4. Grasp the daisy knob and turn it to the left (counterclockwise)
until it disengages.
5. Remove the lid and set it aside. If the lid cannot be removed, first
pull up on the tie-down knob to release vacuum inside the rotor,
and then remove the lid.
!
CAUTION
Always loosen the round tie-down knob to
disengage the rotor from the centrifuge drive
hub before attempting to loosen the daisy knob.
The dual-locking lid assembly can be damaged if
the daisy knob is loosened while the rotor is still
engaged with the hub.
Single-Locking Lid
1. Unscrew the tie-down knob to release the rotor from the drive hub.
2. Remove the lid and set it aside.
3. Lift the rotor straight up off the drive hub. Do not lift the rotor by
the tie-down knob.
NOTE
Lubricating the centrifuge drive hub with
Spinkote should prevent the rotor from sticking
in J2 series centrifuges. In Avanti J series centri-
fuges, the drive hubs do not need lubrication
because Delrin rings on the hubs prevent
sticking.
The JLA-16.250 rotor uses the bottles and tubes listed in Table 3.
Be sure to use only those items listed and observe the maximum
fill volumes and speed limits shown. (Maximum fill volume is the
maximum amount of fluid that can be centrifuged in the listed
