Pura Disc 13mm H-PTFE Syringe Filters 0.45um, Hydrophilic, 2000 Pk SKU: 6774-1304

Hydrophilic Polytetrafluoroethylene (PTFE) Syringe Filters, 0.45µm, 13mm - 6774-1304

Streamline your sample preparation workflows with the Hydrophilic Polytetrafluoroethylene (PTFE) Whatman Puradisc™ Syringe Filter, 13mm, 0.45µm, 2000/pk, constructed to handle high particulate loads while maintaining rapid throughput. To ensure analytical precision, the unit is constructed with a high-grade Hydrophilic Polytetrafluoroethylene (PTFE) membrane providing a consistent 0.45 cutoff that passes only your target analyte. Complementing the membrane's purity, the housing's thermal bonding eliminates the need for adhesives, removing a common source of extractable contamination. The result is a filtration solution manufactured in an ISO-certified facility that minimizes distinct interference, providing clean baselines for publication-quality data.

Key Hydrophilic Polytetrafluoroethylene (PTFE) Membrane Characteristics

• 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
• 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
• Particulate Removal - Designed for removing particulates, this filter aids in protecting analytical instruments across diverse sample types
• General Laboratory Filtration - Increases workflow efficiency by protecting analytical instruments without sacrificing flow rates
