Description
CHROMAFIL GF/PVDF-45/25 BIGbox is a bulk pack of disposable syringe filters featuring a glass-fibre/polyvinylidene difluoride (GF/PVDF) dual membrane for laboratory sample preparation. Pore diameters of 1,0/0,45 µm and a 25 mm membrane diameter combine a glass-fibre prefilter layer with a PVDF membrane to reduce particulates before instrumental analysis. The housing is colour-coded black on top and white underneath for rapid visual identification. This BIGbox presentation from manufacturer Macherey-Nagel contains 400 pieces in a PE screw jar, suited to higher-throughput laboratories that need a consistent GF/PVDF 0,45 µm finishing filter without frequent reordering. The 25 mm CHROMAFIL format supports typical syringe-filter volumes used in HPLC sample clean-up and general clarification of aqueous and compatible organic solutions. Ideal where a dual-layer GF/PVDF membrane and economical bulk packaging are preferred for routine filtration tasks.
This article is part of Syringe filters, in Filtration.

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