Press gently but firmly. You will feel a mechanical movement
within the unit and the lid will release.

Balancing the Rotor
Tubes of equal weight and size should be placed opposite each other. Use additional sample
or water in other tubes to provide a balanced rotor. Examples of proper sample balancing are
illustrated next.
WARNING
Spin balanced loads only!
Do not place the tubes asymmetrically nor load unequal volume tubes. Improper place-
ment of tubes will lead to insufficient centrifugation and may cause serious injury or an
accident.
