Description
Chromatography columns 35 ml are simple laboratory glass columns intended for routine separation work. Each unit measures 15 × 200 mm and is fitted with an NS stopcock that incorporates a valve and PTFE spindle, providing a bore of 2,5 mm for controlled solvent flow. The 35 ml working volume supports packing of common stationary phases used in analytical and small-scale preparative chromatography. PTFE components ensure broad chemical compatibility with aqueous buffers and organic mobile phases. These columns from manufacturer Witeg are well suited to gel filtration, ion-exchange or adsorption techniques performed on the laboratory bench. Compact dimensions allow multiple columns to be operated in parallel in teaching or research settings. The integrated valve enables operators to start, stop or fine-tune elution without extra fittings, while the robust glass construction withstands repeated use under standard laboratory conditions. Ideal for educational laboratories and quality-control environments requiring reliable, modest-volume chromatography hardware.
This article is part of Flash, empty & glass chromatography columns, in SPE & sample preparation.

Questions about Chromatographic-columns, 35 ml, ST-stop
What is this article?
Chromatographic-columns, 35 ml, ST-stop 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.
