LabExact Tri-Layer Nylon Syringe Filters, 0.45 µm, 25 mm, 100/Pk - LE-IWT-ES10400

A syringe filter's small hold-up volume limits sample loss, a meaningful difference when working with a limited or precious sample. Nylon pairs with a glass-fiber prefilter for turbid samples while shipping in economical bulk non-sterile packaging and screens out particles wider than the membrane's rated diameter. The PP housing sustains efficient flow on viscous samples while shedding virtually no extractable material into the sample and leaves no seam for sample to bypass the membrane. Where analytical results depend on clean samples, the preparation step stays consistent from sample to sample through a pre-tested syringe filter.

Membrane Characteristics

• Non-sterile format suits HPLC and GC sample clarification
• Moisture-plasticized amide linkages raise membrane impact toughness over dry resin
• Solvent compatibility extends to both acetonitrile and methanol
• Integrated glass-fiber prefilter increases dirt-holding capacity
• Filtration clarifies HPLC mobile phase buffers of particulates

Housing Characteristics

• Resists stress cracking from aqueous salt and buffer solutions
• Impact-tolerant polypropylene body withstands routine bench handling without damage
• Minimal extractable release from the housing supports sensitive analytical work downstream
• Inert polyolefin wall contributes minimal sample adsorption to the filtrate

Particulates in your buffers, reagents, and aqueous samples slow your preparation and throw off its consistency. General-purpose aqueous filtration supports the sample types you handle every day from reagent and buffer preparation through routine sample clarification.
