Pura Disc 25mm Nylon Syringe Filters, 0.2um, 50 Pk
Whatman SKU: 6750-2502

Whatman Puradisc Nylon Syringe Filters, 0.2 µm, 25 mm, 50/Pk - 6750-2502

Whatman's expertise in cellulose, glass fiber, and polymeric membrane production guides material selection and quality control. Syringe filters mount on a syringe to clarify a sample in a single manual pass. Nylon wets on contact with aqueous samples through its hydrophilic surface while providing sterile-grade retention at sub-micron pore sizes and resists alkaline buffer systems. The polypropylene housing routes flow to minimize backpressure in service while holding a reliable seal against the membrane edge and stays inert across common laboratory solvents. For routine sample preparation across many methods, the syringe filter folds clarification into one disposable step.

Technical Specifications

• Broad compatibility with alcohols, aliphatic, and aromatic solvents
• Low extractable contribution to sensitive analytical preparations
• Alkaline-resistant across a broad range of aqueous buffers
• Non-sterile for routine clarification and sample prep
• Absolute pore size rating provides consistent results across filtration protocols

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

Clarify your routine aqueous samples in a single pass and cut down on juggling multiple filter types at the bench. General-purpose aqueous filtration supports the sample types you handle every day from reagent and buffer preparation through routine sample clarification.
