Pura Disc 25mm Nylon Syringe Filters, 0.2um, 200 Pk
Whatman SKU: 6751-2502

Whatman Puradisc Nylon Syringe Filters, 0.2 µm, 25 mm, 200/Pk - 6751-2502

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. Nylon provides sterile-grade retention at the rated sub-micron pore size while resisting particle shedding across the run and accepts water-based samples without surfactant conditioning. Polypropylene construction resists chemical degradation from routine sample matrices and holds extractables low for sensitive analyses. 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
• High tensile strength for stability under elevated differential pressures
• Low extractable contribution to sensitive analytical preparations
• 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
• Reliable housing-to-membrane seal prevents bypass at rated pressure
• Medical-grade polypropylene with broad chemical compatibility
• Low extractable contribution protects sensitive downstream analyses

Removing particulates from your buffers and mobile phases extends column life and keeps your baselines steady. Reliable particulate removal protects your instruments and your data so column life and baseline stability stay predictable.
