Description
Designed for sterile filtration, low-protein-binding recovery, and reliable laboratory workflows, these sterile PES syringe filters combine high flow performance with excellent biological compatibility for aqueous solution preparation, sample clarification, and sterile processing applications.
Featuring a hydrophilic PES membrane with 0.22 μm pore size, the filters provide efficient microorganism removal while maintaining >98.5% protein recovery and extremely low protein binding (<1.5%). The female luer lock inlet and male luer slip outlet support secure syringe integration and smooth downstream dispensing during routine laboratory workflows.
Pre-sterilized and individually packed, these syringe filters are manufactured for contamination-sensitive applications requiring low extractables, non-pyrogenic performance, and surfactant-free filtration. Multiple membrane diameters allow laboratories to optimize throughput, filtration speed, and sample volume compatibility across research, analytical, and bioprocess workflows.

FAQ
What is a 0.22 μm sterile PES syringe filter used for?
A 0.22 μm sterile PES syringe filter is commonly used for sterile filtration and clarification of aqueous solutions, cell culture media, buffers, protein solutions, and biological samples. The 0.22 μm pore size helps remove microorganisms and fine particles before downstream laboratory use.
Why choose a PES syringe filter for protein solutions?
PES, or polyethersulfone, is widely selected for protein solution filtration because it provides low protein binding, high flow performance, and good compatibility with aqueous biological samples. This helps reduce sample loss during filtration of proteins, enzymes, antibodies, and other valuable biomolecules.
Is this syringe filter suitable for cell culture media filtration?
Yes. The hydrophilic PES membrane is suitable for sterile filtration of cell culture media, tissue culture additives, supplements, and aqueous buffers. Its low extractables and low protein binding properties help maintain filtrate quality in contamination-sensitive cell culture workflows.
What is the difference between PES, PVDF, nylon, and PTFE syringe filters?
PES syringe filters are generally preferred for aqueous biological solutions, cell culture media, and protein-containing samples because they offer low protein binding and fast flow. PVDF is also used for low-binding filtration, nylon is often used for general aqueous or mild organic sample preparation, and PTFE is typically selected for organic solvent filtration.
How do I choose between 13 mm, 25 mm, 30 mm, and 33 mm PES syringe filters?
Smaller 13 mm PES syringe filters are suitable for low-volume or precious samples where minimal hold-up is important. Larger 25 mm, 30 mm, and 33 mm filters provide greater filtration area, higher throughput, and faster flow, making them better suited for larger sample volumes or solutions with higher particulate load.
Can this sterile syringe filter be used for buffer and reagent preparation?
Yes. These sterile PES syringe filters are suitable for filtering laboratory buffers, aqueous reagents, molecular biology solutions, and research-grade media components. The hydrophilic PES membrane supports smooth filtration of water-based solutions without requiring pre-wetting for routine aqueous workflows.
Does a 0.22 μm PES syringe filter remove endotoxins or viruses?
No. A 0.22 μm PES syringe filter is designed for sterile filtration, clarification, and particle removal from aqueous solutions. It should not be used as an endotoxin removal device or as a validated virus removal filter unless specifically tested and labeled for those applications.
What connector type does this PES syringe filter use?
These sterile PES syringe filters use a female luer lock inlet and male luer slip outlet. This configuration supports secure syringe attachment and convenient dispensing during sterile filtration, sample clarification, and routine laboratory sample preparation.
