PES Syringe Filter, Hydrophilic, 0.22µm, 25mm, Luer-Lok, Nonsterile, 100/Pk
LabExact SKU: LE-IWT-ES10066

LabExact Polyethersulfone (PES) Syringe Filters, 0.22 µm, 25 mm, 100/Pk - LE-IWT-ES10066

A sterilizing-grade syringe filter delivers point-of-use sterile filtration in a single-use format, without the housing and gasket maintenance a reusable stainless steel filter holder requires. PES's open pore layout leaves proteins less surface to contact and reaches sterile-grade performance while protecting analyte yield. Thermal-bonded PP construction leaves no seam for sample to bypass the membrane and delivers a chemically clean filtrate to the downstream step. For workflows requiring validated sterile-grade performance, point-of-use retention meets it without a separate sterilization step.

Membrane Characteristics

• Chemical breadth spans alcohols, glycols, and aqueous buffers
• Antibody and protein samples pass through PES with minimal adsorptive loss
• Pore structure integrity holds through autoclave cycles up to 126°C
• Mechanical strength keeps the matrix intact under vacuum or pressure
• Aromatic sulfone backbone underlies stability across the full pH range

Housing Characteristics

• Minimal ionic background from the polypropylene housing supports ion chromatography and trace-metal ICP-MS sample preparation
• The seal formed against the membrane blocks bypass at rated operating pressure
• Resists stress cracking from aqueous salt and buffer solutions
• Burst pressure rating provides a wide safety margin above the rated maximum operating pressure

A particulate-laden aqueous sample makes the rest of your preparation unpredictable. General-purpose aqueous filtration supports the sample types you handle every day from reagent and buffer preparation through routine sample clarification.

Sterilization Guidance

Standard autoclave cycles at 121°C for 30 minutes prepare the device for sterile workflows.
