Magnetic Stirrer with Heater
Lab Supplies
This hot plate contains an integrated magnetic stirrer, ideal for use in a laboratory. The dual
controls allow you to set heat output and stirring speed independently. The hot plate can reach a
maximum temperature of 350 °C (662 °F ) with an output of 180 watts. The magnetic stirrer is
adjustable from 100 to 1600 rpm.
A support stand with an adjustable thermometer holder is also included. The support stand extends
about 10" above the hot plate's surface.
Components:
Base with power switch, two knobs and attached hot plate 1" Teflon coated magnetic stir bar
Power cord
Support stand (base rod, extender rod, right angle clamp and thermometer holder)

Operation
To set up the support stand: Screw the two rods together making one support rod. Make sure they
fit tightly. Insert the slotted end of the rod into the plastic holder on the back of the base. Slip the
right angle clamp onto the support rod and tighten the knob. Slide in the thermometer holder and
tighten the other knob. The height of the thermometer holder can be adjusted by moving the clamp
up or down on the support.
To use the hot plate:
1.Make sure the knobs are turned off. The white mark on each knob should be pointing down.

20-30 minutes to boil a large beaker of water. The surface in the middle of the plate can reach
350°C (662 °F ) when the knob is turned all the way to maximum power.
6. Adjust the knob to keep the desired heat level , using a thermometer to check the temperature of
the solution.
