Description
Chromatography column 70 ml is a glass chromatography column equipped with an NS 14/23 socket, a valve and PTFE spindle, threaded lock and a fused frit of porosity P0. The column measures 15 x 400 mm, provides a volume of 70 ml and features a bore of 2,5 mm. Chromatography columns from manufacturer Witeg incorporate the NS 14/23 ground-joint socket together with a valve that employs a PTFE spindle and threaded security for the stopcock. An eingeschmolzene frit of grade P0 is fused into the glass wall to hold the stationary phase. The slender 15 x 400 mm geometry yields the stated 70 ml capacity while the 2,5 mm bore allows regulated solvent delivery. Net weight is 0,124 kg. Delivered as one piece, the column serves as chromatography accessory for laboratory packing and elution procedures that utilise standard NS 14/23 joints and a PTFE-spindle valve assembly.
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, 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.
