Glass Liebig Condenser

Quick answer: A Liebig condenser is used in distillation to cool and condense vapour back into liquid, allowing the distillate to be collected as a purified or separated liquid fraction.
The condenser consists of an inner glass tube through which hot vapour passes, surrounded by an outer water jacket carrying a continuous flow of cooling water. As the vapour travels through the inner tube, it loses heat to the cooler water in the jacket and condenses back into liquid, which then drains out and is collected. This straightforward, effective cooling design has made the Liebig condenser one of the most familiar pieces of glassware in distillation setups.
For best cooling efficiency, water is normally run in at the lower end of the jacket, nearest the outlet, and out at the upper end, keeping the jacket filled with water and maximising cooling where the vapour first enters the condenser.

Frequently Asked Questions
What is a Liebig condenser used for?
It is used in distillation to cool and condense vapour back into liquid, allowing the distillate to be collected as it flows out of the condenser.
How does the Liebig condenser cool the vapour?
An outer water jacket carries a continuous flow of cooling water around the inner glass tube, so vapour passing through the inner tube loses heat to the surrounding water and condenses back to liquid.
Which direction should cooling water flow through the condenser?
Cooling water should normally flow in at the lower, outlet end of the vapour path and out at the upper end, so that the jacket stays filled with water and cooling is most effective where the vapour is hottest.
What kind of distillations use a Liebig condenser?
It is commonly used for simple distillation of liquids with a reasonably wide boiling point range in teaching and research laboratories.
Can the condenser be used with different glass joint sizes?
Liebig condensers are supplied with standard ground glass joints; confirm the exact joint size of this condenser matches the rest of your distillation setup before use.
Does LabEquip supply Liebig condensers for bulk or institutional orders?
Yes. LabEquip supplies glass Liebig condensers to schools, colleges and laboratories across India, including bulk and institutional orders. Contact us for a quotation.
