Pura Disc 13mm H-PTFE Syringe Filters 0.2um, Hydrophilic, 500 Pk SKU: 6773-1302

Hydrophilic Polytetrafluoroethylene (PTFE) Syringe Filters, 0.2µm, 13mm - 6773-1302

Ensuring the biological integrity of sensitive media begins with reliable filtration, and the Hydrophilic Polytetrafluoroethylene (PTFE) Whatman Puradisc™ Syringe Filter, 13mm, 0.2µm, 500/pk is engineered to deliver sterile effluents with every use. Driving this efficiency is the integration of a hydrophobic Hydrophilic Polytetrafluoroethylene (PTFE) membrane, ensuring high recovery of sensitive samples while maintaining a sterile effluent. Complementing the membrane's purity, the housing's thermal bonding eliminates the need for adhesives, removing a common source of extractable contamination. Meeting the needs of regulated environments, this series supports compliance with stringent purity protocols across pharmaceutical and environmental applications.

Key Hydrophilic Polytetrafluoroethylene (PTFE) Membrane Characteristics

• Hydrophilic Polytetrafluoroethylene (PTFE) membrane treated for hydrophilic affinity
• Low Protein Binding characteristics
• Extreme chemical resistance to aggressive solvents, acids, and bases
• Hydrophobic version acts as an effective moisture barrier
• Verified 0.2 retention rating for clarification

Key Housing Characteristics

• High-purity Polypropylene encapsulation housing
• Luer-Lok/ Luer Slip for secure fitting
• 1.3cm² effective filtration area

Hydrophobic

• 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
• 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
• Analytical Sample Prep - Optimized to ensure data integrity by effectively filtering contaminants before instrumental analysis
• Sample Clarification - Optimizing sample clarity via rapid filtering of contaminants to maintain high throughput in busy laboratories
