1. Introduction
AMI4 is specially designed for titrations, and particularly for those in which optimum lighting condition are needed in order to
see the final point of colour change well. This magnetic stirrer is illuminated with 4 separately controlled positions.
The lighted stirrer plate is particularly recommended for titrations that have weak colour changes during conversion. By the
switch it's possible turn on the lighted stirrer plate. The stirrer stays cold even after several days of continuous use. This
feature makes it highly appreciated in microbiology and biochemistry.
NOTE: it is 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 application is code 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 AMI4
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 flask 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. The Stirrer Led shows when the stirring
is running. Each work position is equipped with a hole in the bottom through which it's possible to modify the illumination
brightness using a flat screw driver.
