PES Syringe Filters, 0.22um, 25mm, Luer-Lok/Luer Slip, Nonsterile, Clear, 100/Pk
GVS SKU: FJ25BNPPS002AH01

GVS ABLUO Polyethersulfone (PES) Syringe Filters, 0.22 µm, 25 mm, 100/Pk - FJ25BNPPS002AH01

Class 100,000 cleanroom conditions govern GVS's syringe filter and membrane production, held to the specifications its quality management system defines. A sterilizing-grade syringe filter carries manufacturer bacterial retention testing built into the design, giving analysts documented sterile-grade performance without repeating that testing in-house for the format. PES's native polysulfone needs a surface treatment before it wets and reaches sterile-grade performance while protecting analyte yield. The polypropylene housing routes flow to minimize backpressure in service while leaving no seam for sample to bypass the membrane and delivers a chemically clean filtrate to the downstream step. When sample preparation calls for a sterile filtrate at the point of injection, sterilizing-grade absolute retention delivers it directly, protecting the analytical method from microbial interference.

Membrane Characteristics

• Aromatic sulfone backbone underlies stability across the full pH range
• Mechanical strength keeps the matrix intact under vacuum or pressure
• Ionic extractables from the membrane stay very low
• Sterilizing-grade PES membrane lots are challenge-tested against Brevundimonas diminuta to qualify 0.2 micron retention
• Absolute pore size rating holds consistent across every lot

Housing Characteristics

• Housing tolerates elevated-temperature aqueous and solvent sample filtration up to about 80°C without softening
• Polypropylene density near 0.90 g/cm3 keeps housing weight low relative to denser engineering plastics
• Medical-grade polypropylene with broad chemical compatibility
• The seal formed against the membrane blocks bypass at rated operating pressure

An unfiltered buffer can foul your instrument and interrupt a run mid-sequence. Reliable particulate removal protects your instruments and your data before each HPLC, UHPLC, and dissolution run. Request a quote on bulk pricing for larger filtration orders from the Tisch Scientific team.

Hydrophilic

• Media Preparation - Facilitates rapid sterilization of tissue culture additives, lowering contamination risk during sensitive laboratory work.
• Urine Drug Screening - Clarifies protein-poor urine samples for dilute-and-shoot LC-MS/MS toxicology testing without adsorbing target drug analytes.
• Organic Carbon Testing - Clarifies water samples ahead of DOC and UV254 analysis while keeping organic carbon adsorption to the membrane minimal.
• Biological Assays - Protects sensitive enzymatic and antibody-based assays from particulate interference without adsorbing critical reagents.
• Pesticide Residue Testing - PES membranes improve polar pesticide recovery in food-safety LC-MS/MS testing versus hydrogen-bonding nylon.
• Cell Culture - Reduces the risk of mycoplasma contamination in growth media, supporting healthier cell lines and more reliable experimental outcomes.
