PES MembraneCobetter 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.
Hydrophobic PTFE MembraneCobetter 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.
Oleophobic PTFE MembranesCobetter 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.
Hydrophilic PTFE MembranesCobetter hydrophilic PTFE (polytetrafluorethylene) membrane filter has a durable wide operating temperature range and resistance to the destructive effects of many chemicals. It can be used to filter aqueous fluids without prior wetting.
Hydrophilic PVDF MembraneCobetter 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.
Positively-charged PES MembraneCobetter 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.
