Propor SG

PROPOR SG sterilising grade filters feature a patented, microbially retentive polyethersulphone membrane for fast, reliable and cost-effective sterile filtration of pharmaceutical fluids.

Propor SG

The asymmetric pore structure and high voids volume of the PROPOR SG membrane allow high throughputs and exceptionally high flow rates compared with competitive PES and alternative membranes. Low protein and preservative binding properties minimise product loss due to adsorption.

PROPOR SG filters are optimised for pharmaceutical processing. They have low extractable levels and broad chemical compatibility across the full pH range including organic solvents.

Features & Benefits

  • Up to 3.5 times higher flow rates than competitive sterilising grade filters
  • Fully validated and integrity testable membrane for assurance of sterility
  • Low binding for minimal product loss
  • MURUS and DEMICAPs can be gamma-irradiated and autoclaved
