Pura Disc 13mm PTFE Syringe Filters, 0.2um, 2000 Pk
Whatman SKU: 6766-1302

Whatman Puradisc PTFE Syringe Filters, 0.2 µm, 13 mm, 2000/Pk - 6766-1302

Whatman applies the same process controls across its filtration portfolio, verifying rated performance at the production lot level. Syringe filters mount on a syringe to clarify a sample in a single manual pass. The PTFE matrix handles concentrated acids and bases across demanding methods while staying chemically inert against solvents, acids, and alkalis and delivers sterilizing-grade gas and vent filtration. The PP housing stays inert across common laboratory solvents and buffers while preventing sample bypass under rated operating pressure and sustains efficient flow on viscous samples. For routine sample preparation across many methods, the syringe filter folds clarification into one disposable step.

Technical Specifications

• Filters aggressive organic solvents without swelling or breakdown
• Stable across a wide operating temperature range for demanding methods
• Sterilizing-grade gas and vent filtration at sub-micron pore sizes
• Hydrophobic membrane repels water for gas, vent, and solvent filtration
• Absolute pore size rating gives consistent results across protocols

Housing Specifications

• Reliable housing-to-membrane seal prevents bypass at rated pressure
• Low extractable contribution protects sensitive downstream analyses
• Resists aqueous acids, bases, and alcohols in routine sample prep
• Thermal-bonded construction keeps adhesives out of the fluid path

Clarifying organic mobile phases before injection protects your chromatography while standing up to the solvent. Reliable solvent prefiltration clears particulates from your organic samples ahead of HPLC and UPLC injection.

• 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
• Biological Fluid Analysis - Protects sensitive downstream instruments from filtering contaminants that can cause system failure
• Research & Development - Supports protocols that need to filter contaminants, providing the ability to optimize sample clarity
