Proper use

The IKA Vibrax VXR basic 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 cont-
ainers 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 passible. 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.

Useful facts

With the purchase of this device, you have acquired a high-quality 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 2200 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 surface. 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 device 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.
Commissioning
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 agitation 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.
If these conditions are met, the device is ready to operate after plugging in the mains
plug. If these procedures are not followed, safe operation cannot be guaranteed and/or
the equipment may be damaged.
Please note the ambient conditions indicated in the Technical details (temperature,
and relative humidity).
After the device has been turned on, the control light comes on three times.
