GD/X 13mm Syringe Filter, PTFE Filteration Medium, 0.45um (150 pcs)
Whatman SKU: 6874-1304

Whatman GD/X PTFE Syringe Filters, 0.45 µm, 13 mm, 150/Pk - 6874-1304

Whatman's brand recognition and documented performance history support specification in standardized analytical methods. A syringe filter seats a membrane in a sealed housing that threads onto a standard luer fitting. Hydrophobic PTFE repels water while passing gases and solvents freely and filters aggressive organic solvents without breakdown. Polypropylene construction resists chemical degradation from routine sample matrices while contributing minimal extractables to the filtrate and maintains housing integrity through the filtration run. For routine sample preparation across many methods, the syringe filter folds clarification into one disposable step.

Technical Specifications

• Absolute pore size rating gives consistent results across protocols
• Low extractables keep the chromatographic background clean
• Filters aggressive organic solvents without swelling or breakdown
• Chemically inert against aggressive solvents, strong acids, and alkalis
• Hydrophobic membrane repels water for gas, vent, and solvent filtration

Housing Specifications

• Optimized internal geometry minimizes backpressure in service
• Thermal-bonded construction keeps adhesives out of the fluid path
• Reliable housing-to-membrane seal prevents bypass at rated pressure
• Medical-grade polypropylene with broad chemical compatibility

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 so your downstream method starts with a clean sample.

Hydrophobic

• Aggressive Solvent Filtration - PTFE is chemically inert, making it the only choice for filtering strong acids and bases
• Cryogenic Fluids - Remains functional and integral even at extreme temperatures, protecting sensitive equipment from damage
• 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
• Sample Clarification - Protecting analytical instruments via rapid removal of particulates to maintain high throughput in busy laboratories
• Biological Fluid Analysis - Protects sensitive downstream instruments from removing particulates that can cause system failure
