Whatman SKU: 10463513

Whatman ReZist PTFE Syringe Filters, 0.45 µm, 30 mm, 100/Pk - 10463513

Whatman manufactures under Cytiva's quality infrastructure, drawing on a filtration heritage that spans laboratory, environmental, and industrial applications. Syringe filters give the analyst a single-use device for clarifying samples right at the bench. The PTFE matrix handles concentrated acids and bases across demanding methods while repelling water and passing gases and solvents freely and withstands aggressive organics that degrade other media. The PP housing sustains efficient flow on viscous samples and keeps the fluid path low in extractable contamination. For routine sample preparation across many methods, the syringe filter folds clarification into one disposable step.

Technical Specifications

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

Housing Specifications

• Optimized internal geometry minimizes backpressure in service
• Resists aqueous acids, bases, and alcohols in routine sample prep
• Reliable housing-to-membrane seal prevents bypass at rated pressure
• Low extractable contribution protects sensitive downstream analyses

Handling the harsh solvents your methods demand calls for a filter that holds up to the chemistry, pass after pass. 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.

• 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
• Aerosol Sampling - The hydrophobic nature of PTFE allows for gas venting and air monitoring applications in harsh environments
• Analytical Sample Prep - Optimized to ensure data integrity by effectively removing particulates before instrumental analysis
• Biological Fluid Analysis - Protects sensitive downstream instruments from removing particulates that can cause system failure
