Pura Disc 13mm PVDF Syringe Filters, 0.45um, 500 Pk
Whatman SKU: 6792-1304

Whatman Puradisc PVDF Syringe Filters, 0.45 µm, 13 mm, 500/Pk - 6792-1304

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. Hydrophilic PVDF suits HPLC sample preparation and aqueous clarification while preserving dilute proteins and analytes in the filtrate and holds up to alcohols and mild hydrocarbon solvents. Polypropylene construction resists chemical degradation from routine sample matrices and holds extractables low for sensitive analyses. Where analytical results depend on clean samples, syringe filtration removes particulates at the moment of preparation.

Technical Specifications

• Low extractables preserve a clean chromatographic baseline
• Hydrophilic surface wets aqueous and HPLC samples without pre-wetting
• Mechanically durable membrane holds integrity under filtration pressure
• Absolute pore size rating gives consistent results across protocols
• Resists HPLC mobile phases, alcohols, and mild hydrocarbons

Housing Specifications

• Reliable housing-to-membrane seal prevents bypass at rated pressure
• Low extractable contribution protects sensitive downstream analyses
• Resists aqueous acids, bases, and alcohols in routine sample prep
• Optimized internal geometry minimizes backpressure in service

Upstream clarification pays for itself by keeping your columns clear and your analytical day on schedule. Upstream sample clarification keeps your separations clean and reproducible so your filtrate reaches the column clean.
