Sterile PES Syringe Filter - 0.22µm, 25mm, Hydrophilic, Luer-Lock, Lab Grade, 100/Pk
LabExact SKU: LE-IWT-ES10073

LabExact Polyethersulfone (PES) Syringe Filters, 0.22 µm, 25 mm, 100/Pk - LE-IWT-ES10073

Sterilizing-grade syringe filters deliver sterile-grade retention as a single-use format, eliminating the autoclaving and cleaning cycle a reusable sterile filtration setup would require. PES admits aqueous reagents on contact, skipping any surfactant rinse and handles strong bases across a broad aqueous range. The PP housing sustains efficient flow on viscous samples while providing a factory-sterilized fluid path suited to aseptic sample preparation and holds its seal true run after run. 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

• Inherent hydrophilicity allows instant aqueous wetting with no pre-wetting step
• Antibody and protein samples pass through PES with minimal adsorptive loss
• Finest available pore ratings achieve aseptic-grade filtration performance
• Sterilizing-grade PES membrane lots are challenge-tested against Brevundimonas diminuta to qualify 0.2 micron retention
• Chemical breadth spans alcohols, glycols, and aqueous buffers

Housing Characteristics

• Low moisture absorption keeps the housing dimensionally stable through humid storage and shipping
• Each housing is factory-sterilized and sealed individually to maintain sterility through the supply chain
• Resists stress cracking from aqueous salt and buffer solutions
• Minimal extractable release from the housing supports sensitive analytical work downstream

Particulates in your buffers and mobile phases shorten column life and unsettle your baselines. Upstream buffer clarification keeps your run from stalling on particulates that slipped through across routine and validated analytical methods.

• Biological Assays - Protects sensitive enzymatic and antibody-based assays from particulate interference without adsorbing critical reagents.
• Nucleic Acid Recovery - Processes DNA and RNA extracts with minimal nucleic acid adsorption, preserving yield on the hydrophilic PES surface.
• Pesticide Residue Testing - PES membranes improve polar pesticide recovery in food-safety LC-MS/MS testing versus hydrogen-bonding nylon.
• Sample Recovery - Minimizes sample loss in low-protein-binding applications, delivering high yield for precious or rare biological specimens.
• Media Preparation - Facilitates rapid sterilization of tissue culture additives, lowering contamination risk during sensitive laboratory work.
• Organic Carbon Testing - Clarifies water samples ahead of DOC and UV254 analysis while keeping organic carbon adsorption to the membrane minimal.
