PTFE Syringe Filters w/ GF Prefilter, 0.7/0.22um, 25mm, Luer-Lok/Luer Slip, Nonsterile, 500/Pk
GVS SKU: GF25BNPGT002AD01

GVS ABLUO Water-Wettable PTFE Syringe Filters, 0.22 µm, 25 mm, 500/Pk - GF25BNPGT002AD01

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. Water-wettable PTFE delivers sterile-grade retention at rated sub-micron size while filtering aqueous and organic samples in one membrane and resists strong acids, alkalis, and organic solvents. MBS construction stays dimensionally stable through the filtration run while tolerating aqueous acids, bases, and alcohols during standard prep and shows the sample as it moves through. For workflows requiring validated sterile-grade performance, point-of-use retention meets it without a separate sterilization step.

Prefiltration

• Naturally hydrophilic borosilicate fiber wets quickly with aqueous samples
• Depth-loading glass fiber matrix captures particulate throughout its full thickness
• Added glass fiber stage extends usable throughput by delaying membrane clogging
• Two-stage construction pairs a borosilicate glass fiber prefilter with the downstream membrane

Membrane Characteristics

• The fluorocarbon backbone's carbon-fluorine bonds rank among the strongest in organic chemistry
• The fluoropolymer's chemical inertness keeps proteins stable in solution
• Absolute-rated pore structure delivers repeatable particle capture batch to batch
• Minimal extractable material leaches from the membrane during use
• The membrane's chemical compatibility extends to aggressive organic solvents beyond aqueous solutions

Housing Characteristics

• Hard methacrylate surface resists scuffing through repeated handling
• Phthalate-free composition keeps a common LC-MS and GC-MS contaminant out of sample workflows
• Creep-resistant matrix holds seal geometry through the filtration run
• Luer-compatible MBS housing connects directly to standard syringe tips for hand-pressure filtration

An unfiltered buffer can foul your instrument and interrupt a run mid-sequence. Upstream buffer clarification keeps your run from stalling on particulates that slipped through while keeping the filtrate analytically clean.
