GD/X 13mm Syringe Filter, Nylon Filteration Medium, 0.45um (150 pcs)
Whatman SKU: 6870-1304

Whatman GD/X Nylon Syringe Filters, 0.45 µm, 13 mm, 150/Pk - 6870-1304

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. Sample preparation for chromatography often ends with a syringe filter on the path to the vial. Nylon includes built-in prefilter sustaining flow on high-particulate samples while accepting water-based reagents without surfactant conditioning and stays stable across pH 3 to 12. Polypropylene construction maintains a low-dead-volume internal flow path while keeping sample purity intact through the filtration pass and stays inert across common laboratory solvents. Where bench-scale prep must move quickly from one sample to the next, the syringe filter adds a clarification step without slowing the workflow.

Technical Specifications

• Layered prefiltration sustains flow through turbid, particulate-laden samples
• Nylon's synthetic polyamide backbone resists the microbial and enzymatic degradation that can compromise cellulose-based membrane materials during extended aqueous processing.
• Low extractable contribution to sensitive analytical preparations
• Alkaline-resistant across a broad range of aqueous buffers
• Nylon membrane filtration of HPLC mobile phase buffers removes particulates before they abrade pump seals or clog injector valves

Housing Specifications

• Resists stress cracking from aqueous salt and buffer solutions
• Optimized internal geometry minimizes backpressure in service
• Minimal ionic background from the polypropylene housing supports ion chromatography and trace-metal ICP-MS sample preparation.
• Rigid polypropylene body maintains its geometry through routine filtration pressure

Clarify your routine aqueous samples in a single pass and cut down on juggling multiple filter types at the bench. Consistent aqueous clarification clears particulates without slowing your bench routine from the first sample of the day through the last. Ask about a quality certificate, lot documentation, or a blanket-order quote for your filtration order at any time.
