Sartoguard GF Prefiltration Filters

Sartoguard GF filters provide efficient prefiltration for biopharmaceutical liquids, combining clarification and bioburden reduction in a scalable platform. A dual-layer Polyethersulfone (PES) membrane protected by glass fiber fleece delivers high throughput and reliable retention.

Key Features

• Dual-Layer Construction: PES membrane combined with a glass fiber fleece enhances particle loading capacity while maintaining reliable retention of fine particulates.
• Nominal Retention Ratings: Available in 0.1 µm and 0.2 µm nominal ratings to match clarification and bioburden control needs at different process steps.
• Defined Retention Performance: Typical log reduction value of 6 per cm² for defined microorganisms supports confident bioburden reduction in media and intermediates.
• Integrity Testable: Supports on-site diffusion and bubble point testing for straightforward qualification and routine release in development and production.
• Scalable Formats: Available in multiple formats to enable linear scale-up from process development to large-scale manufacturing.
  

Applications

• Prefiltration of Cell Culture Media
• Buffers
• Serum
• Ophthalmics
• Large Volume Parenterals; Colloid and lipid containing liquids
  

Benefits

• Effective Bioburden Control: Retention performance helps lower microbial load, supporting consistent processing and protecting your sterilizing-grade filters.
• Strong Clarification Capability: Dual-layer design with glass fiber fleece reduces turbidity and captures a wide particle size range to stabilize flow and reduce fouling.
• Shorter Filtration Cycles: High throughput supports reduced processing time and may lower filter count, contributing to efficient batch turnaround.
• PFAS: Made without intentionally using PFAS compounds.
• Consistent Scale-Up: Common materials and membrane architecture across formats provide predictable performance from laboratory screening to production scale.
