05 The Operation Procedures
Step 1: Place the centrifuge machine on the platform and ensure its balance. Shake the
machine with hands to check out whether the machine has been placed stably or not.
Step 2: Plug the supply cord into the outlet and press down the power switch ( the power
switch is on the right bottom of the machine ).
Step 3: After pressing down the button of “ STOP & OPEN”, put the rotors on the motor
shaft, and connect the rotors with motor shaft tightly together by tightening the screw nuts
( the move should be very gentle and substantially shaking and pressing should be avoided,
so as to protect the flexible support system of the motor. Then, place the adapter with test
tubes on the rotors and rotate the rotors. The rotors should be turned flexibly, the adapter
should be rotated freely, and there should be no block or collision.
Step 4: Place the centrifuge tubes into the test tubes. The centrifuge tubes should be placed
symmetrically, and the test solutions in the tubes should be even, so as to make sure the
equilibrium operation of the machine.
Step 5: Cover the faceplate and check out whether it is covered tightly, or the centrifuge
machine cannot be operated.
Step 6: Set up the rotor mode, the rotating speed and the needed time.
The control panel of the machine is as shown below.
