1. Introduction
The MH 15 heating magnetic stirrer is used to heat and mix liquids inside a suitable container placed on the aluminium plate.
The stirring is possible thanks to a magnetic drive stir bar placed into the vessel.
The instrument is used in the laboratory for general use and for all those applications that require precise regulation of the
heating plate temperature and stirring speed.
The Aluminum alloy heating plate ensures:
•
Optimum heat distribution and a high specific power thanks to the circular configuration
•
Temperature homogeneity
•
High resistance to thermal stress and thermal shock
The powerful brushless motor is able to stir from 100 up to 1500 rpm.
SpeedServo technology maintains constant speed as viscosity changes.
Note: it's important to choose the most suitable magnetic stirring bar related to the type and the quantity of the liquid to be
stirred as well as to the type of the beaker. Size and shape of the magnetic stir bar determines the stirring efficiency at a ny
given speed. The stirring bar which satisfies most applications is code A00000356 (8 x 40 mm).
2. Installation
•
Unpacking
➢ Check the integrity of the unit after unpacking
•
The box includes
➢ MH 15 heating magnetic stirrer
➢ Instruction manual
➢ Power cable
•
Installation
➢ Place the unit on a non-flammable surface
➢ Make sure that the technical specification of the unit and of the power supply line are the same
➢ Make sure that the electrical network is grounded
➢ Make sure that the main switch is on position "0" (OFF)
➢ Connect the instrument to an easily accessible socket (compliant with the current safety norms), using only the
provided power cable
Note: keep the power cable far away from the hot plate.
➢ Place the container with the liquid and the stir bar on the stirring plate
