Beschrijving
Kuderna-Danish evaporator micro is a compact borosilicate glass 3.3 assembly for controlled solvent concentration in analytical sample preparation. The threaded set consists of a three-ball Snyder column, a 40 ml evaporator and a 2 ml receiving vessel, enabling gentle distillation and recovery of small sample volumes with minimal hold-up. This micro-scale configuration is well suited to residue analysis, environmental extracts and other workflows where analytes must be concentrated prior to chromatographic determination. The Snyder column promotes efficient vapour–liquid contact during evaporation, supporting reproducible recovery while the 2 ml receiver collects the concentrated fraction ready for further work-up. Supplied as a complete glassware unit from manufacturer Witeg, the apparatus has a net weight of 0,17 kg and is straightforward to mount and handle on the laboratory bench. Chemically resistant borosilicate glass 3.3 withstands typical organic solvents used in concentration steps. Laboratories in food, environmental and pharmaceutical analysis benefit from a ready-to-use Kuderna-Danish micro evaporator that combines a three-ball column, 40 ml evaporator body and 2 ml receiver in one threaded system for routine micro-scale concentration.

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 Instrumenten.
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.
