Pura Disc FP 30mm CA Syringe Filter, 0.45um, Sterile, 100/Pk
Whatman SKU: 10462610

Whatman Puradisc Cellulose Acetate (CA) Syringe Filters, 0.45 µm, 30 mm, 100/Pk - 10462610

Whatman's brand recognition and documented performance history support specification in standardized analytical methods. Under hand pressure from the syringe, the membrane captures particulates as the sample passes through. Naturally hydrophilic cellulose acetate wets easily with aqueous samples while preserving dilute proteins in the filtrate and stays smooth with low extractable background. The polycarbonate housing supports everyday aqueous filtration workflows while withstanding impact and handling without cracking and supports demanding high-pressure filtration. Where small-volume samples must reach the instrument clean, syringe filtration clears particulates in a single pass.

Technical Specifications

• Very low protein binding supports high recovery of dilute samples
• Naturally hydrophilic surface wets readily with aqueous samples
• Smooth surface with low extractables and a uniform pore structure
• Absolute pore-size rating gives consistent retention across protocols
• Stable with aqueous solutions, buffers, and alcohols across pH 4 to 8

Housing Specifications

• High-impact-strength housing resists cracking under demanding handling
• Reliable housing-to-membrane seal prevents bypass at rated pressure
• Suited to aqueous samples, buffers, and reagents
• Sustains high operating pressures without deformation

Clarify your routine aqueous samples in a single pass and cut down on juggling multiple filter types at the bench. Consistent aqueous clarification keeps your sample preparation moving across the buffers and reagents your methods rely on.
