Power for the magnetic stirrer (5) is supplied through the power supply unit (9). The
secondary power cable (8) of the power supply unit (9) is connected to the jack at the
back of the magnetic stirrer (5).
The drive and electronic control unit are sealed into the housing of the magnetic
stirrer (2). The housing is completely sealed.
The housing of the magnetic stirrers MAXI DIRECT and MULTIPOINT 6 / 15 is
hermetically encapsulated, as the magnetic drive is enbedded watertight in synthetic
resin inside the housing. This prevents germs from penetrating into the inside of the
magnetic stirrer (5). The magnetic stirrer (5) is cleared for use in safety laboratories
and sterile rooms.
The drive is constructed without the use of moving parts and therefore completely
wear-free. In contrast to mechanical drives, it will nor generate circulating air between
the housing and the environment.
After a startup time of approximately 15 seconds, all magnetic stirring bars are
synchronized to rotate at the preselected speed. The soft start-up function
guarantees a safe acceleration of the magnetic stirring bars and can be monitored via
the digital display (7). The soft start-up function is switched on when a dot appears
next to the rotation speed in the digital display (79. As soon as the selected rotation
speed has been reached, the dot in the digital display (79 vanishes.
Stirring vessels and magnetic stirring bars do not fall within the scope of delivery.
POLY 15:
You start and terminate the stirring operation with the START/STOP key
(1). The
rotation speed is set with the
key (2) and with the
key (3). The digital display (7)
shows the currently set rotation speed.
MAXI DIRECT and MULTIPOINT 6 / 15:
Both the MAXI DIRECT magnetic stirrer as well as the MULTIPOINT magnetic
stirrers are additionally equipped with the MODE key (4). You can select either one
of four rotation speeds: 5/10/15/20 W.
You start and terminate the stirring operation with the START/STOP key
(1). The
digital display (7) shows the mode selected last. You switch to the power display or
the rotation speed display via the MODE key (4). The desired power or rotation
speed can be selected with the
key (2) and the
key (3).
After selecting the stirring power, the digital display (7) switches automatically to the
rotation speed display after approximately 5 seconds.
