PES Syringe Filter w/ Glass Fiber Prefilter, 0.22µm, 13mm, Nonsterile, Luer-Lok, 100/pk
LabExact SKU: LE-IWT-ES10206

LabExact Polyethersulfone (PES) Syringe Filters, 0.22 µm, 13 mm, 100/Pk - LE-IWT-ES10206

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. PES pairs fast flow with reduced protein and antibody adsorption while staying stable across the pH 1 to 14 range and loads aqueous buffers with zero pre-wetting delay. Low-extractable polypropylene keeps sample purity intact through the filtration pass and sustains efficient flow on viscous samples. 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
• Non-ionic surface avoids charge-driven protein binding of positively and negatively charged membrane types
• Compatibility spans both nucleic acid and protein-based filtration
• Absolute pore size rating holds consistent across every lot
• Aromatic sulfone backbone underlies stability across the full pH range

Housing Characteristics

• Rigid polypropylene body maintains its geometry through routine filtration pressure
• Plasticizer-free polyolefin construction keeps the fluid path clean
• Housing rated for reliable filtration under syringe-applied backpressure at its maximum operating pressure
• Inert polyolefin wall contributes minimal sample adsorption to the filtrate

A particulate-laden aqueous sample makes the rest of your preparation unpredictable. General-purpose aqueous filtration supports the sample types you handle every day across your water-analysis and general analytical workflows.
