Abstract

A sample processing station includes two or more container holders on a platform that is rotatable about a central axis of rotation. Each holder is configured to rotate about a secondary axis of rotation. The station includes a capping/decapping mechanism to cap or decap a container held in one of the container holders and an elevator with a chuck guide that contact the container holder as the chuck is lowered by the elevator to positon the chuck with respect to the cap of the container held in the holder and to hold jaws of the container holder in a closed position. In embodiment, the chuck guide includes a yoke with opposed arms and spindles located near distal ends of the arms that engage beveled shoulders of the container holder.

First claim

The invention claimed is:

1. A method for processing a biological sample comprising:
rotating a first container and a second container about a central axis of rotation while simultaneously rotating each of the first container and the second container about a secondary axis of rotation that is associated with the container and is radially spaced from the central axis of rotation;
positioning the first container beneath a capping/decapping mechanism comprising a chuck configured to grasp a cap of the first container and an elevator configured to move the chuck between a lowered position and a raised position with respect to the first container;
moving the chuck from the raised position to the lowered position with the elevator, grasping the cap of the first container with the chuck, and removing the cap from the first container with the capping/decapping mechanism;
after removing the cap from the first container, moving the chuck and the cap grasped thereby from the lowered position to the raised position with the elevator;
moving a drip tray from a first position not under the chuck to a second position under the chuck moved from the lowered position to the raised position by the elevator;
rotating the first container and the second container about the central axis of rotation until the first container is positioned beneath an automated pipettor;
aspirating an amount of fluid from the first container with the automated pipettor;
rotating the first container and the second container about the central axis of rotation until the first container is positioned beneath the chuck of the capping/decapping mechanism;
moving the drip tray from the second position to the first position;
moving the chuck from the raised position to the lowered position with the elevator, recapping the first container with the capping/decapping mechanism, and releasing the cap from the chuck after the first container is recapped; and
moving the chuck to the raised position with the elevator.

2. The method of claim 1 , further comprising:
rotating the first container and the second container about the central axis of rotation until the second container is positioned beneath the chuck of the capping/decapping mechanism;
moving the chuck to the lowered position with the elevator, grasping a cap of the second container with the chuck, and removing the cap from the second container with the capping/decapping mechanism;
after removing the cap from the second container, moving the chuck and the cap grasped thereby from the lowered position to the raised position with the elevator;
moving the drip tray from the first position to the second position under the chuck moved from the lowered position to the raised position by the elevator;
rotating the first container and the second container about the central axis of rotation until the second container is positioned beneath the automated pipettor;
dispensing an amount of the aspirated fluid from the automated pipettor to the second container;
rotating the first container and the second container about the central axis of rotation until the second container is positioned beneath the chuck of the capping/decapping mechanism;
moving the drip tray from the second position to the first position;
moving the chuck from the raised position to the lowered position with the elevator, recapping the second container with the capping/decapping mechanism, and releasing the cap from the chuck after the second container is recapped; and
moving the chuck from the lowered position to the raised position with the elevator.

3. A method for processing a biological sample comprising:
rotating a first container and a second container about a central axis of rotation while simultaneously rotating each of the first container and the second container about a secondary axis of rotation that is associated with the container and is radially spaced from the central axis of rotation;
positioning the first container beneath a capping/decapping mechanism comprising a chuck configured to grasp a cap of the first container and an elevator configured to move the chuck between a lowered position and a raised position with respect to the first container;
moving the chuck from the raised position to the lowered position with the elevator, grasping the cap of the first container with the chuck, and removing the cap from the first container with the capping/decapping mechanism;
after removing the cap from the first container, moving the chuck and the cap grasped thereby from the lowered position to the raised position with the elevator;
moving a drip tray from a first position not under the chuck to a second position under the chuck moved from the lowered positon to the raised position by the elevator; and
rotating the first container and the second container about the central axis of rotation in a first direction and rotating each of the first container and the second container about its secondary axis of rotation in a second direction opposite the first direction.

4. A method for processing a biological sample comprising:
rotating a first container and a second container about a central axis of rotation while simultaneously rotating each of the first container and the second container about a secondary axis of rotation that is associated with the container and is radially spaced from the central axis of rotation;
positioning the first container beneath a capping/decapping mechanism comprising a chuck configured to grasp a cap of the first container and an elevator configured to move the chuck between a lowered position and a raised position with respect to the first container;
moving the chuck from the raised position to the lowered position with the elevator, grasping the cap of the first container with the chuck, and removing the cap from the first container with the capping/decapping mechanism;
after removing the cap from the first container, moving the chuck and the cap grasped thereby from the lowered position to the raised position with the elevator;
moving a drip tray from a first position not under the chuck to a second position under the chuck moved from the lowered position to the raised position by the elevator;
with a reading device, automatically reading machine-readable indicia on the first container; and
automatically applying machine-readable indicia on a surface of the second container with a printer configured to print the machine-readable indicia directly onto the surface of the second container, the machine-readable indicia applied to the second container including indicia relating to the machine-readable indicia read from the first container.

5. The method of claim 4 , wherein the machine-readable indicia on the first container and the machine readable indicia applied to the second container comprise bar codes.

6. The method of claim 5 , wherein the bar code on the first container and the bar code applied to the second container are at least partially identical.

7. The method of claim 4 , wherein the second container is provided with a blank label and the machine readable indicia is printed onto the blank label.

8. The method of claim 7 , wherein the printer is a thermal printer and the label comprises thermally sensitive print media.

9. The method of claim 4 , wherein the machine-readable indicia read from the first container comprises sample-identifying information.

10. The method of claim 4 , wherein the machine-readable indicia read from the first container comprises sample-identifying information, and wherein the machine-readable indicia applied onto the surface of the second container is at least partially identical to the machine-readable indicia on the first container.
