Description
CHROMABOND SiOH columns, 3 mL, 500 mg, glass are solid-phase extraction columns based on unmodified silica (SiOH) for laboratory sample preparation and chromatographic clean-up. Each unit combines a 3 mL column volume with a 500 mg sorbent fill, providing a defined polar silica bed for normal-phase SPE and related applications where analyte–silanol interactions are desired. The column body is glass and incorporates a glass-fibre filter element to hold the sorbent during solvent conditioning, sample loading, wash and elution sequences. Offered by manufacturer Macherey-Nagel in packs of 50 pieces, this glass format is intended for workflows that prefer a glass housing over plastic for solvent compatibility or laboratory preference. The columns integrate with common SPE manifolds and vacuum or pressure-assisted processing systems used across environmental, food, pharmaceutical and research laboratories. SiOH phases remain a standard choice when polar retention on bare silica supports matrix reduction or analyte enrichment ahead of HPLC, GC or other analytical techniques.
This article is part of SPE cartridges & columns, in SPE & sample preparation.

Questions about Chromab. columns SiOH, 3 mL, 500 mg, gl.
What is this article?
Chromab. columns SiOH, 3 mL, 500 mg, gl. 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.
