Description
CHROMAFIL GF/PET-20/25 disposable filters are multi-layer syringe filters that combine a glass fibre prefilter with a polyester membrane for reliable sample clarification. Dual pore sizes of 1,0/0,2 µm and a 25 mm membrane diameter support efficient particulate retention ahead of chromatographic or spectroscopic work. A blue top and orange bottom colour code makes the filter type easy to recognise at the bench. This BIGbox presentation supplies 400 pieces in a PE screw jar, suited to busy analytical and quality-control laboratories that need a steady stock of consistent units. The glass fibre/polyester membrane stack from manufacturer Macherey-Nagel is intended for routine single-use filtration of liquid samples where a coarser prefilter protects the finer 0,2 µm layer. Compact 25 mm housings integrate smoothly into standard disposable filter workflows for solvents, buffers and aqueous preparations. Packaged for high-volume use, the BIGbox format reduces reorder frequency while keeping filters protected until needed.
This article is part of Syringe filters, in Filtration.

Questions about CHROMAFIL GF/PET-20/25, BIGbox
What is this article?
CHROMAFIL GF/PET-20/25, 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.
