Description
Kuderna-Danish evaporator macro is a threaded laboratory glassware assembly designed for efficient solvent concentration and sample preparation. The complete set consists of a three-ball Snyder column, a 500 ml evaporator flask and a 15 ml receiver vessel, all fabricated from borosilicate glass 3.3 for excellent thermal and chemical resistance. This classic configuration supports gentle evaporative concentration of extracts under controlled conditions, commonly applied in environmental and analytical chemistry workflows. The threaded connections ensure secure assembly and straightforward handling during routine use. Offered by manufacturer Witeg, the macro version provides ample capacity for larger sample volumes while maintaining the precision expected of Kuderna-Danish apparatus. Borosilicate glass 3.3 construction withstands repeated heating and cooling cycles without compromising clarity or dimensional stability. Ideal for laboratories performing residue analysis or extract concentration prior to chromatographic determination, the unit arrives as a ready-to-use single piece set.

Questions about Kuderna-Danish concentrator , wit
What is this article?
Kuderna-Danish concentrator , wit is the article on this page. Luminix Health distributes Witeg for laboratory use. It sits in Rotary evaporators, inside Pumps, vacuum & evaporation, in Instruments de laboratoire.
A rotary evaporator spins a flask under vacuum so solvent boils off a sample at a modest temperature. The flask size, the condenser type and the vacuum the seal can hold are the specification. Bumping is a flask that was too full or a vacuum that arrived too fast.
A vacuum pump lowers the pressure above a liquid so it boils at a lower temperature. That is the point of a rotary evaporator: solvent leaves a sample without cooking it. A diaphragm pump or a rotary-vane pump is chosen by the vacuum it reaches and by whether solvent vapour will destroy it. A peristaltic pump moves liquid by squeezing a tube, so the liquid touches only the tube. A barrel pump transfers a larger volume from a drum. The glassware on the evaporator is indexed under ISO laboratory glassware. Solvent identity is on PubChem.
