Pura Disc 13mm H-PTFE Syringe Filters 0.2um, Hydrophilic, 2000 Pk
Whatman SKU: 6774-1302

Whatman Puradisc Water-Wettable PTFE Syringe Filters, 0.2 µm, 13 mm, 2000/Pk - 6774-1302

Whatman applies the same process controls across its filtration portfolio, verifying rated performance at the production lot level. At the point of sample preparation, a syringe filter removes particulates before the sample reaches the instrument. Water-wettable PTFE stays chemically inert against aggressive solvents and acids in service while accepting aqueous samples without pre-wetting and provides sterile-grade filtration at sub-micron pore sizes. Polypropylene construction maintains housing integrity through the filtration run and resists aqueous acids, bases, and alcohols. For routine sample preparation across many methods, the syringe filter folds clarification into one disposable step.

Technical Specifications

• Low protein binding preserves dilute analytes for maximum recovery
• Sterile-grade retention at sub-micron pore sizes
• Absolute pore-size rating gives consistent retention across protocols
• Chemically inert to aggressive organic solvents, strong acids, and alkalis
• Universal compatibility across aqueous buffers and organic solvents

Housing Specifications

• Reliable housing-to-membrane seal prevents bypass at rated pressure
• Medical-grade polypropylene with broad chemical compatibility
• Optimized internal geometry minimizes backpressure in service
• Resists aqueous acids, bases, and alcohols in routine sample prep

Clarify your routine aqueous samples in a single pass and cut down on juggling multiple filter types at the bench. Consistent aqueous clarification keeps your sample preparation moving from the first sample of the day through the last.

Hydrophobic

• Cryogenic Fluids - Remains functional and integral even at extreme temperatures, protecting sensitive equipment from damage
• 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
• Research & Development - Supports protocols that need to filter contaminants, providing the ability to optimize sample clarity
• Particulate Removal - Designed for filtering contaminants, this filter aids in optimizing sample clarity across diverse sample types
