Pura Disc FP 30mm CA Syringe Filter, 0.2um, Nonsterile, 50 Pk
Whatman SKU: 10462701

Whatman Puradisc Cellulose Acetate (CA) Syringe Filters, 0.2 µm, 30 mm, 50/Pk - 10462701

Whatman's expertise in cellulose, glass fiber, and polymeric membrane production guides material selection and quality control. Sample preparation for chromatography often ends with a syringe filter on the path to the vial. Low-extractable cellulose acetate keeps filtrate clean ahead of analysis and keeps protein adsorption very low across the run. The polycarbonate housing supports everyday aqueous filtration workflows and stands up to rugged field and bench handling. 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
• Very low protein binding supports high recovery of dilute samples
• Sterile-grade retention at sub-micron pore sizes
• Absolute pore-size rating gives consistent retention across protocols
• Naturally hydrophilic surface wets readily with aqueous samples

Housing Specifications

• Reliable housing-to-membrane seal prevents bypass at rated pressure
• Suited to aqueous samples, buffers, and reagents
• 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. Upstream buffer clarification keeps avoidable particulates out of your flow path before they reach the column inlet or detector.
