1. Introduction
The M 3 magnetic stirrer is a small, simple and effective stirrer. Thanks to the white cover surface it is specially designed for
microtitrations, and it is extremely useful where reliable and small instrument is needed. The stirrer stays cold even after
several days of continuous use. This feature makes it highly appreciated in microbiology and biochemistry.
The technopolymer structure is studied and tested in order to give to the instrument an excellent resistance to the attack of
chemical agents and to corrosion in general. The stirring speed can be set within a range of 0 - 1100 rpm using the knob on
the front panel. The Stirrer led shows when the stirring is running.
NOTE: it’s important to choose the most suitable magnetic stirring bar related to the quantity and the liquid to be stirred as
well as to the type of the beaker. The magnetic stirring bar that satisfies most of the application is A00001056 (6x35mm).

2.1 Electrical connection
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. Connect the unit to the power supply using the transformer supplied.
Ensure that the socket and the relative cut-off device conform to current safety norms and easy to reach.
2.2 Start-up
Rotate the speed knob completely to the left. Place the flasks containing the sample and a suitable magnetic stirring bar on
the stirring plate. Then, set the speed by turning the speed knob.

3. Operating controls
Turn the stirring speed knob on the front panel in order to start the stirring function.
It is possible to select speeds between 0 and 1100 rpm.
When the led is lighted it means that the stirring is on
4. Maintenance
No routine or extraordinary maintenance is necessary apart from periodically cleaning the unit as described in this manual.
