LabExact Polyethersulfone (PES) Syringe Filters, 0.22 µm, 13 mm, 100/Pk - LE-IWT-ES10064
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. The PES membrane loads aqueous buffers with zero pre-wetting delay while staying stable across the pH 1 to 14 range and safeguards sterility by retaining bacteria at fine pore ratings. Polyolefin construction sheds virtually no extractable material into the sample while routing flow to minimize backpressure in service and resists degradation from routine sample matrices. Where bacterial contamination must stay out of the sample, manufacturer-tested retention keeps the instrument and downstream assay protected without a housing to maintain or clean.
Membrane Characteristics
- Non-hydrogen-bonding surface avoids the polar adsorption nylon's amide backbone causes
- PFAS extractables test non-detectable under EPA Method 537.1
- Absolute pore size rating holds consistent across every lot
- Antibody and protein samples pass through PES with minimal adsorptive loss
- Finest available pore ratings achieve aseptic-grade filtration performance
Housing Characteristics
- Polypropylene housing tolerates dilute aqueous acids, bases, and alcohols used in routine sample prep
- Polypropylene density near 0.90 g/cm3 keeps housing weight low relative to denser engineering plastics
- Thermal-bonded construction keeps adhesives out of the fluid path
- Housing tolerates elevated-temperature aqueous and solvent sample filtration up to about 80°C without softening
A particulate-laden aqueous sample makes the rest of your preparation unpredictable. Consistent aqueous clarification clears particulates without slowing your bench routine from the first sample of the day through the last.
