ABSTRACT:
Improved kugelrohr or apparatus for distilling or separating liquids. It includes a rugged, reliable air oven and drive unit with numerous safety features. One or more external guards eliminate burn hazard and risk of accidental contact. A thermal isolation support isolates the oven from its rest surface. A grounded heating element eliminates shock hazards. The oven is fitted with a grommet or bushing to support a flask connected to one or more additional flasks in a series. The outlet of the last flask in the series is connected to a drive tube via a flexible coupling. The drive tube is connected to a rotary bearing assembly mounted on a drive unit. The oven and the flasks may include impellers for circulating air to enhance heating efficiency.
