Description
Chromatography column 280 ml is a glass chromatography column fitted with an NS 29/32 socket, a valve and PTFE spindle, threaded lock and a fused frit of porosity P0. The column body measures 30 x 400 mm, holds 280 ml and has a bore of 2,5 mm. These chromatography columns from manufacturer Witeg combine the larger NS 29/32 ground-joint socket with a valve assembly that includes a PTFE spindle and threaded stopcock security. The frit of porosity P0 is fused directly into the glass, retaining packing material during operation. Internal dimensions of 30 x 400 mm provide the 280 ml working volume, while the 2,5 mm bore supports controlled flow of mobile phase. Net weight is 0,17 kg. Supplied as a single piece, the column functions as chromatography accessory for laboratory separation work requiring NS 29/32 connections and a reliable PTFE-spindle valve.
This article is part of Flash, empty & glass chromatography columns, in SPE & sample preparation.

Questions about Chromatograpy-columns, ST-socket 29/32,
What is this article?
Chromatograpy-columns, ST-socket 29/32, 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.
