Corrosion
Do not select rotational speeds higher than the maximums you have
determined to be appropriate for your protocols (in no case above
16 000 rpm in an Avanti J series centrifuge or 14 000 rpm in a
J2 series centrifuge, or above the limit shown in Table 3). When
solutions more dense than 1.2 g/mL are centrifuged in this rotor, use
equation (6) to calculate the reduced maximum allowable speed in
Avanti J series centrifuges. Use equation (7) to calculate the reduced
maximum allowable speed in J2 series centrifuges.
reduced maximum speed = (16 000 rpm)
reduced maximum speed = (14 000 rpm)
Note, however, that the use of this formula may still produce
maximum speed figures higher than the limitations imposed by the
use of certain tubes or adapters (see Table 3). In such cases, use the
lower of the two figures.
Periodically (at least monthly) inspect the rotor body for rough spots
or pitting, white powder deposits—frequently aluminum oxide—or
heavy discoloration. If any of these signs are evident, do not use the
rotor. Contact your Beckman Coulter representative for information
about the Field Rotor Inspection Program (FRIP) and the rotor
repair center.
Rotor
Body
Before using the rotor, inspect the rotor drive pins to ensure that they
are not damaged. Damaged drive pins can prevent the rotor from
seating properly on the centrifuge drive hub (Avanti J series centri-
fuges only). To inspect the drive pins, turn the rotor upside down and
look into the drive hole in the center of the rotor. If the drive pins
appear damaged, contact Beckman Coulter Field Service.
