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. Assembly and installation

Upon receipt and after having removed the packaging, please check the integrity of the instrument. The box includes:
•
Magnetic stirrer M 3
•
Plug for power supply

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.

4. Maintenance

No routine or extraordinary maintenance is necessary apart from periodically cleaning the unit as described in this manual.
In compliance with the product guarantee law, repairs to our units must be carried out in our factory, unless previously
agreed otherwise with local distributors. The instrument must be transported in its original packaging and any indications
present on the original packaging must be followed (e.g. palletized).

4.1 Cleaning

Disconnect the unit from the power supply and use a cloth dampened with an non-inflammable non-aggressive detergent.
