Abstract

A glass distilling apparatus for water is described. It consists of a Pyrex flask attached to a condenser of the same material in such a way that the water level is maintained during operation. The heater is a 600 watt element made of nickel-chromium wire and directly immersed in the water. The capacity is about 700 cc per hour. The operation is automatic and the efficiency is about 85 per cent.
