Whatman ReZist PTFE Syringe Filters, 5 µm, 30 mm, 100/Pk - 10463533

Whatman applies over a century of filtration media expertise, manufacturing under the quality standards that established its products as global laboratory references. Syringe filters mount on a syringe to clarify a sample in a single manual pass. The PTFE membrane withstands aggressive organics that degrade other media while blocking aqueous ingress in vent applications and handles concentrated acids and bases. The polypropylene housing routes flow to minimize backpressure in service while staying inert across common laboratory solvents and contributes minimal extractables to the filtrate. 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
• Chemically inert against aggressive solvents, strong acids, and alkalis
• Low extractables keep the chromatographic background clean
• Stable across a wide operating temperature range for demanding methods

Housing Specifications

• Low extractable contribution protects sensitive downstream analyses
• Thermal-bonded construction keeps adhesives out of the fluid path
• Medical-grade polypropylene with broad chemical compatibility
• Reliable housing-to-membrane seal prevents bypass at rated pressure

Filtering aggressive solvents and reagents through a filter that holds up to the chemistry keeps your sample prep reliable. Solvent-stream filtration handles the solvents and reagents your methods rely on from organic mobile-phase prep through reagent clarification.

• 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
• Aerosol Sampling - The hydrophobic nature of PTFE allows for gas venting and air monitoring applications in harsh environments
• General Laboratory Filtration - Increases workflow efficiency by protecting upstream systems without sacrificing flow rates
• Biological Fluid Analysis - Protects sensitive downstream instruments from clearing gross precipitates that can cause system failure
