Description
Chromatography column 50 ml is a glass column designed for liquid chromatography separations in the laboratory. The upper end carries an NS socket 14/23 and an NS-PTFE stopcock equipped with a solid plug and threaded stopcock security. A fused frit of porosity P0 is sealed into the column. Measuring 15 × 300 mm, the column offers a capacity of 50 ml and a bore of 2,5 mm for regulated flow during elution. These construction details enable packing of standard stationary phases and support consistent fractionation of complex samples. Supplied by manufacturer Witeg, the column is suitable for research, educational and quality-control environments that require robust chromatography accessories. The PTFE stopcock components provide good chemical resistance, and the ground joint allows straightforward coupling to other glassware. Net weight is 0,098 kg, keeping the unit convenient for everyday bench use. It is well matched to method development, purification steps and preparative work where reliable glass columns are essential.

Questions about Chromatographic-columns, with ST-socket
What is this article?
Chromatographic-columns, with ST-socket 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.
What should I check before I order?
When this page shows a safety data sheet, use that manufacturer file. Hazard text does not belong in the sales description. For a pack size, a grade or a certificate that is not on the page, send a quote request or contact the team.
