ReZist Syringe Filter, 30mm, PTFE, 0.45um, 500/Pk
Whatman SKU: 10463515

Whatman ReZist PTFE Syringe Filters, 0.45 µm, 30 mm, 500/Pk - 10463515

Whatman's brand recognition and documented performance history support specification in standardized analytical methods. Syringe filters give the analyst a single-use device for clarifying samples right at the bench. Hydrophobic PTFE repels water while passing gases and solvents freely while withstanding aggressive organics that degrade other media and handles concentrated acids and bases. The PP housing stays inert across common laboratory solvents and buffers and maintains housing integrity through the filtration run. When sterile or particle-free preparation matters at the bench, the syringe filter delivers it with minimal added handling.

Technical Specifications

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

Housing Specifications

• Medical-grade polypropylene with broad chemical compatibility
• Reliable housing-to-membrane seal prevents bypass at rated pressure
• Optimized internal geometry minimizes backpressure in service
• Low extractable contribution protects sensitive downstream analyses

Clarifying organic mobile phases before injection protects your chromatography while standing up to the solvent. Solvent-stream filtration handles the solvents and reagents your methods rely on across the organic solvents and harsh reagents your methods use.

• Cryogenic Fluids - Remains functional and integral even at extreme temperatures, protecting sensitive equipment from damage
• Aerosol Sampling - The hydrophobic nature of PTFE allows for gas venting and air monitoring applications in harsh environments
• 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
• Research & Development - Supports protocols that need to remove particulates, providing the ability to protect analytical instruments
• Sample Clarification - Protecting analytical instruments via rapid removal of particulates to maintain high throughput in busy laboratories
