5.4.2 Kugelrohr / Distillation

The glass oven can be used for two types of distillation: single

distillation and fractional distillation. The fractional distillation

is a bulb to bulb distillation that uses three of four bulbs and

bulb cooling. The single distillation may be done either as a

bulb to bulb distillation using two bulbs and bulb cooling, or

with a condenser with a cooling coil and a collection ﬂask,

In this latter application, the glass oven may be viewed as a

small rotary evaporator. Common to all three types of distil-

lation is the fact that they all work using the bulb-tube drive.

Bulb to bulb distillation uses a tube that consists of as many

bulbs as there are components in the mixture.
