XINNA 's Genflow® PES microporous filtration membranes utilize an asymmetric structure with uniform openings. The material itself possesses excellent heat resistance, physical mechanical properties, and insulating performance. PES microporous filtration membranes feature low protein adsorption and low leaching during the filtration process.The produced filtration membranes have precise pore size control and reliable mechanical strength. All raw materials meet the standards and requirements of pharmaceutical-grade filtration membranes.

Medical Application :IV filter's self air-stop filtration membrane :
XINNA's IV and liquid filter membrane is made of PES, which inherently has low protein adsorptionand low extraction characteristics.
lts featured asymmetric structure allows high flow rate, filtration efficiency and dirt holding capacity.
A pioneering sulfonation treatment makes the hydrophilicity of our PEs more unifom which promises better hydrophilic performance and higher flow rates in gravity infusion applications as compared to conventional PES from other competitors.
Other applications
- Conventional filtration
- Sterile filtration
- Biopharmaceuticals
- Bacterial isolation
