Pura Disc FP 30mm CA Syringe Filter, 0.45um, Sterile, 50 Pk
Whatman SKU: 10462601

Whatman Puradisc Cellulose Acetate (CA) Syringe Filters, 0.45 µm, 30 mm, 50/Pk - 10462601

Whatman's established manufacturing platform delivers the consistency and lot-level documentation that analytical laboratories require. Syringe filters give the analyst a single-use device for clarifying samples right at the bench. Cellulose acetate suits aqueous solutions, buffers, and alcohols while delivering absolute particle retention at the rated pore size and minimizes protein binding for high analyte recovery. High-strength polycarbonate construction resists damage during demanding use and prevents sample bypass under rated operating pressure. Where small-volume samples must reach the instrument clean, syringe filtration clears particulates in a single pass.

Technical Specifications

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

Housing Specifications

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

Upstream clarification pays for itself by keeping your columns clear and your analytical day on schedule. Upstream sample clarification keeps your separations clean and reproducible so your filtrate reaches the column clean.
