Pura Disc FP 30mm CA Syringe Filter, 0.2um, Sterile, 50 Pk
Whatman SKU: 10462205

Whatman Puradisc Cellulose Acetate (CA) Syringe Filters, 0.2 µm, 30 mm, 50/Pk - 10462205

Whatman draws on Cytiva's broader manufacturing oversight while continuing a legacy of filtration work that touches laboratory research, environmental monitoring, and industrial processing alike. A syringe-mounted membrane at a sterilizing-grade pore rating clears microbial contamination from the sample stream. Cellulose acetate binds BSA at 3.8 micrograms per square centimeter while staying smooth with low extractable background and stops bacterial passage even at its smallest pore rating. The polycarbonate housing sustains high operating pressures without deformation and suits aqueous samples, buffers, and reagents. Where bacterial contamination must stay out of the sample, the sub-micron pore rating clears it before the sample reaches the instrument.

Technical Specifications

• Rated pore sizes of 0.22 micron and below block bacteria reliably
• Accepts gamma irradiation or ethylene oxide exposure as alternative sterilization methods to autoclaving
• Food-contact-approved composition supports clarification of wine, beer, juice, and dairy beverages
• Naturally hydrophilic surface wets readily with aqueous samples
• Cellulose acetate's open pore structure supports high flow rates at low operating pressure.

Housing Specifications

• Gamma-stabilized housing resists radiation-induced embrittlement during terminal sterilization
• High-impact-strength housing resists cracking under demanding handling
• Creep resistance keeps the polycarbonate housing seal secure under sustained mechanical load
• Suited to aqueous samples, buffers, and reagents

A clean particulate separation keeps your aqueous sample preparation dependable. General-purpose aqueous filtration supports the sample types you handle every day across your water-analysis and general analytical workflows.
