GD/X 25mm Syringe Filter, Nylon Filteration Medium, 5.0um (150 pcs)
Whatman SKU: 6870-2550

Whatman GD/X Nylon Syringe Filters, 5 µm, 25 mm, 150/Pk - 6870-2550

Whatman applies over a century of filtration media expertise, manufacturing under the quality standards that established its products as global laboratory references. A syringe filter holds its membrane in a leak-tight housing for clarification at the bench. The nylon membrane comes in a non-sterile format for routine analytical preparation while staying stable across the pH 3 to 12 buffer range and holds dimensional stability under rated backpressure. The PP housing prevents sample bypass under rated operating pressure and sustains efficient flow on viscous samples. For routine sample preparation across many methods, the syringe filter folds clarification into one disposable step.

Technical Specifications

• Low extractable contribution to sensitive analytical preparations
• Non-sterile for routine clarification and sample prep
• Layered prefiltration sustains flow through turbid, particulate-laden samples
• Absolute pore size rating provides consistent results across filtration protocols
• High tensile strength for stability under elevated differential pressures

Housing Specifications

• Resists aqueous acids, bases, and alcohols in routine sample prep
• Medical-grade polypropylene with broad chemical compatibility
• Optimized internal geometry minimizes backpressure in service
• Thermal-bonded construction keeps adhesives out of the fluid path

Removing particulates from your buffers and mobile phases extends column life and keeps your baselines steady. Upstream buffer clarification keeps avoidable particulates out of your flow path while keeping the filtrate analytically clean.
