Abstract

A method for capping vessels containing biological samples is described providing a cap supply with a plurality of caps for the vessels within compartments in a predefined geometrical arrangement. The cap supply is introduced through an interface into a preanalytical system including a housing, and is reversibly docked to a feeder for inserting the cap supply into the preanalytical system and retrieving it therefrom. Subsequently, a cap is retrieved from the supply by a robotic manipulator, and transported to a workstation holding the vessels. A vessel is then capped using the manipulator. The steps from introducing the cap supply into the preanalytical system to capping a vessel are repeated a certain number of times or until all caps of the supply have been retrieved. Finally, the cap supply is retrieved from the preanalytical system. A preanalytical system and a cap supply for capping vessels containing biological samples is also provided.

First claim

What is claimed:

1. A cap supply comprising a plurality of caps for one or more vessels containing biological samples, wherein the cap supply comprises
a mount including a plurality of compartments that accommodate the plurality of caps, wherein the plurality of compartments are positioned within the mount in a predefined geometrical arrangement,
wherein one or more compartments of the plurality of compartments comprise two or more caps stacked to form one or more layers, each compartment including a socket sized to fit an inner surface of a cap,
each of the one or more layers are separated in the compartment by one or more cradles each comprising two or more protrusions positioned on the one or more cradles between the plurality of compartments, wherein the two or more protrusions facilitate stacking of the one or more cradles and stabilize the plurality of caps, and
the cap supply further comprises a baffle positioned in a center of the cap supply to stabilize the one or more cradles in the cap supply.

2. The cap supply of claim 1 , wherein each of the compartments comprise free space around each cap sufficient for a laterally and vertically moveable robotic gripper to retrieve one of the plurality of caps from one of the plurality of compartments.

3. The cap supply of claim 1 , wherein a bottom surface of each compartment comprises a protuberance for supporting a cap.

4. The cap supply of claim 1 , wherein the cap supply is stackable.
