Description
CHROMAFIL Xtra GF/PA-45/25 is a disposable laboratory filter combining a glass fibre and polyamide membrane. It provides pore diameters of 1,0 µm and 0,45 µm with a membrane diameter of 25 mm, so coarser debris can be retained upstream of the finer polyamide layer. The assembly sits in a colourless polypropylene housing that is labelled for rapid identification at the bench. Packs contain 100 pieces and come from manufacturer Macherey-Nagel for everyday sample preparation in analytical laboratories. Glass fibre contributes particle-holding capacity, while polyamide is appropriate for many aqueous and polar organic samples encountered in chromatographic work. The 25 mm format offers a practical filtration area for typical syringe-driven volumes without excess hold-up. Clear labelling on the PP housing supports organised handling when several filter grades are in use. CHROMAFIL Xtra GF/PA-45/25 is designed for single-use filtration of laboratory solutions, buffers and samples ahead of instrumental analysis, keeping clean-up steps simple and reproducible.
This article is part of Syringe filters, in Filtration.

Questions about CHROMAFIL Xtra GF/PA-45/25
What is this article?
CHROMAFIL Xtra GF/PA-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.
