Description
CHROMAFIL PTFE-20/15 MS is a disposable syringe filter with a polytetrafluoroethylene (PTFE) membrane, a pore size of 0,2 µm and a membrane diameter of 15 mm. It is intended for sample clarification and particulate removal ahead of chromatographic or spectroscopic analysis, especially where aggressive organic solvents or mixed aqueous–organic matrices are handled. The housing is colour-coded yellow on the upper part and colourless on the lower part for rapid bench identification. Formerly known as CHROMAFIL O-20/15 MS, this BIGbox presentation from manufacturer Macherey-Nagel contains 800 pieces supplied in a PE screw-top container, supporting high-throughput laboratories that need a reliable bulk stock of ready-to-use filters. PTFE offers broad chemical resistance and low extractables, making the units suitable for filtration of solvents, reagents and sample solutions in routine analytical workflows. The compact 15 mm format helps limit hold-up volume while still providing practical filtration area for typical laboratory sample volumes. Consistent membrane quality and convenient bulk packaging help streamline sample-preparation steps without frequent reordering.
This article is part of Syringe filters, in Filtration.

Questions about CHROMAFIL PTFE-20/15 MS, BIGbox
What is this article?
CHROMAFIL PTFE-20/15 MS, 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.
