Environmental conditions:

The instrument must not be operated at temp. Exceeding 50ºc. (Must be operated at the usual room temperature away from direct air draught and / or direct sunlight.)

Operation:

Connect the stirrer to the main supply
Switch on the mains, mains led will glow
Keep liquid-filled flat bottom flask on the mantle of worthy size
Put Teflon magnetic bit inside the flask.
Before starting the unit, place the stirring bath in the flask, so it can take its centre position.
In case, if this is not in the centre, make sure the stirring bar to be in the centre position.

Adjust the speed of the stirrer by speed knob to the needed speed
Switch on heating by turning out the heat control knob in the clockwise direction
Adjust it to the required heating
The heat control knob controls the wattage of the heating mantle and thus the temperature of liquid put in a glass flat bottom flask.
 
Precaution:

1) Take care while keeping Teflon magnetic bit into the glass vessel
2) Put glass vessel on heating mantle carefully
3) Don’t spill off the liquid on the Scientific instruments
4) After utilization dry and wash Teflon magnetic bit
