ReZist Syringe Filter, 30mm, PTFE, 1.0um, 100/Pk
Whatman SKU: 10463523

Whatman ReZist PTFE Syringe Filters, 1 µm, 30 mm, 100/Pk - 10463523

Whatman's established manufacturing platform delivers the consistency and lot-level documentation that analytical laboratories require. Under hand pressure from the syringe, the membrane captures particulates as the sample passes through. PTFE suits solvent and reagent filtration where other membranes fail while delivering absolute particle cutoff at the rated pore size and stays chemically inert against solvents, acids, and alkalis. Polypropylene construction holds extractable contribution low for sensitive analyses while sustaining efficient flow on viscous samples and stays inert across common laboratory solvents. For routine sample preparation across many methods, the syringe filter folds clarification into one disposable step.

Technical Specifications

• Hydrophobic membrane repels water for gas, vent, and solvent filtration
• Low extractables keep the chromatographic background clean
• Chemically inert against aggressive solvents, strong acids, and alkalis
• Filters aggressive organic solvents without swelling or breakdown
• Absolute pore size rating gives consistent results across protocols

Housing Specifications

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

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 so your downstream method starts with a clean sample.

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
• 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
• Quality Control Testing - Delivers reproducible results by removing high particulate loads in standard pharmaceutical protocols
• Particulate Removal - Designed for removing high particulate loads, this filter aids in preventing premature clogging across diverse sample types
