Pura Disc FP 30mm CA Syringe Filter, 0.2um, Sterile, 50 Pk
Whatman SKU: 10462200

Whatman Puradisc Cellulose Acetate (CA) Syringe Filters, 0.2 µm, 30 mm, 50/Pk - 10462200

Whatman's filtration expertise, refined across a century-plus of disciplined manufacturing, has made its name synonymous with laboratory-grade quality worldwide. Sterilizing-grade retention is built into the membrane itself, clearing bacteria as the syringe pushes sample through. Cellulose acetate admits water-based reagents immediately, with no surfactant step and handles water-based samples and low-alcohol solutions. Polycarbonate construction handles routine aqueous sample matrices while standing up to rugged field and bench handling and sustains high operating pressures without deformation. Where bacterial contamination must stay out of the sample, the sub-micron pore rating clears it before the sample reaches the instrument.

Technical Specifications

• Clarifies aqueous HPLC mobile phases and injection samples ahead of column exposure.
• Cellulose acetate's open pore structure supports high flow rates at low operating pressure.
• Food-contact-approved composition supports clarification of wine, beer, juice, and dairy beverages
• Accepts gamma irradiation or ethylene oxide exposure as alternative sterilization methods to autoclaving
• Tolerates methanol and ethanol at typical laboratory working concentrations

Housing Specifications

• Gamma-stabilized housing resists radiation-induced embrittlement during terminal sterilization
• Rigid construction holds dimensional tolerance under filtration load
• High-impact-strength housing resists cracking under demanding handling
• Suited to aqueous samples, buffers, and reagents

Clarify your routine aqueous samples in a single pass and cut down on juggling multiple filter types at the bench. Consistent aqueous clarification clears particulates without slowing your bench routine across the buffers and reagents your day-to-day prep depends on. Ask about a quality certificate, lot documentation, or a blanket-order quote for your filtration order at any time.
