GD/X 25mm Syringe Filter, PTFE Filteration Medium, 0.2um (150 pcs)
Whatman SKU: 6874-2502

Whatman GD/X PTFE Syringe Filters, 0.2 µm, 25 mm, 150/Pk - 6874-2502

Whatman applies over a century of filtration media expertise, manufacturing under the quality standards that established its products as global laboratory references. Under hand pressure from the syringe, the membrane captures particulates as the sample passes through. PTFE filters aggressive organic solvents without swelling or breakdown while blocking aqueous ingress in vent applications and achieves sterile-grade retention in gas and vent service. Polypropylene construction maintains a low-dead-volume internal flow path while resisting aqueous acids, bases, and alcohols and prevents sample bypass under rated operating pressure. When method reproducibility rests on consistent sample prep, syringe filtration holds that standard injection after injection.

Technical Specifications

• Low extractables keep the chromatographic background clean
• Filters aggressive organic solvents without swelling or breakdown
• Absolute pore size rating gives consistent results across protocols
• Chemically inert against aggressive solvents, strong acids, and alkalis
• Sterilizing-grade gas and vent filtration at sub-micron pore sizes

Housing Specifications

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

Handling the harsh solvents your methods demand calls for a filter that holds up to the chemistry, pass after pass. Reliable solvent prefiltration clears particulates from your organic samples ahead of HPLC and UPLC injection. Review our Chemical Compatibility Chart, or ask technical service to confirm chemical compatibility for your specific application.

Hydrophobic

• Cryogenic Fluids - Remains functional and integral even at extreme temperatures, protecting sensitive equipment from damage
• Aggressive Solvent Filtration - PTFE is chemically inert, making it the only choice for filtering strong acids and bases
• Aerosol Sampling - The hydrophobic nature of PTFE allows for gas venting and air monitoring applications in harsh environments
• Organic Mobile Phases - Ideal for filtering 100% organic solvents in HPLC and GC workflows without any membrane degradation
• Quality Control Testing - Optimized for delivering reproducible results by filtering contaminants in standard pharmaceutical protocols
• Biological Fluid Analysis - Protects sensitive downstream instruments from filtering contaminants that can cause system failure
