Beschrijving
CHROMAFIL Xtra PA-45/25 is a disposable syringe filter for laboratory sample preparation and particulate removal. It features a polyamide (nylon) membrane with a pore size of 0,45 µm and a membrane diameter of 25 mm, appropriate for clarifying aqueous and many organic samples prior to chromatography or related analytical techniques. The membrane sits in a colourless polypropylene housing that is labelled for easy recognition during routine bench work. This BIGbox version provides 400 pieces in a PE screw jar, ideal for laboratories with continuous filtration demand and a need for bulk single-use stock. Filters in the CHROMAFIL Xtra line from manufacturer Macherey-Nagel are widely applied for HPLC sample clean-up, solvent filtration and general clarification tasks. The polyamide membrane delivers practical chemical resistance toward common laboratory solvents, and the 25 mm format balances filtration area with convenient handling. Each filter is intended for one-time use to help maintain sample integrity and minimise cross-contamination across sequential preparations in analytical and quality-control settings.
This article belongs on Syringe filters, in Filtration.

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