Description
Chromatography column 280 ml with 500 ml reservoir is a glass laboratory column designed for chromatographic separations and preparative fraction work. The column body measures 30 × 400 mm and offers a working volume of 280 ml, complemented by an integrated upper reservoir of 500 ml. It incorporates an NS 29/32 socket, a stopcock valve with PTFE spindle and a bore of 2,5 mm for reliable flow control. Supplied as one piece with a net weight of 0,36 kg, the column from manufacturer Witeg is appropriate for gravity or low-pressure chromatography in research, quality-control and teaching environments. The PTFE spindle provides smooth valve action and broad solvent compatibility. The generous reservoir facilitates convenient sample introduction and continuous solvent supply, while the lower valve enables accurate regulation during packing, washing and elution. The NS 29/32 joint ensures straightforward mounting on standard laboratory supports and connection to common adapters, making the column a practical accessory for silica-gel or other stationary-phase separations in organic and natural-product chemistry.

Questions about Chromatographic-columns w. reservoir 500
What is this article?
Chromatographic-columns w. reservoir 500 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.
