Liebig Condensers

The liebig condenser is the most basic water-cooled condenser,also named “water conendenser”,which consists of an inner straight tube surrounded by an outer jacket tube,the cool water flows through the outer jacket to condensate the vapor in the inner tube.Water can asborb much more heat than the same volume of air,and its constant circulation through the water jacket keeps the condenser’s temperature constant,Therefore,a liebig condenser has a better cooling performance than an air condenser.
A liebig condenser can be both used in a reflux and a distillation apparatus.In the reflux apparatus, the lower inner joint will be inserted into a round bottom flask which contains the mixture liquid,the upper outer joint may attach a dry tube to prevent atmospheric moisture from entering a reaction system.In the distillation apparatus,the liebig condenser is placed obliquely between a distillation flask and a receiving flask, a three way thermometer adapter and a take off adpater are used to connect them.
It is designed with standard taper joints at both ends, and two glass hose connections or removable hose connections as the inlet and outlet of the coolant liquid.
Made of high quality borosilicate glass 3.3 having very low?coefficients of thermal expansion for resistance to heat, and a very high resistance to chemical attack.Annealed at 800 degree Celsius ,can be heated directly in an open flame and can withstand typical laboratory thermal variations in Chemistry processes like heating and cooling.
