Pura Disc 25mm Nylon Syringe Filters, 0.2um, 1000 Pk
Whatman SKU: 6753-2502

Whatman Puradisc Nylon Syringe Filters, 0.2 µm, 25 mm, 1000/Pk - 6753-2502

Whatman's brand recognition and documented performance history support specification in standardized analytical methods. Across analytical workflows, the syringe filter is where particulates leave the sample stream. Nylon provides sterile-grade retention at the rated sub-micron pore size and resists alkaline buffer systems. Polypropylene construction maintains housing integrity through the filtration run and maintains a low-dead-volume internal flow path. Where small-volume samples must reach the instrument clean, syringe filtration clears particulates in a single pass.

Technical Specifications

• Non-sterile for routine clarification and sample prep
• Low extractable contribution to sensitive analytical preparations
• High tensile strength for stability under elevated differential pressures
• Alkaline-resistant across a broad range of aqueous buffers
• Broad compatibility with alcohols, aliphatic, and aromatic solvents

Housing Specifications

• Low extractable contribution protects sensitive downstream analyses
• Resists aqueous acids, bases, and alcohols in routine sample prep
• Medical-grade polypropylene with broad chemical compatibility
• Optimized internal geometry minimizes backpressure in service

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.
