Whatman Puradisc Nylon Syringe Filters, 0.1 µm, 13 mm, 100/Pk - 6789-1301

Whatman's established manufacturing platform delivers the consistency and lot-level documentation that analytical laboratories require. Syringe filters give the analyst a single-use device for clarifying samples right at the bench. Nylon stays stable across the pH 3 to 12 buffer range while providing sterile-grade retention at sub-micron pore sizes and ships in economical bulk non-sterile packaging. The polypropylene housing contributes minimal extractables to the filtrate while holding a reliable seal against the membrane edge and maintains a low-dead-volume internal flow path. Where analytical results depend on clean samples, syringe filtration removes particulates at the moment of preparation.

Technical Specifications

• Stable across the pH 3 to 12 operating range
• Naturally hydrophilic surface wets without pre-wetting in aqueous applications
• Alkaline-resistant across a broad range of aqueous buffers
• Low extractable contribution to sensitive analytical preparations
• High tensile strength for stability under elevated differential pressures

Housing Specifications

• Low extractable contribution protects sensitive downstream analyses
• Reliable housing-to-membrane seal prevents bypass at rated pressure
• Resists aqueous acids, bases, and alcohols in routine sample prep
• Thermal-bonded construction keeps adhesives out of the fluid path

Filtering buffers, reagents, and aqueous samples keeps your preparation moving and consistent. General-purpose aqueous filtration supports the sample types you handle every day across your water-analysis and general analytical workflows.
