Description
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 Flasks (other), inside Beakers & flasks, in Labware.
These are the flasks that are not a plain beaker, Erlenmeyer, round bottom or flat bottom: odd shapes, special necks, flasks defined by a use. The volume and the joint, if there is one, still have to match the setup.
A beaker is an open working vessel: easy to pour, poor as a measure. An Erlenmeyer flask has a flat base and a conical wall so a liquid can be swirled without climbing out. A round-bottom flask is for heating under a condenser, because the heat meets a curved wall and the joint at the neck connects to the rest of the glassware. Borosilicate is the glass that survives the temperature change. These forms are listed under ISO laboratory glassware.
Which category should I open next?
