Installation of Accessories
•
Only use vessels that are suitable for the rotor (see chapter 10 "Suitable
Accessories", page 51 ff).
•
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 8 x 15 ml (Fig. 5.6) and an angle rotor 30
x 15 ml (Fig. 5.7) that are to be equipped with 4 tubes only were used.
The tubes must be installed symmetrically so that the rotor is loaded evenly.
5.2.4.1 Carrier Systems
In order to ensure easy handling, even if vessels of various sizes are used, a
carrier system was developed.
•
Load the opposite carriers with the same number of vessels and with the
same weights in order to avoid imbalance.
•
If all of the compartments of a carrier are not used, the buckets must be
loaded evenly. Loading the edges of a bucket only is not permissible.
5.2.4.2 Tubes
•
Load the tubes outside of the centrifuge. Liquids in the buckets or multiple
carriers cause corrosion.
•
Fill the tubes carefully and arrange them according to their weight.
Imbalances result in the excessive wear of the bearings.
•
In high-speed angle rotors, the vessels must be filled up to their useful
volume (= the volume stated for the vessel). If the vessels are only partially
