GVS ABLUO Polyethersulfone (PES) Syringe Filters, 0.45 µm, 25 mm, 100/Pk - FJ25BNPPS004AH01PF

GVS syringe filters come out of the company's own United States facilities, built under the production controls its quality management system requires. Many syringe filters ship with lot-specific quality documentation, giving analysts documented traceability beyond what an ad hoc bulk filtration setup typically provides. The PES matrix tolerates aliphatic alcohols, glycols, and aqueous buffers and clears particulate matter above its coarse cutoff threshold. The polypropylene housing resists aqueous acids, bases, and alcohols in routine use while leaving no seam for sample to bypass the membrane and routes flow to minimize backpressure in service. When method reproducibility rests on consistent sample prep, syringe filtration holds that standard injection after injection.

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. Validated PFAS-free under independent laboratory testing, the filter adds no measurable per- and polyfluoroalkyl background to the trace analytes a sensitive method works to quantify. 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

• Inherent hydrophilicity allows instant aqueous wetting with no pre-wetting step
• Non-ionic surface avoids charge-driven protein binding of positively and negatively charged membrane types
• Ionic extractables from the membrane stay very low
• Aromatic sulfone backbone underlies stability across the full pH range
• Compatibility spans both nucleic acid and protein-based filtration

Housing Characteristics

• Withstands standard 121°C steam autoclave cycles without softening or structural distortion
• Polypropylene housing tolerates dilute aqueous acids, bases, and alcohols used in routine sample prep
• Plasticizer-free polyolefin construction keeps the fluid path clean
• Polypropylene density near 0.90 g/cm3 keeps housing weight low relative to denser engineering plastics

Juggling several filter types for one routine clarification eats up your bench time. Consistent aqueous clarification clears particulates without slowing your bench routine the same way every time you run it.

• Life Science Prep - Speeds processing of viscous biological solutions, improving laboratory workflow efficiency during busy sample prep days.
• Biological Assays - Protects sensitive enzymatic and antibody-based assays from particulate interference without adsorbing critical reagents.
• Sample Recovery - Minimizes sample loss in low-protein-binding applications, delivering high yield for precious or rare biological specimens.
• 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.
• Urine Drug Screening - Clarifies protein-poor urine samples for dilute-and-shoot LC-MS/MS toxicology testing without adsorbing target drug analytes.
