Description
Chromatography column 90 ml is a glass laboratory column intended for liquid chromatography and preparative separations. It features an upper NS socket 29/32 together with an NS-PTFE stopcock secured by a threaded lock. A fused frit of porosity P0 is permanently incorporated in the column body. The column measures 20 × 300 mm, holds 90 ml and has a stopcock bore of 2,5 mm, permitting controlled solvent flow. These attributes facilitate packing with conventional stationary phases and support reproducible isolation of target compounds. The column from manufacturer Witeg serves as a practical chromatography accessory for research, teaching and routine analytical laboratories. PTFE components contribute to chemical compatibility across many solvents, while the larger NS joint enables secure connection to complementary glassware. With a net weight of 0,135 kg the unit remains manageable on the laboratory bench. It is appropriate for sample clean-up, method development and small-scale preparative work requiring dependable glass chromatography hardware.

Questions about Chromatography column 90 ml
What is this article?
Chromatography column 90 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?
