General instructions
CAUTION – WARNING!
In order to avoid damage to the centrifuge and accessories, the
following instructions must be precisely followed!
Bucket positions
WARNING! Illustration 16 - prohibited!
Never start the centrifuge when not all of the carrying buckets
are inserted!
For the swing rotor, all positions must be filled with buckets of
the same type (same order number)!
Illustration 17 – acceptable
Partial loading is possible (however all positions must be filled with
buckets)
The buckets could have distinguishing characters for determining the
varying weights.
Only buckets of the same weight class may be placed opposite each
other!
Symmetrical loading
The following illustrations show how vessels can be incorrectly or
correctly placed in the rotor:
Illustration 18 – not acceptable!
The retaining bolts are unequally burdened.
The vessels must be distributed within a bucket so that the load on
the retaining bolts is equal!
For partial loading, see illustration 17 or illustration 20.
Illustration 19 – incorrect!
Imbalance due to unequal swinging of the buckets!
The rotor must always be symmetrically loaded and vessels and
inserts equally distributed.
Illustration 20 correctly loaded
No imbalance because all vessels are symmetrically distributed.
Of all the variants shown (a, b, c), b is the best possible.
