Description
Chromatography column 18 ml provides a slightly larger bed volume for laboratory separation procedures. It is equipped at the top with an NS 14/23 socket and at the bottom with an NS-PTFE stopcock that incorporates a solid plug and thread lock. A fused frit of porosity P0 is permanently sealed into the column body. Working dimensions are 15 × 100 mm, giving a nominal capacity of 18 ml and a bore diameter of 2,5 mm. Net and gross weight each measure 0,048 kg. Supplied as one piece, the column is intended for liquid-chromatography workflows that benefit from the stated geometry and PTFE sealing. The item is manufactured by Witeg and retains the exact joint, frit and stopcock configuration described by the producer. Dimensional, volume and weight data follow the manufacturer specification without added claims, making the column a straightforward choice for analytical or small-scale preparative chromatography in research settings.
This article is part of Flash, empty & glass chromatography columns, in SPE & sample preparation.

Questions about Chromatograpy-columns, with ST-socket 1
What is this article?
Chromatograpy-columns, with ST-socket 1 is the article on this page. Luminix Health distributes Witeg for laboratory use. It sits in Flash, empty & glass chromatography columns, inside SPE & sample preparation, in Chromatography equipment.
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 & sample preparation. The sub-category is Flash, empty & glass chromatography columns. The catalogue is Chromatography equipment.
Shelves beside this one are SPE cartridges & columns and Sorbents, silica gel & ion exchangers.
