7.1 Loading the Tray
A counterweight works to compensate the centrifugal forces of the moving tray.
For physical reasons this counterweight has to be balanced for a certain tray weight.
Equally important is the height of the centre of gravity of the shaken load above the tray (high load
= higher centre of gravity, low load = lower centre of gravity). The higher the total height of the load,
the more the unit can vibrate.
Although INFORS has optimised the band width of the possible loading, the following points should
be respected in order to minimise possible wearing:
- Always load the tray as evenly as possible, so that the weight of the flasks is spread over the
whole tray.
-
Flasks with an extraordinary height and an extremely high centre of gravity should not be
shaken at too high a speed.
-
The allowed loading should generally not exceed or remain under the values stated in the next
chapter.
An under or over loading around these values does not have an acutely damaging effect on the
unit (especially at low speed) but should be avoided if possible.
A constantly higher or lower loading is possible but you have to contact a representative of
INFORS first in order to obtain the necessary advice.
Incorrect loading can lead to vibration and could, for example, lead to the equipment falling
from the bench.
