5.2.4 Installation of Accessories
• Only use vessels that are suitable for the rotor (see chapter
10 "Suitable
Accessories", page
56).
• Load all of the compartments of the swing-out rotors.
• Always load the opposite compartments of the rotors with the same
accessories and filling to avoid imbalance.
• Centrifugation with low capacity
: For the
example, a swing-out rotor
(16 x 15 ml) that is to be equipped with
eight tubes only was used. The tubes
must be installed symmetrically so that the
buckets and their suspensions are loaded
evenly.
• Centrifugation with different tube sizes:
Working with different tube sizes is
possible. In this case, however, it is very
important that opposite inserts are
identical. The example shows a swing-out
rotor with buckets and 2 x the insert 100
ml and 2 x the insert 4 x 15 ml with the
corresponding glass or plastic tubes.
Another example is the angle rotor 24 x 2.2 ml: The tubes must be installed
symmetrically so that the rotor is loaded evenly.
