GD/X 13mm Syringe Filter, PTFE Filteration Medium, 0.2um (150 pcs)
Whatman SKU: 6875-1302

Whatman GD/X PTFE Syringe Filters, 0.2 µm, 13 mm, 150/Pk - 6875-1302

Whatman's expertise in cellulose, glass fiber, and polymeric membrane production guides material selection and quality control. Sample preparation for chromatography often ends with a syringe filter on the path to the vial. Chemically inert PTFE resists attack from the harshest process chemistries while filtering aggressive organic solvents without breakdown and blocks aqueous ingress in vent applications. The polypropylene housing resists aqueous acids, bases, and alcohols while holding extractables low for sensitive analyses and maintains a low-dead-volume internal flow path. 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
• Sterilizing-grade gas and vent filtration at sub-micron pore sizes
• Filters aggressive organic solvents without swelling or breakdown
• Stable across a wide operating temperature range for demanding methods
• Low extractables keep the chromatographic background clean

Housing Specifications

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

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 so your downstream method starts with a clean sample. Ask our friendly customer service team to confirm the pore size, membrane, and sterility options your filtration application calls for.

• Organic Mobile Phases - Ideal for filtering 100% organic solvents in HPLC and GC workflows without any membrane degradation
• Aerosol Sampling - The hydrophobic nature of PTFE allows for gas venting and air monitoring applications in harsh environments
• 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
• Environmental Monitoring - Ideal for filtering contaminants in water and wastewater analysis to ensure regulatory compliance
• Sample Clarification - Optimizing sample clarity via rapid filtering of contaminants to maintain high throughput in busy laboratories
