Description
CHROMAFIL Xtra PVDF-20/25 is a disposable syringe filter for sample clarification and particulate removal ahead of analytical work. It uses a polyvinylidene fluoride (PVDF) membrane with a pore size of 0,2 µm and a membrane diameter of 25 mm, mounted in a colourless polypropylene (PP) housing that is labelled for clear identification at the bench. The 0,2 µm rating supports fine filtration of aqueous and many organic sample matrices prior to HPLC, GC or other instrumental methods, while the 25 mm format offers a practical filtration area for typical syringe volumes. Packaged as 100 pieces, the unit suits routine laboratory throughput where consistent membrane performance and easy handling matter. This CHROMAFIL Xtra filter from manufacturer Macherey-Nagel combines a labelled PP casing with a defined PVDF membrane geometry for reproducible sample preparation. Colourless housing aids visual checks during use, and the printed marking helps avoid mix-ups when several pore sizes are stocked side by side. The product belongs to the CHROMAFIL Xtra range of syringe filters intended for everyday laboratory filtration tasks requiring a 0,2 µm PVDF membrane in the 25 mm diameter class.
This article is part of Syringe filters, in Filtration.

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