USING J2 SERIES ROTORS IN THE AVANTI J
!
CAUTION
Do not use the Beckman Coulter JA-10, JS-7.5,
JA-14, or JS-13 rotors in the Avanti J-20XP
centrifuge before reading this information.
CHECKING FOR ROTOR DRIVE PINS
Rotors used in Avanti J series centrifuges must have drive pins in the
rotor drive hole (see Figure 1-5). These drive pins engage with the
centrifuge spindle hub to ensure that the rotor does not slip during
acceleration. Some Beckman Coulter rotors, including the JA-10, the
JS-7.5, the JA-14, and the JS-13, have been manufactured without
drive pins because pins were not needed when these rotors were used
in J2 series centrifuges.
The rotor pins are positioned parallel to the
BECKMAN
name engraved
at the center of the rotor body (see Figure 1-5). Knowing the pin
orientation before you install the rotor will help to ensure that you
position the rotor properly on the hub, minimizing the chance of hub
damage.
Check all J2 series rotors for drive pins before using them in an
Avanti J series centrifuge and do not use rotors without drive pins in
the Avanti J.
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 two metal pins in
the hole, do not use the rotor in the Avanti J. Call your local Beckman
Coulter office for information on returning the rotor to the factory for
upgrading.
USING THE JA-18 ROTOR
In Avanti J series centrifuges, the JA-18 rotor must be run with the
lid attached. See the JA-18 rotor manual (publication J-TB-035) for
complete rotor usage instructions.
