Whatman
Pura Disc 25mm PTFE Syringe Filters, 1.0um, 50 Pk SKU: 6784-2510

Polytetrafluoroethylene (PTFE) Syringe Filters, 1.0µm, 25mm - 6784-2510

Reducing background noise in analytical assays begins with proper clarification, and the Polytetrafluoroethylene (PTFE) Whatman Puradisc, 25mm, Syringe Filter, 1.0µm, nonsterile 50/pk is engineered to remove interfering solids efficiently. To ensure analytical precision, the unit is constructed with a high-grade Polytetrafluoroethylene (PTFE) membrane providing a consistent 1.0 cutoff that passes only your target analyte. To guarantee structural reliability, each unit undergoes strict quality control to ensure the housing and membrane seal withstand standard operating pressures without leakage. Meeting the needs of regulated environments, this series supports compliance with stringent purity protocols across pharmaceutical and environmental applications.

Key Polytetrafluoroethylene (PTFE) Membrane Characteristics

• Polytetrafluoroethylene (PTFE) membrane with hydrophobic (requires pre-wetting) or hydrophilic (if treated) affinity
• Low Protein Binding characteristics
• Extreme chemical resistance to aggressive solvents, acids, and bases
• Hydrophobic version acts as an effective moisture barrier
• Verified 1.0 retention rating for clarification

Key Housing Characteristics

• High-purity Polypropylene encapsulation housing
• Luer-Lok/ Luer Slip for secure fitting
• 4.2cm² effective filtration area
• <100µl holdup volume to minimize sample loss

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
• 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
• Biological Fluid Analysis - Protects sensitive downstream instruments from removing high particulate loads that can cause system failure
• Environmental Monitoring - Ideal for removing high particulate loads in water and wastewater analysis to ensure regulatory compliance
