Introduction
The Type 18300 hot plates are general purpose
heating devices intended for laboratory procedures
requiring temperatures from 38
°
C (100
°
F) to 371
°
C
(700
°
F). These hot plates are not to be used in the
presence of explosive vapors; this device contains
components which may ignite such materials. The
unit consists of (1) a heated plate, and (2) an
adjustable temperature control.
Principles of operation
The heating surface is comprised of glass bonded
to a steel plate, the glass providing excellent
corrosion resistance, the metal aiding in uniform
heat distribution. The heating plate temperature is
controlled by a bimetallic thermostat. The plate and
thermostat are supported by a metal enclosure
which serves to house all the electrical connections.
