Pura Disc FP 30mm CA Syringe Filter, 0.2um, Nonsterile, 500 Pk
Whatman SKU: 10462700

Whatman Puradisc Cellulose Acetate (CA) Syringe Filters, 0.2 µm, 30 mm, 500/Pk - 10462700

Whatman applies over a century of filtration media expertise, manufacturing under the quality standards that established its products as global laboratory references. A syringe filter holds its membrane in a leak-tight housing for clarification at the bench. Naturally hydrophilic cellulose acetate wets easily with aqueous samples and handles water-based samples and low-alcohol solutions. The polycarbonate housing supports everyday aqueous filtration workflows while holding its form under elevated process pressure and maintains integrity through the filtration run. For routine sample preparation across many methods, the syringe filter folds clarification into one disposable step.

Technical Specifications

• Sterile-grade retention at sub-micron pore sizes
• Stable with aqueous solutions, buffers, and alcohols across pH 4 to 8
• Smooth surface with low extractables and a uniform pore structure
• Very low protein binding supports high recovery of dilute samples
• Absolute pore-size rating gives consistent retention across protocols

Housing Specifications

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

Filtering particulates upstream protects the column investment your methods depend on. Upstream buffer clarification keeps avoidable particulates out of your flow path while keeping the filtrate analytically clean.
