GD/X 13mm Syringe Filter, PVDF Filteration Medium, 0.2um (150 pcs)
Whatman SKU: 6872-1302

Whatman GD/X PVDF Syringe Filters, 0.2 µm, 13 mm, 150/Pk - 6872-1302

Whatman ties GD/X prefiltration performance to one closely held fiber-grade standard applied at every production run, keeping results repeatable from one manufacturing lot to the next. A sterilizing-grade syringe filter carries manufacturer bacterial retention testing built into the design, giving analysts documented sterile-grade performance without repeating that testing in-house for the format. The PVDF membrane delivers bacterial retention at the rated pore size and shields hydrophobic backbone from protein with surface modification. Polypropylene construction resists chemical degradation from routine sample matrices while maintaining dimensional stability through sample runs at temperatures up to 121°C and holds its seal true run after run. 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.

Membrane Characteristics

• Vapor-phase hydrogen peroxide decontamination cycles leave the membrane intact
• Cast membrane structure releases no fibers, unlike depth-media prefilters
• Ethylene oxide sterilization cycles leave pore integrity and flow performance intact
• Aqueous and HPLC samples wet the surface without pre-wetting
• Adsorptive loss of HPLC analytes stays immeasurably low

Housing Characteristics

• Stable across the full aqueous pH range in routine sample work
• Rigid polypropylene body maintains its geometry through routine filtration pressure
• PP housing rated to 121°C holds its geometry through high-temperature sample preparation and processing.
• Impact-tolerant polypropylene body withstands routine bench handling without damage

A clean particulate separation keeps your aqueous sample preparation dependable. General-purpose aqueous filtration supports the sample types you handle every day so you can standardize one filter across most aqueous methods.
