Pura Disc 25mm PTFE Syringe Filters, 1.0um, 50 Pk
Whatman SKU: 6784-2510

Whatman Puradisc PTFE Syringe Filters, 1 µm, 25 mm, 50/Pk - 6784-2510

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. The PTFE membrane clarifies solvent streams at the rated pore size while resisting attack from the harshest process chemistries and suits gas, vent, and solvent-stream filtration. The polypropylene housing contributes minimal extractables to the filtrate while resisting aqueous acids, bases, and alcohols and maintains a low-dead-volume internal flow path. Where small-volume samples must reach the instrument clean, syringe filtration clears particulates in a single pass.

Technical Specifications

• Absolute pore size rating gives consistent results across protocols
• Stable across a wide operating temperature range for demanding methods
• Filters aggressive organic solvents without swelling or breakdown
• Chemically inert against aggressive solvents, strong acids, and alkalis
• Low extractables keep the chromatographic background clean

Housing Specifications

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

Handling the harsh solvents your methods demand calls for a filter that holds up to the chemistry, pass after pass. Solvent-stream filtration handles the solvents and reagents your methods rely on across the organic solvents and harsh reagents your methods use.

Wettability

Hydrophobic

• Cryogenic Fluids - Remains functional and integral even at extreme temperatures, protecting sensitive equipment from damage
• Organic Mobile Phases - Ideal for filtering 100% organic solvents in HPLC and GC workflows without any membrane degradation
• 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
• Biological Fluid Analysis - Protects sensitive downstream instruments from removing high particulate loads that can cause system failure
• Environmental Monitoring - Ideal for removing high particulate loads in water and wastewater analysis to ensure regulatory compliance
