Description
Chromatography column 190 ml is a glass laboratory column intended for liquid chromatographic separations, offering a working volume of 190 ml and column dimensions of 20 × 600 mm. The upper end carries an NS 29/32 socket for straightforward connection of solvent reservoirs or adapters, while the outlet is fitted with an NS-PTFE stopcock that incorporates a solid plug and threaded stopcock lock for secure, leak-resistant flow control. A fused-in frit of porosity P0 retains the stationary phase bed, and the stopcock bore of 2,5 mm permits fine regulation of eluent delivery during fractionation. This column from manufacturer Witeg is well suited to gravity-fed and flash chromatography workflows in research, natural-product isolation and teaching laboratories. With a net weight of 0,23 kg it mounts easily on standard stands and can be cleaned and re-packed between runs. The combination of defined geometry, reliable PTFE stopcock hardware and integrated frit support makes the format practical for medium-scale preparative work requiring reproducible packing and controlled elution.

Questions about Chromatographic-columns, w. ST-socket 2
What is this article?
Chromatographic-columns, w. ST-socket 2 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.
