Pura Disc 13mm CA Syringe Filters, 0.45um, 100/Pk
Whatman SKU: 6771-1304

Whatman Puradisc Cellulose Acetate (CA) Syringe Filters, 0.45 µm, 13 mm, 100/Pk - 6771-1304

Whatman manufactures under Cytiva's quality infrastructure, drawing on a filtration heritage that spans laboratory, environmental, and industrial applications. A syringe filter holds its membrane in a leak-tight housing for clarification at the bench. The cellulose acetate membrane clarifies particulates at the rated pore size while handling water-based samples and low-alcohol solutions and holds a uniform pore structure for consistent results. The polypropylene housing routes flow to minimize backpressure in service and prevents sample bypass under rated operating pressure. When chromatographic methods demand particle-free injections, point-of-use syringe filtration clarifies the sample before it reaches the column.

Technical Specifications

• 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
• Smooth surface with low extractables and a uniform pore structure

Housing Specifications

• Medical-grade polypropylene with broad chemical compatibility
• Thermal-bonded construction keeps adhesives out of the fluid path
• Low extractable contribution protects sensitive downstream analyses
• Resists aqueous acids, bases, and alcohols in routine sample prep

Clarify your routine aqueous samples in a single pass and cut down on juggling multiple filter types at the bench. Consistent aqueous clarification keeps your sample preparation moving as a dependable step in your aqueous sample prep.
