Pura Disc 25mm PTFE Syringe Filters, 1.0um, 1000 Pk
Whatman SKU: 6798-2510

Whatman Puradisc PTFE Syringe Filters, 1 µm, 25 mm, 1000/Pk - 6798-2510

Whatman applies over a century of filtration media expertise, manufacturing under the quality standards that established its products as global laboratory references. At the point of sample preparation, a syringe filter removes particulates before the sample reaches the instrument. PTFE filters aggressive organic solvents without swelling or breakdown and resists attack from the harshest process chemistries. Polypropylene construction maintains a low-dead-volume internal flow path and holds extractables low for sensitive analyses. When chromatographic methods demand particle-free injections, point-of-use syringe filtration clarifies the sample before it reaches the column.

Technical Specifications

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

Housing Specifications

• Low extractable contribution protects sensitive downstream analyses
• Reliable housing-to-membrane seal prevents bypass at rated pressure
• Medical-grade polypropylene with broad chemical compatibility
• 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 from reaction mixtures and crude extracts through final analysis. Ask our friendly customer service team to confirm the pore size, membrane, and sterility options your filtration application calls for.

• 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
• Quality Control Testing - Delivers reproducible results by removing high particulate loads in standard pharmaceutical protocols
• Analytical Sample Prep - Ensures data integrity by effectively removing high particulate loads before instrumental analysis
