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.
