Description
CHROMABOND Flash DL 25 empty columns are Flash Direct Load cartridges intended for solid-sample application in flash chromatography. Each polypropylene cartridge offers a volume of 45 mL, suitable for approximately 25 g of silica gel or 15 g of diatomaceous earth, giving laboratories flexible packing options for preparative work. The set includes three PE filter elements per cartridge—one already inserted and two supplied separately—so beds can be retained securely during loading and elution. Connections follow a practical Luer-Lock layout with a female Luer-Lock inlet and a male Luer-Lock outlet for straightforward integration into standard flash systems. Offered as a pack of 50 pieces from manufacturer Macherey-Nagel, these empty DL 25 columns support custom solid-phase preparation, method development and routine Direct Load workflows. They are aimed at laboratories that need empty Flash Direct Load hardware rather than pre-packed media, while remaining fully aligned with the CHROMABOND Flash DL 25 format for consistent cartridge handling and sample introduction.
This article is part of SPE cartridges & columns, in SPE & sample preparation.

Questions about Chromab. Flash DL 25, empty columns
What is this article?
Chromab. Flash DL 25, empty columns 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.
