Pura Disc 13mm PTFE Syringe Filters, 0.45um, 2000 Pk
Whatman SKU: 6766-1304

Whatman Puradisc PTFE Syringe Filters, 0.45 µm, 13 mm, 2000/Pk - 6766-1304

Whatman's established manufacturing platform delivers the consistency and lot-level documentation that analytical laboratories require. Syringe filters mount on a syringe to clarify a sample in a single manual pass. PTFE delivers absolute particle cutoff at the rated pore size and suits solvent filtration where other membranes fail. The polypropylene housing routes flow to minimize backpressure in service while resisting aqueous acids, bases, and alcohols and contributes minimal extractables to the filtrate. For routine sample preparation across many methods, the syringe filter folds clarification into one disposable step.

Technical Specifications

• Chemically inert against aggressive solvents, strong acids, and alkalis
• Low extractables keep the chromatographic background clean
• Hydrophobic membrane repels water for gas, vent, and solvent filtration
• Filters aggressive organic solvents without swelling or breakdown
• Stable across a wide operating temperature range for demanding methods

Housing Specifications

• Optimized internal geometry minimizes backpressure in service
• Low extractable contribution protects sensitive downstream analyses
• Reliable housing-to-membrane seal prevents bypass at rated pressure
• Thermal-bonded construction keeps adhesives out of the fluid path

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.

• 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
• Aerosol Sampling - The hydrophobic nature of PTFE allows for gas venting and air monitoring applications in harsh environments
• General Laboratory Filtration - Increases workflow efficiency by protecting analytical instruments without sacrificing flow rates
• Analytical Sample Prep - Optimized to ensure data integrity by effectively removing particulates before instrumental analysis
