0.22μM Hydrophilic Polyethersulfone PES Membrane With PP Or PET As Supporting Layer
Hydrophilic PES Membrane 0.22μm Pore Size, PP or PET Support Layer, Low Adsorption
The polyethersulfone (PES) microfiltration membrane adopts an asymmetric structure with uniform openings. Polyethersulfone has excellent heat resistance, physical and mechanical properties, insulation properties, etc. PES microfiltration membrane can ensure low protein adsorption and low dissolution characteristics during the filtration process.
Our company adopts proprietary membrane manufacturing technology to achieve the best combination of interception efficiency and flux through the control of micropores. The produced filter membrane has precise pore size control and reliable mechanical strength. All raw materials meet the standards and requirements of pharmaceutical grade filter membranes.
Product Advantages :
- Excellent natural hydrophilicity
- High porosity, ensuring maximum flux and flow rate;
- Excellent chemical resistance and heat resistance;
- Low dissolution, extremely low protein adsorption;
- Good mechanical strength and maintains parameter stability;
- High temperature steam sterilization, ethylene oxide sterilization γ sterilization
