Introduction
Your general purpose heating and/or stirring
devices are intended for general laboratory pro-
cedures. A vessel with a flat bottom is recom-
mended on the hot plate and stirring hot plate for
ideal heat transfer. Avoid metal containers, sand-
baths or vessels with a rim around the bottom as
these could cause damage to the hot plate and
stirring hot plate.
Both the temperature and speed controls are
combination on/off switches and setting selec-
tors.
