1. Introduction
The HSC heating magnetic stirrer with ceramic plate, is used in the laboratory for general use and for all those applications
that require a precise regulation of the stirring speed and of the heating plate temperature.
The ceramic heating plate (1) means that higher temperatures can be obtained compared to the traditional aluminium
heating plate and it takes less time to heat the sample. Ceramic is an inert and very hard material and is resistant to almost
any type of chemical or mechanical aggression; it's surface characteristics remain unaltered over time.
The HSC is used to mix liquids using a magnetically driven stir bar placed inside the vessel. The size and shape of the
magnetic stir bar determines the stirring efficiency at any given speed. It is therefore advisable to choose the most suitable
magnetic stir bar in relation to the quantity and characteristics of the liquid and the type of vessel used.
The stirring bar which satisfies most applications is code A00001060 (10x40 mm).
The instrument is turned on using the ON/OFF button (2). The stirring speed (3) and the temperature (4) of the heating plate
are adjusted using the relative knobs on the front panel.
The stirrer led (5) indicates that the stirring function is active; the heating led (6) indicates that the heating function is active
NOTE: If the heating function is used the vessel must be made of a suitable material to withstand the foreseen temperature.

2. Assembly and installation
Check the integrity of the unit after unpacking. The box includes:
•
•
•
HSC Heating Magnetic Stirrer
Power supply cord
Instruction manual
2.1 Electrical connections
After having unpacked the instrument, place the unit on the laboratory bench.
Before connecting the instrument to the power supply, make sure that the values on the rating plate correspond to those of
the power supply. The equipment shall be connected to a power socket with protective earth connection, using only the
power supply cord provided with the instrument.
Ensure that the socket and the relative cut-off device conform to current safety norms and are easy to reach.
NOTE: the mains cable must remain far away from the hot plate.
2.2 Start-up
Rotate the speed (right) and temperature (left) knobs completely to the left. Place the flask containing the sample and a
suitable magnetic stirring bar on the stirring plate. Then, set the speed and temperature by turning the dedicated knobs.
3. Operating controls
Connect the unit to mains and turn it on using the on-off button. The green led indicates that the instrument is On.
Start the stirring function by turning the stirrer knob "Stirrer rpm" on the front panel. Speeds of from 50 to 1300 rpm can be
selected using the analogical scale around the knob. To start the heating function turn the heating knob "Heating °C" on the
front panel. Temperatures of from 5 to 400 °C can be selected. The knobs on the front panel are easily accessible and are
well away from the heating plate in order to ensure maximum operator safety as well as safeguarding the electronic
components inside the unit.
NOTE: in case of black-out, the device will automatically restart once the power is back.
