Sartoclean® GF | Sartoscale 47 | 0.8µm | 3pc.

Sartoclean® GF Adsorptive Prefilters

Sartoclean® GF filters combine cellulose acetate membranes with glass fiber adsorption to reduce colloids, lipids, and bioburden in biopharmaceutical liquids. High throughput and effective clarification support consistent processing and protection of downstream steps.

Key Features

• Glass Fiber Adsorption: Glass fiber fleece captures colloids and lipids, improving clarification and helping stabilize flow across the filtration cycle.
• Composite Membrane Design: Cellulose acetate membranes pair with glass fiber support to enhance contaminant removal and bioburden reduction in complex fluids.
• High Throughput Performance: Optimized construction maintains flow at relevant loadings, which supports shorter filtration cycles and efficient sizing.
• Robust Operation: Mechanical and thermal resilience supports operation at differential pressures up to 5 bar, aiding performance in demanding steps.
• Scalable Formats and Areas: Available in multiple formats to enable predictable transitions from development to production.
  

Applications

• Fermentation broths
• Serum
• Plasma
• Cell culture media
• Colloid and lipid containing solutions
  

Benefits

• Consistent Clarification: Effective removal of particulates, colloids, and lipids helps reduce turbidity and supports process consistency.
• Downstream Protection: Bioburden and colloid reduction help protect final sterilizing filters and equipment, supporting stable operation.
• Shorter Filtration Cycles: High throughput and appropriate sizing can reduce filter changeouts and time per batch, improving line utilization.
• PFAS: Made without intentionally using PFAS compounds.
• Predictable Scale-Up: Common materials and architecture across formats provide reproducible performance from screening to large-scale runs.
• Process Economy: Efficient contaminant removal and stable flow support lower overall filtration effort and help optimize cost per liter processed.
