SX4750A Swinging-Bucket Rotor
Loading the Buckets
CAUTION
If bucket covers are not used, make sure the superstructure of the blood bag
protruding from the cup does not inhibit the bucket from reaching its horizontal
position. If it does, remove the cup from the rotor and reposition the blood bag so
that it seats further into the cup. Allowing the blood bags to contact the rotor yoke
during centrifugation can cause the bucket to come off the pivot pins and can
seriously damage both the rotor and the centrifuge.
If only two filled cups are run, place them in opposing buckets. The other two buckets should
contain similar “blank” loads to prevent imbalance (either empty modular disk adapters or water-
filled blood bags in cups).
Using Cell Culture Flask Adapters
Refer to publication GX-TB-007 for 25-cm

flask adapter information or GX-TB-006 for 75-cm

flask
adapters. (These publications are supplied with the respective adapters.)
NOTE
A dry release agent is used to facilitate removal of cell culture flask adapters from buckets following
centrifugation. To avoid compromising the bucket/cover bioseal, the release agent should not be allowed
on the bucket O-ring. When running cell culture flasks, use the provided adapter to apply the dry release
agent to the bucket cavity and take care to avoid contamination of the O-ring.
Using Bucket Covers
NOTE
Because of the shape of the covers, 130-mm tubes can be used
only
in the center cavities of the
adapters when covers are used.
Install the cover as follows:
1
Make sure that the bucket and the bucket cover surfaces are clean, dry, and undamaged.
2
Make sure that the O-ring (961648) is in good condition and lightly coated with silicone vacuum
grease (335148).
•
Place the O-ring on the ledge inside the bucket.
