Description
CHROMABOND empty columns with a 45 mL volume are polypropylene (PP) solid-phase extraction accessories fitted with polyethylene (PE) filter elements for laboratory chromatography. Each column is supplied with one PE filter element already inserted and a second PE filter element enclosed separately, so users can pack custom sorbent beds to match method requirements. The 45 mL format suits sample-preparation workflows that need larger bed volumes, higher sample loads or multi-step clean-up. Offered in packs of 20 pieces from manufacturer Macherey-Nagel, these empty columns support method development and routine SPE work in which analysts prefer to select and fill their own stationary phases. The PP body with PE frits provides a practical platform for solid-phase extraction, enrichment and purification across analytical chemistry, food testing and environmental laboratories. Compatible with standard SPE manifolds and vacuum systems, the columns help configure tailored extraction protocols without relying only on pre-packed cartridges, giving chromatographers control over sorbent choice, bed height and elution strategy for diverse analyte classes.
This article is part of SPE cartridges & columns, in SPE & sample preparation.

Questions about Chromab. empty columns, 45 mL, PP
What is this article?
Chromab. empty columns, 45 mL, PP 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.
