  • Page 33: Loading A Rotor For Dual Centrifugation

    ■ Sample containers must be firmly sealed, even more strongly than required for other laboratory work, since they are shaken very vigorously upside-down. Only use containers approved by Hettich and do not exceed their maximum rotational speeds. ■ If not all positions of the adapter are used, the same numbers of sample containers must be distributed over the two adapters, whereby only one (mirrored) symmetrical arrangement may exist inside the adapter.

    Glossary Glossary Dual centrifugation In dual centrifugation, one or more sample containers is centrifuged, each of which rotates additionally about another axis. This special kind of centri- fugation leads to a fundamentally different result than classical centrifuga- tion. While classical centrifugation is a separation method, dual centrifugation is a method for mixing, homogenizing or dispersion.
