GPES4722WS – 0.22 µm PES Membrane Filter, 47 mm

Description:
The GPES4722WS is a high-quality membrane disc filter featuring a hydrophilic PES (Polyethersulfone) membrane with a 0.22 µm pore size, designed for fast and sterile filtration of aqueous solutions. With a 47 mm diameter, this filter is ideal for laboratory-scale filtration, microbiological testing, and buffer/media preparation where high flow rates and low protein binding are essential.

Key Features:

• Membrane Material: PES (Polyethersulfone)
• Pore Size: 0.22 µm
• Diameter: 47 mm
• Format: Flat membrane disc (requires holder for use)
• Sterilization: Autoclavable at 121°C for 30 minutes
• Hydrophilic: Rapid wetting; no pre-wetting required
• Applications:
  • Sterile filtration of buffers, culture media, and reagents
  • Sample preparation in pharmaceutical and biotech labs
  • Filtration of protein-containing solutions with minimal binding
  • Microbiological quality control and bioburden reduction
• Compatibility: Suitable with vacuum or pressure filtration setups

A reliable and efficient membrane for sterile filtration in high-volume laboratory workflows.
