Filter Loop assemblies for the FlexAct^® UD system are supplied sterile and ready to use. Due to the fully enclosed design the assembly is well suited for vaccine, recombinant protein and highly toxic ADC production. All product wetted parts of the system are supplied sterile and made from single use components. The system is suitable for use in cGMP environments for process development, clinical trials and for small-scale production batches. The cassette is designed with the same hydrodynamic flow path as our Sartocon^® Slice Self Contained device, enabling linear scale-up from smaller filter areas. The single use concept is an ideal choice for Contract Manufacturers, research and development applications and all companies with multiproduct through-put.
