5. Operation
5.1.
Connect the external power supply to the mains.
Note!
Vessel must be flat-bottomed and fit tightly to the working surface of
the magnetic stirrer (figure 2).
Figure 2.
5.2.
Position the vessel on the center of the platform. Immerse the magnetic stirring ele-
ment.
5.3.
Turn the
Power
switch (fig. 3/1 or 3/3) into the position
On
.
5.4.
Set the required speed using the
Speed
knob (fig. 3/2 or 3/4). Increase the speed.
Note!
A maximum efficient speed is shown in
Table 1
for different stirring
element lengths and mixing volumes. Beyond these numbers, mixing
might be unstable.
Note!
In the model
MMS-3000
, if the stirring element loses positioning, the
motor drops the speed, positions the element and slowly picks up the
speed. If mixing is still unstable due to high viscosity or large mixing
volume, consider lowering mixing speed.
5.5.
After finishing the operation, decrease the rotation speed to the minimum and turn
the
Power
switch into position
Off
.
5.6.
Disconnect the external power supply from the mains outlet.
