Description
CHROMABOND Flash RS 40 SiOH columns are ready-to-use flash chromatography columns packed with unmodified silica (SiOH) of 15–40 µm particle size. Each unit holds a 40 g sorbent bed and is built from polypropylene with polyethylene filter elements, giving a robust format for normal-phase flash and preparative separations. The SiOH phase is routinely applied to purify organic compounds, natural-product extracts and synthetic intermediates under standard flash conditions. Particle sizes in the 15–40 µm range offer a practical balance between separation efficiency and system back-pressure for many laboratory workflows. Columns are supplied in packs of 15 pieces from manufacturer Macherey-Nagel, supporting consistent packing quality without self-packing steps. The polypropylene body and PE filter elements are suited to typical organic mobile phases used in flash chromatography. These CHROMABOND Flash RS 40 SiOH columns help laboratories streamline clean-up, fractionation and method transfer in research and process-development settings where reproducible silica-based separations are required.
This article is part of SPE cartridges & columns, in SPE & sample preparation.

Questions about Chromab. Flash RS 40 SiOH, 15-40 µm
What is this article?
Chromab. Flash RS 40 SiOH, 15-40 µm is the article on this page. Luminix Health distributes Macherey-Nagel for laboratory use. It sits in SPE cartridges & columns, inside SPE & sample preparation, in Chromatography equipment.
An SPE cartridge holds a bed of sorbent. Bed mass, sorbent chemistry and volume are the specification. A 100 mg C18 cartridge and a 1 g C18 cartridge take different sample loads and different elution volumes. The method names all three.
Solid-phase extraction holds a compound on a sorbent while the rest of the sample is washed away, then releases it in a small volume. The sorbent, the bed mass and the solvents are the method. Silica, ion exchangers and polymer phases do different jobs. A flash column is the same idea scaled toward purification rather than trace cleanup. The molecules are on PubChem, named by IUPAC.
Which category should I open next?
The category is SPE & sample preparation. The sub-category is SPE cartridges & columns. The catalogue is Chromatography equipment.
Shelves beside this one are Sorbents, silica gel & ion exchangers and Flash, empty & glass chromatography columns.
