GVS ABLUO Glass Fiber (GF) Syringe Filters, 3.1 µm, 25 mm, 100/Pk - FJ25BNPGF031AH01PF

GVS produces its glass fiber depth media at the same United States facilities that manufacture its polymer membrane lineup. Sample preparation for chromatography often ends with a syringe filter on the path to the vial. Naturally hydrophilic glass fiber wets rapidly with aqueous samples while offering broad chemical compatibility and sustains high dirt-loading capacity through depth filtration. Polypropylene construction maintains a low-dead-volume internal flow path while leaving no seam for sample to bypass the membrane and stands firm against aqueous acids, bases, and alcohols during regular handling. 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.

Free of per- and polyfluoroalkyl substances, the filter uses only fluoropolymer-free wetted materials that contribute no PFAS of their own to an aqueous filtrate during routine sample preparation. Carrying independent third-party PFAS-free validation, the device shields low-level per- and polyfluoroalkyl determinations from the background contamination an ordinary filter can contribute during routine sample filtration. 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.

Membrane Characteristics

• Surface silanol groups attract water molecules for immediate aqueous wetting
• Dimensionally stable fiber mat resists compaction under sustained backpressure or vacuum
• High dirt-loading capacity extends filterable sample volume on turbid, particle-laden samples
• Reduces bioburden and particulate load ahead of sterilizing-grade filtration
• Continuous glass fiber microstructure supports even flow distribution across the filter face

Housing Characteristics

• Low moisture absorption keeps the housing dimensionally stable through humid storage and shipping
• Minimal ionic background from the polypropylene housing supports ion chromatography and trace-metal ICP-MS sample preparation
• Impact-tolerant polypropylene body withstands routine bench handling without damage
• Resists stress cracking from aqueous salt and buffer solutions

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.
