LabExact Polyethersulfone (PES) Syringe Filters, 0.22 µm, 13 mm, 100/Pk - LE-IWT-ES10071

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 while pairing sterile-grade filtration with minimal sample loss and stays stable across the pH 1 to 14 range. Polypropylene construction resists chemical degradation from routine sample matrices 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

• Non-hydrogen-bonding surface avoids the polar adsorption nylon's amide backbone causes
• Ionic extractables from the membrane stay very low
• Aromatic sulfone backbone underlies stability across the full pH range
• PFAS extractables test non-detectable under EPA Method 537.1
• Finest available pore ratings achieve aseptic-grade filtration performance

Housing Characteristics

• Stable across the full aqueous pH range in routine sample work
• Minimal ionic background from the polypropylene housing supports ion chromatography and trace-metal ICP-MS sample preparation
• Withstands standard 121°C steam autoclave cycles without softening or structural distortion
• Optimized internal geometry minimizes backpressure in service

Fine particulates that slip through raise your system backpressure and bring maintenance forward. Reliable particulate removal protects your instruments and your data before each HPLC, UHPLC, and dissolution run.

• Biological Assays - Protects sensitive enzymatic and antibody-based assays from particulate interference without adsorbing critical reagents.
• Organic Carbon Testing - Clarifies water samples ahead of DOC and UV254 analysis while keeping organic carbon adsorption to the membrane minimal.
• Pesticide Residue Testing - PES membranes improve polar pesticide recovery in food-safety LC-MS/MS testing versus hydrogen-bonding nylon.
• Urine Drug Screening - Clarifies protein-poor urine samples for dilute-and-shoot LC-MS/MS toxicology testing without adsorbing target drug analytes.
• Media Preparation - Facilitates rapid sterilization of tissue culture additives, lowering contamination risk during sensitive laboratory work.
• Nucleic Acid Recovery - Processes DNA and RNA extracts with minimal nucleic acid adsorption, preserving yield on the hydrophilic PES surface.
