PES Syringe Filters w/ Glass Fiber Prefilter, 0.45um, 25mm, Luer-Lok/Luer Slip, Nonsterile, 10/Pk
GVS SKU: GF25BNPGS004AT01PF

GVS ABLUO Polyethersulfone (PES) Syringe Filters, 0.45 µm, 25 mm, 10/Pk - GF25BNPGS004AT01PF

GVS syringe filters come out of the company's own United States facilities, built under the production controls its quality management system requires. Syringe filters span a wide range of membrane chemistries and pore sizes, so the format can be matched to the sample matrix and solvent system in use. PES pairs fast flow with reduced protein and antibody adsorption and clears particulate matter above its coarse cutoff threshold. The polypropylene housing routes flow to minimize backpressure in service while preserving sample chemistry across the flow path and stands firm against aqueous acids, bases, and alcohols during regular handling. When method reproducibility rests on consistent sample prep, syringe filtration holds that standard injection after injection.

PFAS-free across the wetted path, the device introduces no per- and polyfluoroalkyl substances of its own into the filtrate as the sample passes through the housing and membrane. 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. In environmental, wastewater, and food-safety PFAS testing, reported per- and polyfluoroalkyl concentrations reflect the sample itself rather than the filter used to prepare it for analysis.

Prefiltration

• Depth-loading glass fiber matrix captures particulate throughout its full thickness
• Naturally hydrophilic borosilicate fiber wets quickly with aqueous samples
• High dirt-holding capacity suits very turbid, high-solids sample loads
• Added glass fiber stage extends usable throughput by delaying membrane clogging

Membrane Characteristics

• Chemical breadth spans alcohols, glycols, and aqueous buffers
• Non-ionic surface avoids charge-driven protein binding of positively and negatively charged membrane types
• Sulfone backbone's hydrolytic stability tolerates repeated autoclave steam sterilization cycles
• Ionic extractables from the membrane stay very low
• PFAS extractables test non-detectable under EPA Method 537.1

Housing Characteristics

• Plasticizer-free polyolefin construction keeps the fluid path clean
• Housing tolerates elevated-temperature aqueous and solvent sample filtration up to about 80°C without softening
• 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

Particulates in your buffers, reagents, and aqueous samples slow your preparation and throw off its consistency. Consistent aqueous clarification clears particulates without slowing your bench routine across the buffers and reagents your day-to-day prep depends on.

• Pesticide Residue Testing - PES membranes improve polar pesticide recovery in food-safety LC-MS/MS testing versus hydrogen-bonding nylon.
• Serum Filtration - Clarifies serum and plasma samples quickly while retaining critical proteins needed for accurate downstream analytical testing.
• Organic Carbon Testing - Clarifies water samples ahead of DOC and UV254 analysis while keeping organic carbon adsorption to the membrane minimal.
• PFAS Water Testing - PES filters process aqueous samples for EPA Method 1633A PFAS testing without added fluorinated background.
• Nucleic Acid Recovery - Processes DNA and RNA extracts with minimal nucleic acid adsorption, preserving yield on the hydrophilic PES surface.
• Urine Drug Screening - Clarifies protein-poor urine samples for dilute-and-shoot LC-MS/MS toxicology testing without adsorbing target drug analytes.
