GVS SKU: GF25BNPGN004AT01PF

GVS ABLUO Nylon Syringe Filters, 0.45 µm, 25 mm, 10/Pk - GF25BNPGN004AT01PF

Every GVS syringe filter passes an integrity test confirming proper fit and weld, verification that the assembly is sealed against filter bypass. Many syringe filters ship with lot-specific quality documentation, giving analysts documented traceability beyond what an ad hoc bulk filtration setup typically provides. The nylon membrane holds dimensional stability under rated backpressure while resisting alkaline buffer systems and ships in economical bulk non-sterile packaging. The polypropylene housing holds its seal true run after run and sustains efficient flow on viscous samples. When chromatographic methods demand particle-free injections, the column stays clean from run to run, protecting method performance and column life.

Selected specifically for PFAS-free sample preparation, the filter avoids the fluoropolymer components that can release per- and polyfluoroalkyl substances into an aqueous filtrate during analysis. Backed by independent PFAS-free verification, the device gives analysts confidence that a detected per- and polyfluoroalkyl signal originates in the sample rather than the filter, even at parts-per-trillion levels. Across regulated PFAS testing programs, the clean filtration background keeps reported results tied to the sample rather than to the labware used in the preparation workflow.

Prefiltration

• Naturally hydrophilic borosilicate fiber wets quickly with aqueous samples
• Glass fiber prefilter stage sustains flow through particle-laden, hard-to-filter samples
• High dirt-holding capacity suits very turbid, high-solids sample loads
• Depth-loading glass fiber matrix captures particulate throughout its full thickness

Membrane Characteristics

• Synthetic polyamide backbone resists microbial and enzymatic degradation unlike cellulose membranes
• Non-fibrous membrane structure resists media shedding into the filtrate
• Hydrophilic surface takes up aqueous samples with no pre-wetting
• Low extractable contribution to sensitive analytical preparations
• Compatible with most HPLC mobile phases for sample clarification

Housing Characteristics

• Burst pressure rating provides a wide safety margin above the rated maximum operating pressure
• Housing rated for warm-sample filtration above standard laboratory temperature without softening or seal loss
• Inert polyolefin wall contributes minimal sample adsorption to the filtrate
• Withstands standard 121°C steam autoclave cycles without softening or structural distortion

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 across your water-analysis and general analytical workflows.

• Solvent Filtering - Supports clarification of ester-based and alcohol solvents with precision during routine laboratory sample processing.
• Drinking Water Analysis - Clarifies tap and source water samples ahead of metals, nitrate, and trace-contaminant compliance testing.
• QuEChERS Cleanup - Clarifies acetonitrile food extracts after dispersive cleanup, protecting GC-MS and LC-MS systems during pesticide screening.
• Buffer Filtration - Delivers high mechanical strength for efficient clarification of alkaline buffers and aqueous reagents in the lab.
• HPLC Pump Protection - Filters reservoir solvent to prevent particulates from abrading pump check valves and seals over time.
• HPLC Sample Prep - Clarifies mixed aqueous and organic solvents to ensure stable baselines and protect chromatography columns from clogging.
