Description
CHROMABOND Flash RS 4 SPHERE SiOH 25 µm columns are ready-to-use flash chromatography cartridges packed with spherical unmodified silica (SiOH) of 25 µm particle size. Each column contains 4 g of sorbent in a polypropylene body fitted with polyethylene filter elements, providing a robust format for normal-phase flash separations and sample clean-up. The spherical SiOH phase offers defined particle geometry for laboratory purification of organic intermediates, natural products, and synthetic mixtures under flash conditions. Columns are supplied non-sterile in packs of 20 pieces, suited to method development and preparative workflows that require consistent silica-based normal-phase media. Housing and frit materials (PP with PE filter elements) are chosen for chemical compatibility typical of organic flash solvents. These Flash RS 4 units from manufacturer Macherey-Nagel fit standard flash systems that accept the RS 4 format and support reproducible loading and elution in research and process-support laboratories. Use them wherever 25 µm spherical silica flash cartridges with a 4 g bed are specified for routine normal-phase purification.
This article is part of SPE cartridges & columns, in SPE & sample preparation.

Questions about Chromab. Flash RS 4 SPHERE SiOH 25 µm
What is this article?
Chromab. Flash RS 4 SPHERE SiOH 25 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.
