GVS ABLUO Nylon Syringe Filters, 0.22 µm, 25 mm, 10/Pk - GF25BNPGN002AT01PF

ISO quality system controls extend across GVS's own membrane casting and syringe filter assembly, both stages handled in-house. A sterilizing-grade syringe filter delivers point-of-use sterile filtration in a single-use format, without the housing and gasket maintenance a reusable stainless steel filter holder requires. The nylon membrane holds dimensional stability under rated backpressure while accepting water-based reagents without surfactant conditioning and stays stable across pH 3 to 12. The polypropylene housing presses snugly against the membrane during the pass while standing firm against aqueous acids, bases, and alcohols during regular handling and routes flow to minimize backpressure in service. When sample preparation calls for a sterile filtrate at the point of injection, sterilizing-grade absolute retention delivers it directly, protecting the analytical method from microbial interference.

With no PFAS-bearing fluoropolymers anywhere in the flow path, per- and polyfluoroalkyl substances stay clear of the sample from the inlet through to the collected filtrate. Independent testing documents the PFAS-free performance, so the filtration step itself does not become a source of the contaminants a trace method is designed to find. For laboratories quantifying trace PFAS under EPA Method 1633 in environmental and wastewater matrices, the clean filtration background preserves data quality from sample preparation through final instrumental detection.

Prefiltration

• Two-stage construction pairs a borosilicate glass fiber prefilter with the downstream membrane
• Glass fiber prefilter stage sustains flow through particle-laden, hard-to-filter samples
• Depth-loading glass fiber matrix captures particulate throughout its full thickness
• Added glass fiber stage extends usable throughput by delaying membrane clogging

Membrane Characteristics

• Non-sterile format suits HPLC and GC sample clarification
• Moisture-plasticized amide linkages raise membrane impact toughness over dry resin
• Amorphous-crystalline nylon blend composition doubles membrane burst strength over homopolymer nylon
• Polar amide backbone gives high native affinity for nucleic acids
• Common ketone solvents, including acetone, methyl ethyl ketone, and methyl isobutyl ketone, cause no attack

Housing Characteristics

• Plasticizer-free polyolefin construction keeps the fluid path clean
• Housing rated for warm-sample filtration above standard laboratory temperature without softening or seal loss
• Minimal extractable release from the housing supports sensitive analytical work downstream
• Translucent housing wall allows visual confirmation of sample flow during filtration

Particulates that reach your column with the sample foul the frits and shorten its life. Upstream sample clarification keeps your separations clean and reproducible from sample preparation through final injection.
