Beschrijving
CHROMAFIL GF/PVDF-45/25 is a disposable syringe filter with a dual glass-fibre/polyvinylidene difluoride (GF/PVDF) membrane for sample clarification and particulate removal ahead of chromatographic or spectroscopic analysis. The multi-layer design combines a glass-fibre prefilter with a PVDF membrane at pore diameters of 1,0/0,45 µm and a membrane diameter of 25 mm, supporting efficient filtration of aqueous and selected organic sample matrices. Colour coding—black on the upper housing and white on the lower housing—helps distinguish the filter type quickly at the bench. Supplied in packs of 100 pieces from manufacturer Macherey-Nagel, these CHROMAFIL units are intended for routine laboratory sample preparation where a robust GF prefilter and a 0,45 µm PVDF finishing membrane are required. The 25 mm format suits moderate sample volumes typical of HPLC, UHPLC and general analytical workflows. Use as a syringe-tip filter for particle reduction and protection of sensitive instrumentation and columns.

Questions about CHROMAFIL GF/PVDF-45/25
What is this article?
CHROMAFIL GF/PVDF-45/25 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.
