LabExact Cellulose Acetate (CA) Syringe Filters, 0.22 µm, 13 mm, 100/Pk - LE-IWT-ES10088

A sterilizing-grade syringe filter carries manufacturer bacterial retention testing built into the design, giving analysts documented sterile-grade performance without repeating that testing in-house for the format. The cellulose acetate surface stays smooth with low extractable background while staying stable across pH 4 to 8 and stops bacterial passage even at its smallest pore rating. Polypropylene housing is factory-sterilized and packaged to preserve that state until use while pressing snugly against the membrane during the pass and maintains a low-dead-volume internal flow path. For workflows requiring validated sterile-grade performance, point-of-use retention meets it without a separate sterilization step.

Membrane Characteristics

• Stable in aqueous saline, buffer, and protein solution matrices
• No alcohol pre-wetting required before aqueous sample introduction
• Dilute samples retain their true, unadsorbed concentration through the membrane
• Smooth membrane face with even pore distribution across the active filtration area
• Retains particles at the membrane surface instead of throughout its thickness

Housing Characteristics

• Polypropylene density near 0.90 g/cm3 keeps housing weight low relative to denser engineering plastics
• The seal formed against the membrane blocks bypass at rated operating pressure
• Polypropylene housing tolerates ethylene oxide gas sterilization cycles without softening or dimensional distortion
• Low moisture absorption keeps the housing dimensionally stable through humid storage and shipping

Juggling several filter types for one routine clarification eats up your bench time. General-purpose aqueous filtration supports the sample types you handle every day across your water-analysis and general analytical workflows.
