Description
Chromatography column 35 ml is a laboratory column intended for chromatographic separation and fractionation tasks. It incorporates a top NS socket 14/23, an NS-PTFE stopcock with solid plug and threaded stopcock lock, and a fused frit of porosity P0. The column measures 15 x 200 mm with a bore of 2,5 mm and offers a working volume of 35 ml. Supplied as one piece with a net weight of 0,06 kg, the unit is produced by manufacturer Witeg. The design enables secure flow control, effective packing retention and straightforward integration into standard ground-joint systems. PTFE construction of the stopcock provides broad chemical resistance during solvent elution, while the threaded lock minimises the risk of accidental opening. This 35 ml format suits medium-scale analytical work, method optimisation and preparative separations in research or quality-control laboratories. Defined dimensions and bore diameter support reproducible flow rates when packing stationary phases for organic or biochemical applications.

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.
What should I check before I order?
