Sartobran® P

Sartobran® P 0.2 and 0.45 µm filters

Sartobran® P filters combine cellulose acetate membranes with low adsorption to support high product recovery across vaccine, blood and plasma, and biopharmaceutical processes.

Key Features

• Low-Adsorption Membrane: Cellulose acetate minimizes unspecific binding to help protect yield and support consistent recovery of valuable proteins and excipients.
• Gentle To Proteins: Flow characteristics and membrane properties help maintain the structure of large, shear‑sensitive proteins for reliable process performance.
• Two Retention Ratings: 0.2 µm for sterilizing-grade filtration and 0.45 µm for bioburden and particle reduction, enabling step-appropriate selection in upstream and final steps.
• Scalable Portfolio: Sartoscales, Capsules, Midicaps®, Maxicaps®, and cartridges provide a common platform that supports linear scale-up from process development to commercial production.
• Process Compatibility: Operates in the pH 4–8 range typical for many formulation buffers and process fluids, broadening applicability across unit operations.
  

Applications

• Coagulation Factors, Albumin, IgG
• Bacterial and Viral Vaccines
• Bioprocessed pharmaceuticals
• Intermediate and purified protein solutions
• Biological fluids
• Fluids containing preservatives
  

Benefits

• High Product Recovery: Very low unspecific adsorption helps reduce product loss, supporting high yields in vaccines, blood and plasma, and biopharmaceutical processes.
• Consistent Sterile Performance: The 0.2 µm grade is validated as sterilizing-grade and supports reliable bacterial retention in critical steps.
• Efficient Bioburden Reduction: The 0.45 µm grade reduces bioburden and particles upstream to help protect final sterilizing filters and downstream equipment.
• PFAS: Made without intentionally using PFAS compounds.
