IV Filter Membranes 

Optimally-designed Membranes Help Enhance Filter Performance 


-High-Flow Fluids Membrane (PES) 0.2µm/1.2µm /5µm 

Highly asymmetric structure provides excellent flow rate (30% faster than competitor membranes) and longer filter life 

Extremely low drug adsorption 

Biocompatibility certified 


-Bacterial Air Vent Membrane (PTFE) 0.02µm/0.03µm 

Eliminates the air quickly with minimal priming time 

High water resistance, no leakage 

Excellent sealing capability with filter housing 

Compatible with lipids and alcohol-based solutions (oleophobic version)

  • Positively-charged PVDF Membrane Cobetter hydrophilic PVDF membrane is available in 3 versions: low binding, positively charged and high binding type. The membrane is produced with high porosity and optimized porous structure, offering competitive performance for your products. The low binding type is ideal for clarification and sterile filtration of bio-pharmaceutical fluids. The high binding type is an transfer membrane for protein blotting applications. The positively charged type has excellent endotoxin removal efficiency,

  • Hydrophobic PTFE Membrane Cobetter Hydrophobic PTFE membrane is made from pure PTFE membrane bonded to a polypropylene support. The extreme chemical compatibility (pH 1-14) makes them very useful for the filtration of solvents and acids or other aggressive chemicals, for which other membrane filter types are unsuitable. Due to their hydrophobic characteristics, they must be pre-wet with a solvent such as ethanol or methanol before the filtration of aqueous solutions.
