Description
Chromatography column 70 ml is a glass laboratory column designed for preparative and analytical separation work. It features an upper ground joint sleeve NS 14/23, an NS-PTFE stopcock with PTFE plug and threaded stopcock lock, plus a fused frit of porosity P0. The working dimensions are 15 x 400 mm with a bore of 2,5 mm, giving a nominal volume of 70 ml. These construction details support reliable packing of stationary phases and controlled elution in routine chromatography applications. Supplied as a single piece from manufacturer Witeg, the column is suitable for gravity-flow or low-pressure setups commonly used in organic synthesis, natural-product isolation and educational laboratories. The integrated frit retains packing material while the PTFE stopcock allows fine flow adjustment without metal contact. Net weight is 0,132 kg. The robust glass body and standardised joints ensure compatibility with standard laboratory glassware, making the column a practical accessory for chromatography workflows that require defined bed volumes and reproducible solvent delivery.

Questions about Chromatographic-column 70 ml
What is this article?
Chromatographic-column 70 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?
