Description
CHROMAFIL Xtra H-PTFE-45/13 is a disposable syringe filter equipped with a hydrophilized polytetrafluoroethylene membrane, a pore size of 0,45 µm and a membrane diameter of 13 mm. It is designed for efficient sample clarification and particle removal prior to HPLC and related analytical techniques. Hydrophilized PTFE combines wide solvent compatibility with improved wetting for aqueous and mixed mobile phases. The filter body is colourless polypropylene and is labelled for straightforward identification during routine work. Inlet geometry is Luer-Lock and the outlet is standard Luer, ensuring reliable coupling to syringes and receiving vessels. Packaged as 100 pieces from manufacturer Macherey-Nagel, the 13 mm membrane diameter suits smaller sample volumes while the 0,45 µm pores provide effective retention of coarser particulates. Colourless housing allows visual control of the filtration process. These single-use devices support consistent laboratory sample preparation without the need for membrane handling or assembly.
This article is part of Syringe filters, in Filtration.

Questions about CHROMAFIL Xtra H-PTFE-45/13
What is this article?
CHROMAFIL Xtra H-PTFE-45/13 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.
