Pura Disc FP 30mm CA Syringe Filter, 1.2um, Sterile, 50 Pk
Whatman SKU: 10462260

Whatman Puradisc Cellulose Acetate (CA) Syringe Filters, 1.2 µm, 30 mm, 50/Pk - 10462260

Whatman's brand recognition and documented performance history support specification in standardized analytical methods. A syringe filter holds its membrane in a leak-tight housing for clarification at the bench. Cellulose acetate holds a uniform pore structure for consistent results and clarifies particulates at the rated pore size. The polycarbonate housing holds its form under elevated process pressure while preventing sample bypass under rated operating pressure and stands up to rugged field and bench handling. When chromatographic methods demand particle-free injections, point-of-use syringe filtration clarifies the sample before it reaches the column.

Technical Specifications

• 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
• Naturally hydrophilic surface wets readily with aqueous samples
• Absolute pore-size rating gives consistent retention across protocols

Housing Specifications

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

Filtering every buffer before loading keeps your instrument running clean and uninterrupted. Upstream buffer clarification keeps avoidable particulates out of your flow path before they reach the column inlet or detector.
