Beschrijving
Chromatography columns 1000 ml are simple laboratory columns built for larger-scale chromatographic separations. Each unit offers a 1000 ml capacity with dimensions of 40 × 800 mm and a 2,5 mm bore. The column is equipped with an NS stopcock valve and PTFE spindle for precise flow regulation during packing, washing and elution. Available as one piece from manufacturer Witeg, these columns fit preparative and semi-preparative workflows in organic chemistry, natural-product isolation and biochemical purification. The extended 40 mm by 800 mm geometry provides ample bed volume for silica, polymer resins or affinity media under gravity or low-pressure conditions. PTFE spindle construction supports compatibility with a wide range of organic solvents and aqueous mobile phases. Visual observation of the stationary phase and solvent front is maintained throughout the separation. As chromatography accessories they integrate readily with standard laboratory stands, clamps and fraction collectors where controlled solvent delivery and robust valve performance are essential.
This article is part of Flash, empty & glass chromatography columns, in SPE & sample preparation.

Questions about CHROMATOGRAPHY COLUMNS, 1 000 ML, ST-ST
What is this article?
CHROMATOGRAPHY COLUMNS, 1 000 ML, ST-ST is the article on this page. Luminix Health distributes Witeg for laboratory use. It sits in Flash-, lege & glazen chromatografiekolommen, inside SPE & monstervoorbereiding, in Chromatografie.
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 & monstervoorbereiding. The sub-category is Flash-, lege & glazen chromatografiekolommen. The catalogue is Chromatografie.
Shelves beside this one are SPE-cartridges & kolommen and Sorbentia, silicagel & ionenwisselaars.
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.
