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 stages multiple glass fiber layers inside the GD/X cartridge to intercept particles in progressive steps, leaving only the smallest fraction to reach the tightly rated final membrane. Many syringe filters ship with lot-specific quality documentation, giving analysts traceability that an ad hoc bulk filtration setup typically lacks. Nylon adds a layered glass-fiber prefilter for particulate-laden samples while resisting particle shedding across the run and screens out particles wider than the membrane's rated diameter. Polypropylene construction holds its dimensional form through high-temperature sample preparation and routes flow to minimize backpressure in service. Where small-volume samples must reach the instrument clean, low hold-up volume keeps sample loss minimal while the instrument stays protected from particulate damage.

Membrane Characteristics

• Integrated glass-fiber prefilter increases dirt-holding capacity
• Common ketone solvents, including acetone, methyl ethyl ketone, and methyl isobutyl ketone, cause no attack
• Absolute pore size rating holds consistent across every protocol
• Amorphous-crystalline nylon blend composition doubles membrane burst strength over homopolymer nylon
• Ester- and alcohol-resistant across common laboratory sample preparations

Housing Characteristics

• Low moisture absorption keeps the housing dimensionally stable through humid storage and shipping
• Burst pressure rating provides a wide safety margin above the rated maximum operating pressure.
• Plasticizer-free polyolefin construction keeps the fluid path clean
• 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 from reagent and buffer preparation through routine sample clarification. Bulk pricing kicks in on larger filtration orders, so ask the Tisch Scientific team for a quote.
