Whatman SKU: 10463505

Whatman ReZist PTFE Syringe Filters, 0.2 µm, 30 mm, 500/Pk - 10463505

Whatman's established manufacturing platform delivers the consistency and lot-level documentation that analytical laboratories require. A syringe filter holds its membrane in a leak-tight housing for clarification at the bench. The PTFE matrix handles concentrated acids and bases across demanding methods while staying chemically inert against solvents, acids, and alkalis and repels water while passing gases and solvents freely. The polypropylene housing contributes minimal extractables to the filtrate and stays inert across common laboratory solvents. When sterile or particle-free preparation matters at the bench, the syringe filter delivers it with minimal added handling.

Technical Specifications

• Chemically inert against aggressive solvents, strong acids, and alkalis
• Hydrophobic membrane repels water for gas, vent, and solvent filtration
• Absolute pore size rating gives consistent results across protocols
• Low extractables keep the chromatographic background clean
• Stable across a wide operating temperature range for demanding methods

Housing Specifications

• Thermal-bonded construction keeps adhesives out of the fluid path
• Resists aqueous acids, bases, and alcohols in routine sample prep
• Medical-grade polypropylene with broad chemical compatibility
• Reliable housing-to-membrane seal prevents bypass at rated pressure

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.

• 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
• 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
• Research & Development - Supports protocols that need to filter contaminants, providing the ability to optimize sample clarity
• Sample Clarification - Optimizing sample clarity via rapid filtering of contaminants to maintain high throughput in busy laboratories
