Abstract
An analytical rotor which comprises a receptacle for receiving a post on a centrifuge and a sealed rigid container in the rotor body proximate to the receptacle is provided. The seal on the container is opened when the post is inserted in the receptacle, thereby releasing a liquid in the container. The seal is preferably opened through the displacement of the container caused by positioning of the rotor on the centrifuge post.
