Pura Disc 13mm PTFE Syringe Filters, 0.2um, 500 Pk
Whatman SKU: 6783-1302

Whatman Puradisc PTFE Syringe Filters, 0.2 µm, 13 mm, 500/Pk - 6783-1302

Whatman's established manufacturing platform delivers the consistency and lot-level documentation that analytical laboratories require. Syringe filters give the analyst a single-use device for clarifying samples right at the bench. Hydrophobic PTFE blocks aqueous ingress in vent and gas applications while handling concentrated acids and bases and stays chemically inert against solvents, acids, and alkalis. The PP housing keeps the fluid path low in extractable contamination and resists degradation from routine sample matrices. When sterile or particle-free preparation matters at the bench, the syringe filter delivers it with minimal added handling.

Technical Specifications

• Stable across a wide operating temperature range for demanding methods
• Sterilizing-grade gas and vent filtration at sub-micron pore sizes
• Low extractables keep the chromatographic background clean
• Filters aggressive organic solvents without swelling or breakdown
• Chemically inert against aggressive solvents, strong acids, and alkalis

Housing Specifications

• Reliable housing-to-membrane seal prevents bypass at rated pressure
• Resists aqueous acids, bases, and alcohols in routine sample prep
• Medical-grade polypropylene with broad chemical compatibility
• Optimized internal geometry minimizes backpressure in service

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.

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
• Biological Fluid Analysis - Protects sensitive downstream instruments from filtering contaminants that can cause system failure
• Sample Clarification - Optimizing sample clarity via rapid filtering of contaminants to maintain high throughput in busy laboratories
