Pura Disc 13mm PTFE Syringe Filters, 0.45um, 500 Pk
Whatman SKU: 6783-1304

Whatman Puradisc PTFE Syringe Filters, 0.45 µm, 13 mm, 500/Pk - 6783-1304

Whatman applies the same process controls across its filtration portfolio, verifying rated performance at the production lot level. Sample preparation for chromatography often ends with a syringe filter on the path to the vial. Hydrophobic PTFE repels water while passing gases and solvents freely and handles concentrated acids and bases. Polypropylene construction maintains housing integrity through the filtration run and routes flow to minimize backpressure in service. Where small-volume samples must reach the instrument clean, syringe filtration clears particulates in a single pass.

Technical Specifications

• Low extractables keep the chromatographic background clean
• 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
• Stable across a wide operating temperature range for demanding methods

Housing Specifications

• Reliable housing-to-membrane seal prevents bypass at rated pressure
• Thermal-bonded construction keeps adhesives out of the fluid path
• Low extractable contribution protects sensitive downstream analyses
• Medical-grade polypropylene with broad chemical compatibility

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.

• 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
• Cryogenic Fluids - Remains functional and integral even at extreme temperatures, protecting sensitive equipment from damage
• Particulate Removal - Designed for removing particulates, this filter aids in protecting analytical instruments across diverse sample types
• Quality Control Testing - Optimized for delivering reproducible results by removing particulates in standard pharmaceutical protocols
