Reagent container for analytical rotor
First Claim
Patent Images
1. An analytical rotor for use with a centrifuge, the rotor comprising:
- a rotor body having an axis of rotation, a top surface, and a bottom surface;
a receptacle on a surface of the rotor body for receiving a post on the centrifuge;
a container holding a liquid and comprising a seal, wherein the container is movably positioned in a chamber of the body adjacent to the receptacle;
means for engaging and holding a portion of the seal against displacement relative to the chamber such that insertion of the post into the receptacle displaces the container to open the seal and releases the liquid.

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.

12. An analytical rotor for use with a centrifuge, the rotor comprising:
-
a rotor body having an axis of rotation, a top surface, and a bottom surface; a receptacle on a surface of the rotor body for receiving a post on the centrifuge; a container holding a liquid and comprising a rigid side having a scribe mark, wherein the container is movable positioned in a chamber of the body adjacent to the receptacle; means for engaging and holding a portion of the container against displacement relative to the chamber such that insertion of the post into the receptacle displaces the container, thereby splitting the rigid side along the scribe mark and releasing the liquid. - View Dependent Claims (13)

14. An analytical rotor for use with a centrifuge, the rotor comprising:
-
a rotor body having a bottom surface; a receptacle on the bottom surface of the rotor body for receiving a post on the centrifuge; a sealed container holding a liquid and comprising a seal, wherein the container is movably positioned in a chamber of the body adjacent to the receptacle; means for engaging and holding a portion of the seal against displacement relative to the chamber such that insertion of the post into the receptacle as the rotor is mounted in the centrifuge displaces the container to thereby open the seal and deliver the liquid through a channel to a receiving chamber as the rotor is spun. - View Dependent Claims (15)
