Preparation And Loading - Beckman Coulter Avanti J-20 XP Instruction Manual

PREPARATION AND LOADING

Action
1. Turn the power switch on (I).
2. Step on the foot pedal to
open the door.
3. Install the rotor according to
the instructions in the rotor
manual. Always run the rotor
with a balanced load. (If you
are using a swinging bucket
rotor, fill all positions on the
yoke with buckets. If you are
®
using a J-Lite rotor with
cannisters, place a cannister
in each rotor body cavity.)
4. Securely attach the rotor lid
knob, or tie-down knob in
rotors without lids, to the
drive shaft by turning it to the
right (clockwise).
For fast temperature equilibration, precool or prewarm the rotor to
the required temperature before the run.
Result
Power is applied to the system, and the display illuminates.
The door opens.
!
CAUTION
Do not drop the rotor onto the drive hub. The
drive shaft can be bent if the rotor is forced side-
ways or dropped onto the hub. Install the rotor
by centering it over the hub and carefully
lowering it straight down.
NOTE
If the knob turns loosely and you do not feel
threads engaging, the rotor drive hole pins may
not be properly seated on the centrifuge hub. Lift
the rotor up above the hub, rotate it slightly, and
lower it onto the hub again. Tighten the knob.
