GD/X 13mm Syringe Filter, PVDF Filteration Medium, 0.45um (150 pcs)
Whatman SKU: 6872-1304

Whatman GD/X PVDF Syringe Filters, 0.45 µm, 13 mm, 150/Pk - 6872-1304

Whatman places a fibrous glass mat before the final membrane in every GD/X device, clearing a turbid sample in one pass through the same housing. Syringe filters span a wide range of membrane chemistries and pore sizes, so the format can be matched to the sample matrix and solvent system in use. PVDF delivers absolute cutoff at rated pore size while keeping HPLC analytes from adhering to the pore surface and suits HPLC sample preparation with immediate, reliable uptake. Polyolefin construction sheds virtually no extractable material into the sample and sustains its dimensional form through high-temperature filtration workflows. When chromatographic methods demand particle-free injections, the column stays clean from run to run, protecting method performance and column life.

Membrane Characteristics

• Hydrochloric, dilute nitric, and up to 90% sulfuric acid cause no attack
• Cast membrane structure releases no fibers, unlike depth-media prefilters
• Absolute pore rating ensures reproducible results between test runs
• Fluorinated polymer chemistry resists ozone, UV, and ionizing radiation
• Thin membrane structure sustains high flow for fast sample throughput

Housing Characteristics

• Medical-grade polypropylene with broad chemical compatibility
• Polypropylene housing withstands operating temperatures up to 121°C without softening or dimensional distortion.
• The seal formed against the membrane blocks bypass at rated operating pressure
• Minimal ionic background from the polypropylene housing supports ion chromatography and trace-metal ICP-MS sample preparation.

Clarify your routine aqueous samples in a single pass and cut down on juggling multiple filter types at the bench. General-purpose aqueous filtration supports the sample types you handle every day from reagent and buffer preparation through routine sample clarification.
