Description
CHROMAFIL Xtra PES-20/25 is a disposable syringe filter equipped with a polyethersulfone (PES) membrane, a pore size of 0,2 µm and a membrane diameter of 25 mm. It supports fine filtration and sample clarification prior to analytical measurement, helping remove particulates from aqueous laboratory samples. The membrane is mounted in a colourless polypropylene housing that is labelled for straightforward identification during multi-step preparation work. With a 25 mm membrane diameter, the format balances filtration area and handling convenience for typical syringe-based workflows. Supplied in packs of 100 pieces from manufacturer Macherey-Nagel, this CHROMAFIL Xtra PES filter is suited to routine laboratory filtration where polyethersulfone membranes are preferred for aqueous applications. Ready-to-use construction reduces preparation time at the bench and supports consistent sample handling in research, quality control and method development. Clear housing labelling assists organisation when several pore sizes or membrane chemistries are used side by side.

Questions about CHROMAFIL Xtra PES-20/25
What is this article?
CHROMAFIL Xtra PES-20/25 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.
