VI. 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 motorshaft tightly together by tightening the screw nuts (the
move should be verygentle and substantially shaking and pressing should be avoided, so as to
protectthe flexible support system of the motor. Then, place the adapter with testtubes on the rotors
and rotate the rotors. The rotors should be turnedflexibly, the adapter should be rotated freely, and
there should be no block orcollision.
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.
