Whatman ReZist PTFE Syringe Filters, 0.45 µm, 13 mm, 100/Pk - 10463713

Whatman's expertise in cellulose, glass fiber, and polymeric membrane production guides material selection and quality control. A syringe filter seats a membrane in a sealed housing that threads onto a standard luer fitting. PTFE filters aggressive organic solvents without swelling or breakdown and repels water while passing gases and solvents freely. The polypropylene housing routes flow to minimize backpressure in service and resists degradation from routine sample matrices. When sterile or particle-free preparation matters at the bench, the syringe filter delivers it with minimal added handling.

Technical Specifications

• Filters aggressive organic solvents without swelling or breakdown
• Hydrophobic membrane repels water for gas, vent, and solvent filtration
• Low extractables keep the chromatographic background clean
• Chemically inert against aggressive solvents, strong acids, and alkalis
• Absolute pore size rating gives consistent results across protocols

Housing Specifications

• Resists aqueous acids, bases, and alcohols in routine sample prep
• Reliable housing-to-membrane seal prevents bypass at rated pressure
• Optimized internal geometry minimizes backpressure in service
• 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
• 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
• Environmental Monitoring - Ideal for removing particulates in water and wastewater analysis to ensure regulatory compliance
• Particulate Removal - Designed for removing particulates, this filter aids in protecting analytical instruments across diverse sample types
