5.3.2 Drying
The glass oven can also be used to dry solid substances.
Unlike permanently installed drying cabinets, the drying oven
only has to heat up a small volume. It requires less energy,
reaches the desired temperature more quickly, and thereby
reduces the time for drying. Moreover, if used as a vacuum
oven, it has a significantly tighter seal than a drying cabinet
and can therefore maintain a better vacuum. There are three
methods used for drying direct drying, indirect drying, and
rotary drying. The drying accessory is used for direct and
indirect drying, the rotary flask for rotary drying.
