Whatman Puradisc PTFE Syringe Filters, 5 µm, 13 mm, 100/Pk - 6784-1350

Whatman applies the same process controls across its filtration portfolio, verifying rated performance at the production lot level. A syringe filter seats a membrane in a sealed housing that threads onto a standard luer fitting. Hydrophobic PTFE repels water while passing gases and solvents freely while handling concentrated acids and bases and withstands aggressive organics that degrade other media. The polypropylene housing routes flow to minimize backpressure in service while holding a reliable seal against the membrane edge and resists aqueous acids, bases, and alcohols. When sterile or particle-free preparation matters at the bench, the syringe filter delivers it with minimal added handling.

Technical Specifications

• Chemically inert against aggressive solvents, strong acids, and alkalis
• Stable across a wide operating temperature range for demanding methods
• Hydrophobic membrane repels water for gas, vent, and solvent filtration
• Low extractables keep the chromatographic background clean
• Filters aggressive organic solvents without swelling or breakdown

Housing Specifications

• Medical-grade polypropylene with broad chemical compatibility
• Thermal-bonded construction keeps adhesives out of the fluid path
• Reliable housing-to-membrane seal prevents bypass at rated pressure
• 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 from organic mobile-phase prep through reagent clarification.

Hydrophobic

• 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
• 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
• Research & Development - Supports protocols that need to clear gross precipitates, providing the ability to protect upstream systems
• Analytical Sample Prep - Ensures data integrity by effectively clearing gross precipitates before instrumental analysis
