Sartocon® Self Contained Filter and Bag Loop Assemblies 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.

Item no.:  SFA-SUM1467921

Availability (ex works):  On Request


The gamma sterilized bag loop assembly consists of a Polyethersulfone membrane (PESU) self contained filter unit, tubing, four pressure domes, retentate and permeate flow meters, two valve bodies for back pressure control in the retentate and permeate line, perestaltic pump tubing and a 10 L recirculation bag including a thermowell and a vent filter.

Bag loop assemblies for the SARTOFLOW® Alpha plus SU 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 larger production scale filter cassettes, enabling linear scale-up to larger filter areas. The single use concept is an ideal choice for Contract Manufacturers, research and development applications and all companies with multiproduct through-put.
