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

Whatman Puradisc Water-Wettable PTFE Syringe Filters, 0.2 µm, 13 mm, 500/Pk - 6773-1302

Whatman's established manufacturing platform delivers the consistency and lot-level documentation that analytical laboratories require. A syringe filter holds its membrane in a leak-tight housing for clarification at the bench. The hydrophilic PTFE membrane resists strong acids, alkalis, and organic solvents and accepts aqueous samples without pre-wetting. The polypropylene housing routes flow to minimize backpressure in service while resisting aqueous acids, bases, and alcohols in routine use and prevents sample bypass under rated operating pressure. For routine sample preparation across many methods, the syringe filter folds clarification into one disposable step.

Technical Specifications

• Chemically inert to aggressive organic solvents, strong acids, and alkalis
• Universal compatibility across aqueous buffers and organic solvents
• Absolute pore-size rating gives consistent retention across protocols
• Low protein binding preserves dilute analytes for maximum recovery
• Water-wettable surface wets directly with both aqueous and organic samples

Housing Specifications

• Resists stress cracking from aqueous salt and buffer solutions
• Thermal-bonded construction keeps adhesives out of the fluid path
• Plasticizer-free polyolefin construction keeps the fluid path clean
• Resists aqueous acids, bases, and alcohols in routine sample prep

Upstream clarification pays for itself by keeping your columns clear and your analytical day on schedule. Pre-injection filtration protects the resolution your methods depend on across your chromatography methods.

Wettability

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
