Pura Disc 13mm PTFE Syringe Filters, 0.1um, 100/Pk
Whatman SKU: 6784-1301

Whatman Puradisc PTFE Syringe Filters, 0.1 µm, 13 mm, 100/Pk - 6784-1301

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 hydrophobic PTFE membrane provides bacterial retention in gas and vent streams and stays chemically inert against solvents, acids, and alkalis. Polypropylene construction maintains housing integrity through the filtration run while maintaining a low-dead-volume internal flow path and resists aqueous acids, bases, and alcohols. Where small-volume samples must reach the instrument clean, syringe filtration clears particulates in a single pass.

Technical Specifications

• Filters aggressive organic solvents without swelling or breakdown
• Chemically inert against aggressive solvents, strong acids, and alkalis
• Absolute pore size rating gives consistent results across protocols
• Sterilizing-grade gas and vent filtration at sub-micron pore sizes
• Stable across a wide operating temperature range for demanding methods

Housing Specifications

• 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
• Medical-grade polypropylene with broad chemical compatibility

Clarifying organic mobile phases before injection protects your chromatography while standing up to the solvent. Reliable solvent prefiltration clears particulates from your organic samples from reaction mixtures and crude extracts through final analysis. Review our Chemical Compatibility Chart, or ask technical service to confirm chemical compatibility for your specific application.

• 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
• Cryogenic Fluids - Remains functional and integral even at extreme temperatures, protecting sensitive equipment from damage
• Quality Control Testing - Optimized for delivering reproducible results by eliminating mycoplasma in standard pharmaceutical protocols
• Research & Development - Supports protocols that need to eliminate mycoplasma, providing the ability to prevent culture contamination
