Pura Disc FP 30mm CA Syringe Filter, 0.2um, Nonsterile, 100/Pk
Whatman SKU: 10462710

Whatman Puradisc Cellulose Acetate (CA) Syringe Filters, 0.2 µm, 30 mm, 100/Pk - 10462710

Whatman's established manufacturing platform delivers the consistency and lot-level documentation that analytical laboratories require. Under hand pressure from the syringe, the membrane captures particulates as the sample passes through. Cellulose acetate delivers sterile-grade retention at the rated sub-micron pore size while staying stable across the pH 4 to 8 range and wets easily with aqueous buffers. The polycarbonate housing suits aqueous samples, buffers, and reagents while sustaining high operating pressures without deformation and holds a reliable seal against the membrane edge. When chromatographic methods demand particle-free injections, point-of-use syringe filtration clarifies the sample before it reaches the column.

Technical Specifications

• Sterile-grade retention at sub-micron pore sizes
• Very low protein binding supports high recovery of dilute 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

• Suited to aqueous samples, buffers, and reagents
• 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

Removing particulates from your buffers and mobile phases extends column life and keeps your baselines steady. Reliable particulate removal protects your instruments and your data so column life and baseline stability stay predictable.
