Sterile PES Syringe Filter, 0.45µm, 25mm, Hydrophilic Luer-Lock, Tissue Culture - 100/pk
LabExact SKU: LE-IWT-ES10074

LabExact Polyethersulfone (PES) Syringe Filters, 0.45 µm, 25 mm, 100/Pk - LE-IWT-ES10074

Syringe filters span a wide range of membrane chemistries and pore sizes, so the format can be matched to the sample matrix and solvent system in use. PES pairs fast flow with reduced protein and antibody adsorption while keeping particle retention absolute at its specified micron rating and handles strong bases across a broad aqueous range. Polyolefin construction sheds virtually no extractable material into the sample while providing a factory-sterilized fluid path suited to aseptic sample preparation and routes flow to minimize backpressure in service. Where small-volume samples must reach the instrument clean, low hold-up volume keeps sample loss minimal while the instrument stays protected from particulate damage.

Membrane Characteristics

• Chemical breadth spans alcohols, glycols, and aqueous buffers
• High flow rate pairs with a low extractable background
• Ionic extractables from the membrane stay very low
• Inherent hydrophilicity allows instant aqueous wetting with no pre-wetting step
• Compatibility spans both nucleic acid and protein-based filtration

Housing Characteristics

• Polypropylene housing tolerates dilute aqueous acids, bases, and alcohols used in routine sample prep
• Optimized internal geometry minimizes backpressure in service
• Each housing is factory-sterilized and sealed individually to maintain sterility through the supply chain
• Minimal ionic background from the polypropylene housing supports ion chromatography and trace-metal ICP-MS sample preparation

Particulates in your buffers, reagents, and aqueous samples slow your preparation and throw off its consistency. General-purpose aqueous filtration supports the sample types you handle every day across your water-analysis and general analytical workflows.
