A Graham condenser is a key component for setting up a distillation apparatus. This borosilicate glass 300 mm condenser has a coiled inner tube to provide additional surface area for highly efficient cooling.

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

This Graham condenser is designed to be connected to other components using rubber stoppers. The upper (inlet) tube has an inside diameter of about 18 mm which fits a No. 3 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 Graham condenser to a standard faucet.

NOTE: Actual product may vary from the one pictured due to differences in suppliers.May come packaged with a saline solution to help prevent breakage in transit. Discard the solution before use.
