LabExact Polyethersulfone (PES) Syringe Filters, 0.45 µm, 13 mm, 100/Pk - LE-IWT-ES10207
Individually packaged and pre-tested, a syringe filter needs no functional check before use the way a shared reusable holder does. PES holds consistent absolute retention at the rated pore size while handling strong bases across a broad aqueous range and loads aqueous buffers with zero pre-wetting delay. Thermal-bonded PP construction leaves no seam for sample to bypass the membrane while keeping sample purity intact through the filtration pass and stays inert across common laboratory solvents. When method reproducibility rests on consistent sample prep, syringe filtration holds that standard injection after injection.
Membrane Characteristics
- Inherent hydrophilicity allows instant aqueous wetting with no pre-wetting step
- Compatibility spans both nucleic acid and protein-based filtration
- Aromatic sulfone backbone underlies stability across the full pH range
- Non-hydrogen-bonding surface avoids the polar adsorption nylon's amide backbone causes
- Absolute pore size rating holds consistent across every lot
Housing Characteristics
- Stable across the full aqueous pH range in routine sample work
- Rated operating pressure supports filtration of high-resistance and viscous samples without housing distortion
- Housing tolerates elevated-temperature aqueous and solvent sample filtration up to about 80°C without softening
- Minimal extractable release from the housing supports sensitive analytical work downstream
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.
