Pura Disc 13mm PTFE Syringe Filters, 0.2um, 100/Pk
Whatman SKU: 6784-1302

Whatman Puradisc PTFE Syringe Filters, 0.2 µm, 13 mm, 100/Pk - 6784-1302

Whatman applies the same process controls across its filtration portfolio, verifying rated performance at the production lot level. Under hand pressure from the syringe, the membrane captures particulates as the sample passes through. Chemically inert PTFE resists attack from the harshest process chemistries while suiting gas, vent, and solvent-stream filtration and provides bacterial retention in gas and vent streams. Polypropylene construction holds extractable contribution low for sensitive analyses and sustains efficient flow on viscous samples. Where small-volume samples must reach the instrument clean, syringe filtration clears particulates in a single pass.

Technical Specifications

• Hydrophobic membrane repels water for gas, vent, and solvent filtration
• Absolute pore size rating gives consistent results across protocols
• Chemically inert against aggressive solvents, strong acids, and alkalis
• Filters aggressive organic solvents without swelling or breakdown
• Sterilizing-grade gas and vent filtration at sub-micron pore sizes

Housing Specifications

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

Handling the harsh solvents your methods demand calls for a filter that holds up to the chemistry, pass after pass. Solvent-stream filtration handles the solvents and reagents your methods rely on from organic mobile-phase prep through reagent clarification. Call on the Tisch Scientific team to standardize filtration products across your methods with volume pricing and documentation.

• 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
• Organic Mobile Phases - Ideal for filtering 100% organic solvents in HPLC and GC workflows without any membrane degradation
• Cryogenic Fluids - Remains functional and integral even at extreme temperatures, protecting sensitive equipment from damage
• Analytical Sample Prep - Optimized to ensure data integrity by effectively filtering contaminants before instrumental analysis
• Environmental Monitoring - Ideal for filtering contaminants in water and wastewater analysis to ensure regulatory compliance
