Description
CHROMAFIL Xtra GF/PA-20/25 is a disposable laboratory filter with a combined glass fibre and polyamide membrane. Pore diameters are 1,0 µm and 0,2 µm on a 25 mm membrane, giving a dual-layer format that pairs coarse prefiltration with finer retention in one unit. The membrane is mounted in a colourless polypropylene housing that is labelled for clear bench identification. Supplied in packs of 100 pieces from manufacturer Macherey-Nagel, these filters support routine sample preparation in analytical and chromatography workflows. The glass fibre layer offers high particle-holding capacity, while the polyamide membrane is suited to aqueous and polar organic media commonly handled in HPLC and related methods. The 25 mm diameter balances filtration area with practical flow for standard syringe volumes. Labelled PP housings simplify selection and traceability during multi-sample sequences. CHROMAFIL Xtra GF/PA-20/25 is intended for single-use filtration of laboratory solutions, buffers and samples prior to instrumental analysis, helping laboratories keep clean-up steps straightforward and consistent.
This article is part of Syringe filters, in Filtration.

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