Polypropylene filter medium BIOTFFC

polyethersulfoneliquidmembrane

Overview
Ultrafiltration membrane cassettes package are a tangential flow membrane separation technology solution, widely used in pharmaceutical processes, particularly in downstream purification of biopharmaceuticals, including solution concentration, diafiltration, desalination, and separation and purification of components of varying molecular sizes.

Product summary
LABGENI TFF ultrafiltration membrane cassette package. Advanced automated packaging and an optimized dead-angle-free internal structure enable reliable rinsing and reduced fouling. Uses internationally recognized polyethersulfone (PES) membranes delivering high flux and retention, low protein adsorption, and broad temperature and pH compatibility.

Key features

• Molecular weight cutoffs available from 1 kDa to 1000 kDa.
• Six cassette sizes with identical flow channel length and height to enable linear scale-up from laboratory to pilot and production.
• Optimized automated packaging and dead-angle-free internal geometry for effective rinsing and low fouling.
• Adapter membrane closures compatible with mainstream membrane clamps; custom clamps available on request.

Typical application areas

• Biopharmaceutical downstream purification
• Solution concentration
• Diafiltration
• Desalination
• Separation and purification by molecular size

Advantages
LABGENI membrane cassettes provide consistent hydraulic geometry across sizes to support linear scale-up. PES membranes offer excellent flux/retention balance and low protein binding. Packaging and processing follow controlled quality systems suitable for bioprocess applications.

Adapter & closure
Adapter membrane closures are compatible with mainstream membrane clamps on the market. LABGENI can supply clamps meeting specified requirements.

Packaging & storage
Vacuum-packed in aluminum foil bags. PES membrane packages are preserved with 0.2N sodium hydroxide and 25% glycerol.
