voltage.

Packing List:

Each stirrer, hotplate, or stirring hotplate comes complete with an
instruction sheet and warranty card. Each stirring unit is supplied
with one stir bar.

Controls and Indicators:

The unit contains the following controls and indicators: (Depending
on which unit you have, some of the functions described may not
apply to your unit.)
Power Indicator: Lights when unit is plugged in and power is being
supplied to the unit. There is no separate power switch.
Reset Key: Resets set stir speed and temperature to minimum.
C/F Key: Sets the indicated temperature in degrees Centigrade or
Fahrenheit.
Hot Top Indicator: Lights when the temperature of the top surface is
above 40°C and is no longer safe to touch. Unit must remain plugged
in for indicator to function.
External Probe Indicator: Lights when external temperature probe is
plugged in.
Stir Key: Sets stirring action on or off.
Stir Up and Down Arrow Keys: Set stir speed from approximately 60
to 1,200 RPM. Hold the up arrow key to increase the set speed. Hold
the down arrow key to decrease the set speed.
Measured Speed Display: Shows actual stir speed.
Set Speed Display: Shows setting of desired stir speed.
Heat Key: Sets heater on or off.
Heat Up and Down Arrow Keys: Sets heat level supplied through the
top plate. Hold the up arrow key to increase the set temperature.
Hold the down arrow key to decrease the set temperature.
Heat Indicator: Lights when the heating function in enabled. (Not on
stirrer only models.)
Measured Temp Display: Shows actual temperature of top plate (or
sample when using optional temperature probe).
Set Temp Display: Shows setting of desired temperature.
Plate and Probe Indicators:
displayed is being measured at the top plate or through the optional

displayed.
Operation:
Follow this general procedure when operating the stirrer, hotplate, or
stirring hotplate.
1. Before using the unit, be sure to read, understand, and follow all
safety information contained in these instructions.
2. Using the supplied power cord, plug unit into suitable power
outlet. The power indicator lights to show that the unit is
operational. The unit starts operating at the previous values for stir
speed and temperature. To stop the unit from functioning and to
return the stir speed and temperature to zero, press the reset key.
3. To set the stir speed, press the stir key so the stir indicator lights.
To increase the stir speed, press and hold the stir up arrow key. To
decrease the stir speed, press and hold the stir down arrow key. As
you hold either of the arrow keys, the value will start changing
gradually, then change more quickly as you continue holding the
arrow key. The display shows the measured speed and set speed.
To turn off the stir function, press the stir key so the stir indicator
goes off.
Note: If the stirring bar decouples when boiling liquids, decrease
stirring speed to facilitate recoupling.
4. To set the temperature, press the heat key so the heat indicator
lights. Note that the unit is indicating °C (Centigrade) or °F
(Fahrenheit). To change the indication to Centigrade or
Fahrenheit, press the C/F key. To increase the temperature, press
and hold the heat up arrow key. To decrease the temperature,
press and hold the heat down arrow key. The display shows the
measured temperature and set temperature. To turn off the heat
function, press the heat key so the heat indicator goes off.
Note:
•
When using the internal sensor (not external, optional
probe), it will be necessary to set the temperature higher
for the sample to achieve the desired temperature. How
much more will depend on size, shape, and mass to be
heated. The internal sensor measures middle top
surface temperature and does not include an offset for a
sample of unknown size, shape, and mass. Two
examples for explanation purposes: Single 1"x 3" slide
set in the center of the top to evaporate liquid will be
very close to the correct temperature on the display. A
liter of water in a beaker will be off considerably
because of the large mass and surface area to dissipate
heat.
•
To get the fastest heat up times set control to maximum
set point. Lower set points will ramp slower to desired
temperature. This is true with either sensor (internal
sensor or external probe).
WARNING:
During normal operation of the hotplate or stirring hotplate, the top
plate can become hot enough to cause severe burns. Avoid contact.
The top surface of the hotplate can remain hot without visual
indication for some time after heat is turned off or the power cord is
unplugged.
5. To stop the unit from functioning and to return the stir speed and
temperature to minimum, press the reset key.
Included with stirring units is a stir bar coated with Teflon
Fluorocarbon Resin. (Teflon Fluorocarbon Resin is a trademark of
E.I. DuPont de Nemours and Company.)
The hotplate/stirrer unit is equipped with a built-in support rod holder
located on the back of the unit. It will accommodate rods up to 0.5"
(13mm) diameter. Accessories are available from Cole-Parmer (in
the catalog under the Flexaframe and Castaloy sections) for this unit.
