Pura Disc 25mm PTFE Syringe Filters, 0.1um, 50 Pk
Whatman SKU: 6784-2501

Whatman Puradisc PTFE Syringe Filters, 0.1 µm, 25 mm, 50/Pk - 6784-2501

Whatman manufactures under Cytiva's quality infrastructure, drawing on a filtration heritage that spans laboratory, environmental, and industrial applications. Sample preparation for chromatography often ends with a syringe filter on the path to the vial. Chemically inert PTFE resists attack from the harshest process chemistries and suits gas, vent, and solvent-stream filtration. The PP housing stays inert across common laboratory solvents and buffers while sustaining efficient flow on viscous samples 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

• Filters aggressive organic solvents without swelling or breakdown
• 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
• Sterilizing-grade gas and vent filtration at sub-micron pore sizes

Housing Specifications

• Reliable housing-to-membrane seal prevents bypass at rated pressure
• Resists aqueous acids, bases, and alcohols in routine sample prep
• Medical-grade polypropylene with broad chemical compatibility
• Low extractable contribution protects sensitive downstream analyses

Clarifying organic mobile phases before injection protects your chromatography while standing up to the solvent. 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
• 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
• Research & Development - Supports protocols that need to eliminate mycoplasma, providing the ability to prevent culture contamination
• Quality Control Testing - Optimized for Delivering reproducible results by eliminating mycoplasma in standard pharmaceutical protocols
