Description
CHROMAFIL Xtra PES-45/25 is a disposable syringe filter for routine sample preparation and clarification in analytical laboratories. It combines a polyethersulfone (PES) membrane with a pore size of 0,45 µm and a membrane diameter of 25 mm inside a colourless, labelled polypropylene housing. The PES membrane is intended for aqueous and many polar media where fine particulate removal is required before chromatography, spectroscopy or other downstream measurements. Clear PP housing allows visual control of the filtration path, while the printed labelling supports fast identification at the bench and reduces mix-ups between pore sizes. Packaged as 100 pieces per pack, these single-use filters help limit cross-contamination between samples and simplify workflow organisation. CHROMAFIL Xtra PES-45/25 from manufacturer Macherey-Nagel belongs to the established syringe-filter range used for HPLC sample clean-up and general laboratory filtration. The 0,45 µm / 25 mm PES format is a practical choice whenever reproducible clarification of small liquid volumes is needed without additional hardware beyond a standard syringe.
This article is part of Syringe filters, in Filtration.

Questions about CHROMAFIL Xtra PES-45/25
What is this article?
CHROMAFIL Xtra PES-45/25 is the article on this page. Luminix Health distributes Macherey-Nagel for laboratory use. It sits in Syringe filters, inside Filtration, in Lab consumables.
A syringe filter is a membrane in a plastic housing on a Luer fitting. Pore size, membrane polymer and diameter are the three choices. 0.2 µm is the sterilising and the HPLC-particle cut. 0.45 µm is the coarser clarification. Aqueous and solvent-resistant membranes are different polymers.
Filtration holds back what is larger than the pores and lets the rest through. Paper is the ordinary laboratory filter. A membrane has a stated pore size and a polymer that must survive the solvent. A syringe filter is that membrane in a housing on a syringe. Glass fibre takes a higher dirt load. Ultrafiltration holds back macromolecules and passes salts. The pore size, the chemical compatibility and the volume are the three choices. Laboratory apparatus around filtration is indexed under ISO laboratory apparatus.
