Pura Disc 25mm PES Syringe Filters, 1.0um, 50 Pk
Whatman SKU: 6780-2510

Whatman Puradisc Polyethersulfone (PES) Syringe Filters, 1 µm, 25 mm, 50/Pk - 6780-2510

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. The PES membrane keeps protein adsorption low for accurate sample recovery while accepting water-based reagents without preconditioning and stays stable across the pH 1 to 14 range. The PP housing sustains efficient flow on viscous samples while contributing minimal extractables to the filtrate and stays inert across common laboratory solvents. Where small-volume samples must reach the instrument clean, syringe filtration clears particulates in a single pass.

Technical Specifications

• Absolute pore size rating gives consistent results across protocols
• Broad compatibility with aqueous buffers, aliphatic alcohols, glycols, and strong bases
• Low protein binding preserves dilute analytes for maximum recovery
• High flow rate with low extractable background for clean preparations
• Naturally hydrophilic surface wets without pre-wetting in aqueous applications

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 every buffer before loading keeps your instrument running clean and uninterrupted. Upstream buffer clarification keeps avoidable particulates out of your flow path before they reach the column inlet or detector.
