2） Product Overview

Polyethersulfone (PES) membrane filters feature ultra-high flow rates and low molecular affinity. They barely adsorb proteins and macromolecules during filtration to minimize sample loss.
The inherent hydrophilic property eliminates the need for pre-wetting before filtering aqueous samples.

 

3） Key Features

  • Outstanding thermal and chemical resistance
  • Symmetric pore structure delivers exceptional fast flow rates
  • Ultra-low protein adsorption, ideal for protein solutions and aqueous sample filtration
  • Minimal extractable substances, perfectly suited for environmental testing

4） Applications

Benefiting from high throughput and low adsorption, PES membranes are adopted in pharmaceutical production for sterile filtration of injection solutions, and in biotech labs for cell culture medium filtration.
In general lab research, PES filters intercept fine particles to safeguard precision analytical instruments such as chromatographs from contamination.
