Operation
Power Switch
The Isotemp Advanced unit has Power Switch on the left
side of the unit. The unit is powered on by pressing the
Power Switch. When the unit is turned on, the unit will
initialize and then model name will be displayed on the first
row of display screen while software version in second
row. To turn off power to the unit, press the Power Switch
off. It is recommended to unplug the unit when not in use
for 24 hours or longer.
Setting the Stirring Speed
The Isotemp Advanced stirring unit has an electronic
feedback speed control which will maintain a precise
speed setpoint from 50 rpm through 1500 rpm. (Maximum
speed is dependent on viscosity of the solution.) The
Isotemp Advanced stirring hot plates are equipped with a
strong magnet and high torque motor.
To set the stirring speed, press "SPEED" key located
under display. Then the speed setpoint will flash. Use the
knob on the front panel to set a speed. Turn the knob
clockwise to increase the speed or counterclockwise to
decrease the speed. When desired setpoint has been
reached, press the "SPEED" key or wait 10 seconds, the
speed setpoint will no longer flash indicating that it has
been set.
Push the knob to turn on stirring, once the unit begins
stirring, the display will indicate both actual speed and
setpoint. To stop the stirring action without changing your
setpoint press the knob once. To resume stirring at the
set speed, press the knob again.
To turn stirring off, press "SPEED" key under the display
and turn the knob counterclockwise until the display reads
"OFF".
Warning
Use caution when heating volatile
materials; top surface and element can
reach the "Flash Point Temperature" of
many chemicals. These hot plates are not
explosion proof. Fire or explosion may result.
Unit contains components which may ignite
such materials.
Use appropriate hand and eye protection
when handling hazardous chemicals.
"Caution: Hot Top. Avoid Contact." The top
plate of the unit can remain hot for some
time after use. A 'CAUTION - HOT TOP" light
will remain on until top plate temperature
cools to below 50°C.
Note
Boiling times are dependent on solu-tion
volume and the surface area of the flask that
is exposed to the hot plate. For example,
when heating the same amount of solution in
a 2L flask vs. a 1L flask, the solution will heat
about 20% faster.
Note
The top plate temperature will be higher than
the solution temperature.
