Description
CHROMAFIL GF/RC-20/25 is a disposable syringe filter for sample preparation in analytical and research laboratories. It combines a glass fibre prefilter with a regenerated cellulose membrane, giving pore diameters of 1,0 µm and 0,2 µm on a 25 mm membrane. The dual-layer design retains coarser particles on the glass fibre layer while the regenerated cellulose membrane delivers fine clarification of aqueous and many polar organic solutions ahead of HPLC, UHPLC or other instrumental work. Top and bottom housings are both colour-coded blue for fast visual selection at the bench. Each pack contains 100 filters, supporting steady laboratory throughput. These CHROMAFIL units from manufacturer Macherey-Nagel fit standard Luer connections used with disposable syringes and offer a practical balance of filtration area and hold-up volume in the 25 mm format. Consistent membrane geometry and clear colour coding help laboratories keep sample clean-up reproducible and reduce the chance of selecting the wrong pore size during high-throughput workflows.

Questions about CHROMAFIL GF/RC-20/25
What is this article?
CHROMAFIL GF/RC-20/25 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.
