Pura Disc 25mm Nylon Syringe Filters, 1.0um, 50 Pk
Whatman SKU: 6750-2510

Whatman Puradisc Nylon Syringe Filters, 1 µm, 25 mm, 50/Pk - 6750-2510

Whatman's established manufacturing platform delivers the consistency and lot-level documentation that analytical laboratories require. Under hand pressure from the syringe, the membrane captures particulates as the sample passes through. Nylon wets on contact with aqueous samples through its hydrophilic surface while holding dimensional stability under rated backpressure and tolerates alcohols and aliphatic and aromatic solvents. The polypropylene housing routes flow to minimize backpressure in service while resisting aqueous acids, bases, and alcohols and maintains housing integrity through the filtration run. Where small-volume samples must reach the instrument clean, syringe filtration clears particulates in a single pass.

Technical Specifications

• Alkaline-resistant across a broad range of aqueous buffers
• Absolute pore size rating provides consistent results across filtration protocols
• Stable across the pH 3 to 12 operating range
• Low extractable contribution to sensitive analytical preparations
• Broad compatibility with alcohols, aliphatic, and aromatic solvents

Housing Specifications

• Resists aqueous acids, bases, and alcohols in routine sample prep
• Thermal-bonded construction keeps adhesives out of the fluid path
• Optimized internal geometry minimizes backpressure in service
• Reliable housing-to-membrane seal prevents bypass at rated pressure

Filtering every buffer before loading keeps your instrument running clean and uninterrupted. Upstream buffer clarification keeps avoidable particulates out of your flow path across routine and validated analytical methods.
