• 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,
  • Hydrophilic PVDF Membrane Cobetter modified hydrophilic PVDF (Polyvinylidene Difluoride) membrane filter has excellent water wettability, providing high flow rate. PVDF membranes are naturally hydrophobic but are modified to a hydrophilic nature. Useful for a wide range of applications, both aqueous and non-aggressive solvent-based. These membranes are typically low protein binding and are frequently used for sterilizing filtration.

  • 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.
  • Hydrophobic and Oleophobic PES Membrane Cobetter polyethersulfone (PES) membrane is made of a modified polyethersulfone polymer cast. The optimized asymmetric structure, enhanced hydrophilicity and high porosity provides extraordinary high flow rate and contaminants retention capacity. The product uniformity results in consistent filtration performance.
