Description
CHROMABOND Flash RS 25 SiOH is a pre-packed flash chromatography column filled with 25 g of SiOH sorbent for laboratory purification and preparative separation work. The column is built from polypropylene and equipped with polyethylene filter elements that retain the silica packing during solvent flow. As part of the Flash RS range, it presents unmodified silica (SiOH) in a ready-to-use cartridge format suited to normal-phase flash applications where a larger bed mass is advantageous. The 25 g fill supports higher sample loadings than smaller RS formats while remaining convenient for standard flash instrumentation and manual setups. Polypropylene construction provides a robust yet lightweight housing for everyday laboratory handling, and the PE filter elements help maintain bed integrity under typical operating conditions. These columns come from manufacturer Macherey-Nagel in packs of 15 pieces, aligning with batch-oriented purification schedules. Within the CHROMABOND Flash RS SiOH family they offer a defined 25 g silica bed and consistent cartridge geometry, making them a practical choice when reproducible packing and a ready-packed SiOH phase are required for flash chromatography accessories.
This article is part of SPE cartridges & columns, in SPE & sample preparation.

Questions about Chromab. Flash RS 25 SiOH
What is this article?
Chromab. Flash RS 25 SiOH 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.
