Description
CHROMAFIL Xtra PTFE-45/25 BIGbox is a bulk pack of disposable syringe filters intended for laboratories with elevated sample throughput. Each filter uses a polytetrafluoroethylene (PTFE) membrane with a pore size of 0,45 µm and a membrane diameter of 25 mm, housed in a colourless polypropylene (PP) body that is labelled for clear identification. The PTFE membrane supports sample clarification where this polymer chemistry is required for chemical compatibility ahead of instrumental analysis. The BIGbox format supplies 400 pieces in a PE screw-top container, reducing reorder frequency and keeping a large stock of identical filters ready at the bench. CHROMAFIL Xtra PTFE-45/25 from manufacturer Macherey-Nagel in this bulk presentation suits chemical, pharmaceutical, environmental and QC environments that process many samples daily. Labelled colourless housings help maintain orientation of pore size and membrane type during parallel filtrations. The combination of 0,45 µm PTFE, 25 mm diameter and a 400-piece PE screw jar offers a practical high-volume option within the CHROMAFIL Xtra syringe-filter range for routine particulate removal before chromatography or related techniques.
This article belongs on Syringe filters, in Filtration.

Questions about CHROMAFIL Xtra PTFE-45/25, BIGbox
What is this article?
CHROMAFIL Xtra PTFE-45/25, BIGbox 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.
