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

• Up to 3.5 times higher flow rates than competitive sterilizing grade filters
• Fully validated and integrity testable membrane for assurance of sterility
• Low binding for minimal product loss
• Single-use capsule format available with Pre-sterile version by Gamma-irradiation

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 minimize product loss due to adsorption.

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