Precautions while using Centrifuge
During centrifugation 1 Close lids at all times during operation. Never open a centrifuge until the rotor has stopped. 2 Do not exceed safe rotor speed. 3 The operator should not leave the centrifuge until full operating speed is attained and the machine appears to be running safely without vibration. 4 Stop the centrifuge immediately if an unusual condition (noise or vibration) begins and check load balances.
