What is liebeg condenser?

The Liebig condenser, also known as the water-cooled condenser, is a type of condenser used in laboratory experiments for cooling hot vapours. It is named after the German chemist Justus von Liebig, who invented it in 1835. It consists of a straight glass tube surrounded by a larger glass or plastic jacket through which cold water flows to cool the incoming vapor. The vapor enters the condenser through one end and is cooled as it passes through the condenser, eventually exiting through the other end as a liquid. The Liebig condenser is used in a variety of laboratory applications, including distillation, refluxing, and the synthesis of organic compounds. It is a simple and effective tool for cooling high-temperature vapors quickly, allowing for extraction of solvents and separation of chemical compounds.
