Liebig condensers are a simple condenser design used to cool and condense hot vapor as part of a distilling apparatus. This 300 mm condenser has a straight inner tube that the condensing vapor passes through and a large outer jacket that cooling water passes through.

While a condenser can be used in a variety of distillation set-ups, we recommend using this with a Kjeldahl distillation bulb to improve distillation efficiency.

This Liebig condenser is designed to be connected to other components using rubber stoppers. The upper (inlet) tube has an inside diameter of about 17 mm which fits a No. 2 rubber stopper.

Use with a ring stand and clamp for support.

We also have a special condenser accessory kit with everything you need to connect this Liebig condenser to a standard faucet.

NOTE: Actual product may vary from the one pictured due to differences in suppliers.
