GD/X 13mm Syringe Filter, Nylon Filteration Medium, 0.45um (150 pcs)
Whatman SKU: 6871-1304

Whatman GD/X Nylon Syringe Filters, 0.45 µm, 13 mm, 150/Pk - 6871-1304

Whatman pairs a borosilicate fiber depth layer with the finishing membrane inside every GD/X unit, a construction meant to process loads heavy enough to clog a conventional one-stage filter. Because each syringe filter is dedicated to one sample, a failed or contaminated filtration never delays the next analyst's run waiting on a shared holder. Nylon wets on contact with aqueous samples while delivering sharp particle cutoff at the rated pore size and fits routine analytical sample preparation. The polypropylene housing routes flow to minimize backpressure in service and holds its seal true run after run. 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

• Layered prefiltration sustains flow through turbid, particulate-laden samples
• Resin melting point runs near 264°C
• Common ketone solvents, including acetone, methyl ethyl ketone, and methyl isobutyl ketone, cause no attack
• Autoclaving at 121°C for 30 minutes leaves pore structure intact
• Solvent compatibility extends to both acetonitrile and methanol

Housing Characteristics

• Withstands standard 121°C steam autoclave cycles without softening or structural distortion
• Polypropylene density near 0.90 g/cm3 keeps housing weight low relative to denser engineering plastics
• Minimal intrinsic autofluorescence from the polypropylene housing supports background-sensitive fluorescence-based assay work downstream.
• Translucent housing wall allows visual confirmation of sample flow during filtration

Filtering buffers, reagents, and aqueous samples keeps your preparation moving and consistent. Consistent aqueous clarification clears particulates without slowing your bench routine the same way every time you run it.
