SX4750A Swinging-Bucket Rotor
Operation
2
Grasp the carriage by the handles and lower it into the carrier.
3
Make sure that carrier cover gaskets are in good condition and secured to the covers.
IMPORTANT
The seal surfaces of the gaskets and carriers must be free of dust, fibers, and other
contaminants that could affect the seal.
4
Put covers on the carriers with the latches perpendicular to the pin sockets.
•
Snap the latches down and secure them under the carrier rim.
5
Attach each carrier to the yoke by aligning the grooves in the sides with the pivot pins, then
sliding the carrier down until the pivot pins are seated in the pin pockets.
CAUTION
All four positions must contain buckets or carriers during a run. Never run the
rotor with only two positions filled. If two tube-and-bottle buckets and two
multiwell-plate carriers are run, position the similar buckets opposite each other.
Select multiwell-plate carrier speed when running mixed sets.
6
Gently swing the carriers to ensure that they are properly seated on the pivot pins.
Operation
1
Refer to the instrument instruction manual for centrifuge operation.
NOTE
When using multiwell-plate carriers, enter SX4750A as the rotor and limit top speed of the
instrument to 3750 RPM in an Allegra X-12 series centrifuge, 4000 RPM in an Allegra X-14 series
centrifuge, or 4450 RPM in an Allegra X-15R centrifuge (when running up to three stacked
Beckman Coulter plates separated by cap strips; reduce speed to 2700 RPM if running four stacked
plates).
Set rotor speed using RPM values only. To set speed to a specific RCF, use the RPM-to-RCF
conversion chart (GX-TB-015) to determine the applicable RPM to enter.

for information about speed limitations.
