Whatman ReZist PTFE Syringe Filters, 1 µm, 30 mm, 500/Pk - 10463525

Whatman's established manufacturing platform delivers the consistency and lot-level documentation that analytical laboratories require. At the point of sample preparation, a syringe filter removes particulates before the sample reaches the instrument. Hydrophobic PTFE blocks aqueous ingress in vent and gas applications while staying chemically inert against solvents, acids, and alkalis and delivers absolute particle cutoff at the rated pore size. The polypropylene housing holds a reliable seal against the membrane edge while resisting aqueous acids, bases, and alcohols and maintains a low-dead-volume internal flow path. When sterile or particle-free preparation matters at the bench, the syringe filter delivers it with minimal added handling.

Technical Specifications

• Low extractables keep the chromatographic background clean
• Stable across a wide operating temperature range for demanding methods
• Absolute pore size rating gives consistent results across protocols
• Chemically inert against aggressive solvents, strong acids, and alkalis
• Filters aggressive organic solvents without swelling or breakdown

Housing Specifications

• Resists aqueous acids, bases, and alcohols in routine sample prep
• Medical-grade polypropylene with broad chemical compatibility
• Optimized internal geometry minimizes backpressure in service
• Thermal-bonded construction keeps adhesives out of the fluid path

Filtering aggressive solvents and reagents through a filter that holds up to the chemistry keeps your sample prep reliable. Reliable solvent prefiltration clears particulates from your organic samples ahead of HPLC and UPLC injection. Ask our friendly customer service team to confirm the pore size, membrane, and sterility options your filtration application calls for.

Hydrophobic

• 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
• 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
• Particulate Removal - Designed for removing high particulate loads, this filter aids in preventing premature clogging across diverse sample types
• Sample Clarification - Preventing premature clogging via rapid removal of high particulate loads to maintain high throughput in busy laboratories
