GD/X 13mm Syringe Filter, PVDF Filteration Medium, 0.45um (150 pcs)
Whatman SKU: 6873-1304

Whatman GD/X PVDF Syringe Filters, 0.45 µm, 13 mm, 150/Pk - 6873-1304

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. Many syringe filters ship with lot-specific quality documentation, giving analysts traceability that an ad hoc bulk filtration setup typically lacks. The surface modification reverses PVDF's natural affinity for protein adsorption while clarifying samples at the rated pore size and suits HPLC sample preparation with immediate, reliable uptake. Thermal-bonded PP construction leaves no seam for sample to bypass the membrane while maintaining a low-dead-volume internal flow path and stands firm against aqueous acids, bases, and alcohols during regular handling. Where bench-scale prep must move quickly from one sample to the next, each sample starts as clean as the last without a carry-over risk or a cleaning step between uses.

Membrane Characteristics

• Fluoropolymer chemistry resists microbial and fungal degradation
• Aqueous and HPLC samples wet the surface without pre-wetting
• Limiting oxygen index runs high, supporting flame resistance and low smoke
• Hydrochloric, dilute nitric, and up to 90% sulfuric acid cause no attack
• Ethylene oxide sterilization cycles leave pore integrity and flow performance intact

Housing Characteristics

• Minimal extractable release from the housing supports sensitive analytical work downstream
• PP housing rated to 121°C holds its geometry through high-temperature sample preparation and processing.
• Rigid polypropylene body maintains its geometry through routine filtration pressure
• Minimal intrinsic autofluorescence from the polypropylene housing supports background-sensitive fluorescence-based assay work downstream.

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.
