Use only the rotor / bucket (round or rectangular) / adapter combinations approved by
Eppendorf. Check that all buckets are fully attached and are able to swing out freely. If
you use overlength tubes, it is essential to carry out a manual swing test with empty
tubes!
For mechanical stability, all the places must be fitted with identical buckets. The buckets are
sorted by weight. The weight class is embossed on the side of the bucket:
e.g. 90 (the last 2 digits in grams). Opposing buckets must be of the same weight class. When
reordering, please quote the weight class required.
Before inserting the buckets in the grooves make sure the grooves are clean. Dirty grooves or
pegs will prevent the buckets from swinging out evenly. If the rotor is not fully loaded, spread
the load in the buckets evenly across the pegs.
The specified weight imprinted on the rotor is the gross weight rating of the round or rectangular
bucket (including adapter, tubes and contents).
Always weigh the bucket and the load together.
