Pura Disc 13mm PTFE Syringe Filters, 1.0um, 100/Pk
Whatman SKU: 6784-1310

Whatman Puradisc PTFE Syringe Filters, 1 µm, 13 mm, 100/Pk - 6784-1310

Whatman's brand recognition and documented performance history support specification in standardized analytical methods. At the point of sample preparation, a syringe filter removes particulates before the sample reaches the instrument. PTFE stays chemically inert against aggressive solvents, strong acids, and alkalis while holding consistent absolute retention at the rated pore size and filters aggressive organic solvents without breakdown. The polypropylene housing resists aqueous acids, bases, and alcohols while preventing sample bypass under rated operating pressure and contributes minimal extractables to the filtrate. When method reproducibility rests on consistent sample prep, syringe filtration holds that standard injection after injection.

Technical Specifications

• Low extractables keep the chromatographic background clean
• Absolute pore size rating gives consistent results across protocols
• Hydrophobic membrane repels water for gas, vent, and solvent filtration
• Chemically inert against aggressive solvents, strong acids, and alkalis
• Stable across a wide operating temperature range for demanding methods

Housing Specifications

• Medical-grade polypropylene with broad chemical compatibility
• Optimized internal geometry minimizes backpressure in service
• Thermal-bonded construction keeps adhesives out of the fluid path
• Resists aqueous acids, bases, and alcohols in routine sample prep

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 across the organic solvents and harsh reagents your methods use.

• 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
• Cryogenic Fluids - Remains functional and integral even at extreme temperatures, protecting sensitive equipment from damage
• Sample Clarification - Preventing premature clogging via rapid removal of high particulate loads to maintain high throughput in busy laboratories
• General Laboratory Filtration - Increases workflow efficiency by preventing premature clogging without sacrificing flow rates
