The IKA Vibrax VXR is suitable for mixing liquids in bottles, flasks,
test tubes and bowls with a maximum supported weight of 2 kg
(including the attachment).
It is designed for use in laboratories. The motion of the agitation
table or of the containers placed on it is approximately circular.

For usage in accordance with requirements, the machine must
be standing on a stable, even surface that is as slip-free as pas-
sible. In addition, care must be taken that qbjects in the vicinty
are a sufficient distance away from the agitator and that they will
not come too close to the agitator while it is in operation.
Make certain that the unit is standing clear on the spring loaded
feed and that it is not pushing against anything anywhwere.

Please unpack the equipment carefully and check for any dama-
ges. It is important that any damages which may have arisen
during transport are ascertained when unpacking. If applicable a
fact report must be set immediately (post, rail or forwarder).

The delivery scope covers:
A IKA Vibrax VXR and operating instructions.

With the purchase of this device, you have acquired a high-qua-
lity product. The design of the unit and its special shape ensure
ease of handing and problem-free work.

The speed-controlled external rotor asynchronous motor allows
for infinitie speed adjustment in the range from 0 to 2000 rpm.
Electronic motor control holds the set speed constant even if the
weight of the material on the surface increases. The heat given
off by the motor can be used to heat up the holding surface for
the agitation containers.

The motion of the agitation table with the mass to be agitated
exerts a reactive force on the drive. This force is comparable to
an imbalance. As a result, there is an imbalance mass on the
motor that compensates for a part of the imbalance forces.
Because of the different mass of each agitation material, there is
a residual imbalance. This imbalance has the tendency to move
the unit back and forth and to move it around on the adapter sur-
face. This is largely prevented by the spring-loaded feet. The
vibration energy is stored in the springs and directed back into
the machine. If the spring system, the overall mass of the devi-
ce and the speed that is set form a system capable of oscillating,
the oscillating motion of the device may result in resonance. Do
not operate the device at a “critical speed” such as this. Either
reduce the speed and agitate at a lesser intensity or pass through
the critical as possible if you would like to work at a higher speed
or greater agitation intensity.

Check whether the voltage specified on the type plate matches
the mains voltage available.
Place the selected attachment on the agitation table and tighten it
securely with the three clamping screws. Make certain the agita-
tion material is securely in place.
Before tuning on the machine, adjust the turn dial for controlling
the spped so that it is against the left stop.
