Pura Disc Aqua 30mm Syringe Filter, 0.45um, Sterile, 500 Pk
Whatman SKU: 10462650

Whatman Puradisc Cellulose Acetate (CA) Syringe Filters, 0.45 µm, 30 mm, 500/Pk - 10462650

Whatman's expertise in cellulose, glass fiber, and polymeric membrane production guides material selection and quality control. Syringe filters give the analyst a single-use device for clarifying samples right at the bench. Naturally hydrophilic cellulose acetate wets easily with aqueous samples and holds a sharp particle cutoff at the rated pore size. High-strength polycarbonate construction resists damage during demanding use and holds a reliable seal against the membrane edge. Where small-volume samples must reach the instrument clean, syringe filtration clears particulates in a single pass.

Technical Specifications

• Very low protein binding supports high recovery of dilute samples
• Smooth surface with low extractables and a uniform pore structure
• Naturally hydrophilic surface wets readily with aqueous samples
• Stable with aqueous solutions, buffers, and alcohols across pH 4 to 8
• Absolute pore-size rating gives consistent retention across protocols

Housing Specifications

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

Reproducible separations start with samples that reach the column free of particulates. Upstream sample clarification keeps your separations clean and reproducible so your filtrate reaches the column clean. Ask our friendly customer service team to confirm the pore size, membrane, and sterility options your filtration application calls for.
