Description
Chromatography column 280 ml is a glass laboratory column built for larger-scale preparative separations and purification procedures. It incorporates an upper ground joint sleeve NS 29/32, an NS-PTFE stopcock with solid plug and threaded stopcock lock, together with a fused frit of porosity P0. The column measures 30 x 400 mm with a bore of 2,5 mm and offers a nominal volume of 280 ml. These specifications support efficient packing of stationary phases and controlled elution under gravity or low-pressure conditions. Available as a single piece from manufacturer Witeg, the column is appropriate for organic synthesis, natural-product isolation and laboratory environments that require higher bed volumes. The solid PTFE plug and thread lock provide reliable flow regulation, while the fused frit retains packing material securely. Net weight is 0,18 kg. Standard ground joints ensure compatibility with conventional laboratory glassware, allowing straightforward connection to reservoirs, adapters and collection vessels in chromatography workflows.

Questions about Chromatographic column 280 ml
What is this article?
Chromatographic column 280 ml 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?
