PESS - Polyethersulphone (PES) Cartridge Filter
Masterfilter PESS filter cartridges manufactured with perfectly hydrophilic polyether sulfone symmetric membranes are specially designed to provide high flowrate with secure and reliable removal of spoilage microorganisms. Its unique construction structure allows optimal sterilisation performances of a wide range of fluids. Good inertia and low protein binding of PESS polyether sulfone membrane ensures perfect transmission of active ingredients.
Features
- Low diffusion flow
- Inherently hydrophilic PES membrane
- High surface area provides excellent flow rates and extended service life while maintaining high bacteria removal efficiency
- Low protein binding"
