GD/X 25mm Syringe Filter, Nylon Filteration Medium, 0.2um (150 pcs)
Whatman SKU: 6871-2502

Whatman GD/X Nylon Syringe Filters, 0.2 µm, 25 mm, 150/Pk - 6871-2502

Whatman's brand recognition and documented performance history support specification in standardized analytical methods. 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 draws aqueous buffers through without pre-wetting. The polypropylene housing contributes minimal extractables to the filtrate and routes flow to minimize backpressure in service. When sterile or particle-free preparation matters at the bench, the syringe filter delivers it with minimal added handling.

Technical Specifications

• High tensile strength for stability under elevated differential pressures
• Alkaline-resistant across a broad range of aqueous buffers
• Layered prefiltration sustains flow through turbid, particulate-laden samples
• Broad compatibility with alcohols, aliphatic, and aromatic solvents
• Naturally hydrophilic surface wets without pre-wetting in aqueous applications

Housing Specifications

• Resists aqueous acids, bases, and alcohols in routine sample prep
• Medical-grade polypropylene with broad chemical compatibility
• Reliable housing-to-membrane seal prevents bypass at rated pressure
• Optimized internal geometry minimizes backpressure in service

Upstream clarification pays for itself by keeping your columns clear and your analytical day on schedule. Pre-injection filtration protects the resolution your methods depend on so your retention times and peak shapes stay consistent.
