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.
