to directions in the rotor
manual. Ensure that the rotor
is seated on the drive hub.
Avoid bumping the control
panel keys during rotor

!
CAUTION
Rotors used in Avanti J series centrifuges must
have drive pins in the rotor drive hole. These
drive pins engage with the centrifuge drive hub
to ensure that the rotor does not slip during
acceleration. Some Beckman Coulter rotors
were originally manufactured without drive pins
because these rotors did not need pins to run in
older model centrifuges. To check for drive pins,
hold the rotor up or turn it on its side and look
into the drive hole. If you do not see at least two
metal pins near the top of the hole, do not use
the rotor in the Avanti J-E.
