Whatman SKU: 6875-1304

Whatman GD/X PTFE Syringe Filters, 0.45 µm, 13 mm, 150/Pk - 6875-1304

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 seats a membrane in a sealed housing that threads onto a standard luer fitting. PTFE filters aggressive organic solvents without swelling or breakdown and resists attack from the harshest process chemistries. The polypropylene housing routes flow to minimize backpressure in service while resisting aqueous acids, bases, and alcohols and prevents sample bypass under rated operating pressure. Where small-volume samples must reach the instrument clean, syringe filtration clears particulates in a single pass.

Technical Specifications

• Chemically inert against aggressive solvents, strong acids, and alkalis
• Absolute pore size rating gives consistent results across protocols
• Stable across a wide operating temperature range for demanding methods
• Low extractables keep the chromatographic background clean
• Hydrophobic membrane repels water for gas, vent, and solvent filtration

Housing Specifications

• Reliable housing-to-membrane seal prevents bypass at rated pressure
• Optimized internal geometry minimizes backpressure in service
• Thermal-bonded construction keeps adhesives out of the fluid path
• Resists aqueous acids, bases, and alcohols in routine sample prep

Filtering aggressive solvents and reagents through a filter that holds up to the chemistry keeps your sample prep reliable. Reliable solvent prefiltration clears particulates from your organic samples from reaction mixtures and crude extracts through final analysis.

• Organic Mobile Phases - Ideal for filtering 100% organic solvents in HPLC and GC workflows without any membrane degradation
• 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
• Cryogenic Fluids - Remains functional and integral even at extreme temperatures, protecting sensitive equipment from damage
• General Laboratory Filtration - Increases workflow efficiency by protecting analytical instruments without sacrificing flow rates
• Analytical Sample Prep - Optimized to ensure data integrity by effectively removing particulates before instrumental analysis
