Whatman ReZist PTFE Syringe Filters, 5 µm, 30 mm, 500/Pk - 10463535

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. The hydrophobic PTFE membrane suits gas, vent, and solvent-stream filtration while handling concentrated acids and bases and clarifies solvent streams at the rated pore size. Polypropylene construction maintains a low-dead-volume internal flow path while resisting degradation from routine sample matrices and holds a reliable seal against the membrane edge. Where small-volume samples must reach the instrument clean, syringe filtration clears particulates in a single pass.

Technical Specifications

• Hydrophobic membrane repels water for gas, vent, and solvent filtration
• Stable across a wide operating temperature range for demanding methods
• Chemically inert against aggressive solvents, strong acids, and alkalis
• Low extractables keep the chromatographic background clean
• Filters aggressive organic solvents without swelling or breakdown

Housing Specifications

• Thermal-bonded construction keeps adhesives out of the fluid path
• Low extractable contribution protects sensitive downstream analyses
• Optimized internal geometry minimizes backpressure in service
• Reliable housing-to-membrane seal prevents bypass at rated pressure

Handling the harsh solvents your methods demand calls for a filter that holds up to the chemistry, pass after pass. Solvent-stream filtration handles the solvents and reagents your methods rely on from organic mobile-phase prep through reagent clarification.

• 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
• 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
• Analytical Sample Prep - Ensures data integrity by effectively clearing gross precipitates before instrumental analysis
• Particulate Removal - Designed for clearing gross precipitates, this filter aids in protecting upstream systems across diverse sample types
