This is used for determining nitrogen, in organic compounds. Both the digestion and distillation stages can be performed in this apparatus. The assembly shown is the distillation stage where the amount of ammonia, and hence nitrogen is established. The inlet tube allows the permangnate solution to be introduced after distillation. Supplied with outer interchangeable 24/29 joint on the flask and an outer interchangeable 19/26 on the condenser.

This is a general purpose batch distillation assembly with the facility for addition via the inter - changeable stoppered neck. Ideally suited for the batch production of high purity distilled water. The flask has flat bottom with a side delivery tube connected to Friedrichs spiral condenser for increased distillation rates and interchangeable 24 / 29 joints between the condensor and side arm of the flask.
