Beschrijving
Chromatography column 8 ml is a laboratory glass column for liquid chromatography applications, offering a working volume of 8 ml and body dimensions of 10 x 100 mm. The upper end carries an NS 14/23 ground joint sleeve that accepts standard reservoirs, adapters or funnels for convenient sample and solvent introduction. Flow is regulated by an integrated valve fitted with a PTFE spindle and thread lock, providing chemical resistance and secure shut-off during packing, equilibration and elution steps. The internal bore measures 2,5 mm, supporting controlled solvent delivery through the packed bed. Supplied as a single piece from manufacturer Witeg, the column is intended as chromatography accessory glassware for analytical and preparative work in research, teaching and quality-control laboratories. Its compact format suits small-scale separations, method development and educational demonstrations where reliable joint connections and inert flow control are required. The combination of NS joint, PTFE spindle and defined geometry allows straightforward integration into existing laboratory setups without additional custom fittings.
This article is part of Flash, empty & glass chromatography columns, in SPE & sample preparation.

Questions about CHROMATOGRAPY-COLUMNS, ST-SOCKET 14/23,
What is this article?
CHROMATOGRAPY-COLUMNS, ST-SOCKET 14/23, is the article on this page. Luminix Health distributes Witeg for laboratory use. It sits in Flash-, lege & glazen chromatografiekolommen, inside SPE & monstervoorbereiding, in Chromatografie.
A flash column or an empty glass column is the tube a separation is packed or run in, under gravity or under air pressure. Diameter and length, and whether it arrives prepacked, are the choices. An empty column still needs a frit and a sorbent.
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 & monstervoorbereiding. The sub-category is Flash-, lege & glazen chromatografiekolommen. The catalogue is Chromatografie.
