Answer:Omega polyethersulfone (PES), 300 kDa nominal MWCO and 0.1 m² effective filtration area.
Answer:It is a nominal molecular-weight separation characteristic for ultrafiltration, not a particle diameter or a 300 µm pore rating.
Answer:Tangential flow concentration, diafiltration and separation of relatively large biomolecular assemblies, subject to experimentally verified recovery and retention.
Pall T-Series Centramate Omega PES is a tangential flow filtration cassette designed for macromolecular separation, concentration and diafiltration at laboratory-development and pilot scales. The membrane uses polyethersulfone (PES) with a 300 kDa nominal molecular weight cutoff and 0.1 m² effective filtration area. Its relatively open ultrafiltration cutoff is appropriate for processes targeting larger retained species while allowing smaller soluble components to pass, subject to membrane interactions and feed composition. The Omega PES structure combines low protein binding with a chemically durable filtration surface, supporting systematic process screening. In tangential flow operation, the recirculating feed sweeps the membrane surface while permeate is collected separately. Recovery, selectivity and achievable concentration depend on transmembrane pressure, crossflow, temperature and product characteristics. Confirm cassette-holder compatibility and validated operating limits before scaling a process. The 300 kDa cutoff is a molecular weight designation, not a 300 µm pore size.
