Pura Disc 13mm PVDF Syringe Filters, 0.2um, 50 Pk
Whatman SKU: 6791-1302

Whatman Puradisc PVDF Syringe Filters, 0.2 µm, 13 mm, 50/Pk - 6791-1302

Whatman's filtration expertise, refined across a century-plus of disciplined manufacturing, has made its name synonymous with laboratory-grade quality worldwide. At the sub-micron pore rating, a syringe filter delivers sterilizing-grade retention at the point of use. PVDF resists HPLC mobile phases, alcohols, and mild hydrocarbons and suits HPLC sample preparation with immediate, reliable uptake. The polypropylene housing maintains its geometry through sample runs up to 121°C while staying inert across common laboratory solvents and sheds virtually no extractable material into the sample. Where bacterial contamination must stay out of the sample, manufacturer-tested retention keeps the instrument and downstream assay protected without a housing to maintain or clean.

Technical Specifications

• Vapor-phase hydrogen peroxide decontamination cycles leave the membrane intact
• Autoclave sterilization cycles leave pore structure and flow performance intact
• Gamma irradiation sterilization causes no chain scission unlike polypropylene membranes
• Low extractables preserve a clean chromatographic baseline
• Cast membrane structure releases no fibers, unlike depth-media prefilters

Housing Specifications

• Burst pressure rating provides a wide safety margin above the rated maximum operating pressure.
• Translucent housing wall allows visual confirmation of sample flow during filtration
• Plasticizer-free polyolefin construction keeps the fluid path clean
• Medical-grade polypropylene with broad chemical compatibility

A clean particulate separation keeps your aqueous sample preparation dependable. Consistent aqueous clarification clears particulates without slowing your bench routine across the buffers and reagents your day-to-day prep depends on.

Hydrophobic

• Trace Analysis - Prevents non-specific binding in trace analysis, keeping low-concentration analytes in solution for reliable detection.
• Water Quality Monitoring - Clarifies environmental and drinking water samples ahead of turbidity, ion, or contaminant testing in monitoring programs.
• Pharmaceutical QC - Supports routine quality control testing by reliably filtering mild organic solvent mixtures and drug formulations daily.
• Pre-Blot Sample Prep - Ensures ultra-low protein binding for maximum sample recovery ahead of sensitive immunodetection protocols and assays.
• Biological Samples - Clarifies protein-rich solutions without loss of target molecules, preserving sample integrity for critical downstream assays.
• Dissolution Testing - Removes undissolved particles from timed USP 711 dissolution aliquots, preventing skewed potency and release results.
