Imbalance Indicator - VWR Micro Star 30R Instruction Manual

INSTRUCTION MANUAL

3.6 IMBALANCE INDICATOR

The centrifuge is fitted with an imbalance detector, to ensure safety.
Imbalance at high speed may indicate a tube breakage or leak or rotor crash. Therefore
additional care should be taken depending on the samples loaded.
You must always load the rotor with test tubes symmetrically. You may only use approved test
tubes. Weight difference of the samples in test tubes should be as low as possible in order to
avoid potential damages to the motor and to minimize running noise and vibration.
Following are examples of correctly and wrongly loaded rotors:
