A centrifuge should not show excessive vibrations. It is important to stop the centrifuge and to identify the cause before continuing.
Reasons why a centrifuge show excessive vibrations:
(1) a load that is improperly balanced
(2) a loose or improperly inserted rotor
(3) a problem with the centrifuge motor
(4) problem with the base or feet of the centrifuge causing a wobble
(5) a problem with the surface on which the centrifuge is placed
