Pura Disc FP 30mm Cellulose PTFE Syringe Filter, 0.2um, Sterile, 50 Pk
Whatman SKU: 10462300

Whatman Puradisc PTFE Syringe Filters, 0.2 µm, 30 mm, 50/Pk - 10462300

Whatman's expertise in cellulose, glass fiber, and polymeric membrane production guides material selection and quality control. A syringe filter holds its membrane in a leak-tight housing for clarification at the bench. The hydrophobic PTFE membrane provides bacterial retention in gas and vent streams while repelling water and passing gases and solvents freely and resists attack from the harshest process chemistries. The polycarbonate housing holds its form under elevated process pressure and resists damage during demanding use. For routine sample preparation across many methods, the syringe filter folds clarification into one disposable step.

Technical Specifications

• Absolute pore size rating gives consistent results across protocols
• Stable across a wide operating temperature range for demanding methods
• Hydrophobic membrane repels water for gas, vent, and solvent filtration
• Low extractables keep the chromatographic background clean
• Sterilizing-grade gas and vent filtration at sub-micron pore sizes

Housing Specifications

• High-impact-strength housing resists cracking under demanding handling
• Suited to aqueous samples, buffers, and reagents
• Reliable housing-to-membrane seal prevents bypass at rated pressure
• Sustains high operating pressures without deformation

Clarifying organic mobile phases before injection protects your chromatography while standing up to the solvent. Solvent-stream filtration handles the solvents and reagents your methods rely on from organic mobile-phase prep through reagent clarification.

• 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
• 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
• 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
