For example, a round bottom flask, Liebig condenser, and oil bubbler with ground glass joints may be rapidly fitted together to reflux a reaction mixture. This is a large improvement compared with older methods of custom-made glassware, which was time-consuming and expensive, or the use of less chemical resistant and heat resistant corks or ...
The earliest laboratory condenser, a "Gegenstromkühler" (counter-flow condenser), was invented in 1771 by the Swedish-German chemist Christian Weigel. [2]By the mid-19th century, German chemist Justus von Liebig would provide his own improvements on the preceding designs of Weigel and Johann Friedrich August Göttling, with the device becoming known as the Liebig condenser.
In a pot still, if the tube leading from the boiler to the condenser, the lyne arm, is angled upward, more liquid will have a chance to condense and flow back into the boiler leading to increased reflux. Typical results can increase production as high as 50% over the basic worm type condenser.
A kaliapparat. A kaliapparat is a laboratory device invented in 1831 by Justus von Liebig (1803–1873) for the analysis of carbon in organic compounds. [1] The device, made of glass, consists of a series of five bulbs connected and arranged in a triangular shape.
