Abstract

System, apparatuses, and methods for performing automated reagent-based analysis are provided. Also provided are methods for automated attachment of a cap to a reaction receptacle, and automated removal of a cap from a capped reaction receptacle.

First claim

What is claimed is:

1. A single piece multi-well tray for use in an automated instrument and comprising:
an elongated base having a first end and a second end, said base comprising a top surface and opposed side walls extending from the top surface to a bottom surface, a first end wall extending between said side walls, and an arm extending outwardly from the first end of the base and configured to be engaged by a transport mechanism for transporting the tray within the instrument, wherein the arm comprises a bridge extending outwardly from the first end wall and a post having one end attached to the bridge and an opposite end that is not attached to the bridge and wherein the post extends from the bridge so as to define a gap between the opposite end of the post and the first end wall;
a plurality of wells depending from the top surface and disposed between the opposed side walls, each having an opening at the top surface, wherein the wells are arranged in at least one row extending between the first end and the second end of the base, and wherein the wells do not extend below the bottom surface of the side walls; and
snap fingers disposed at the second end of the base and configured to grasp an element of the instrument for securing the tray to the element, wherein the snap fingers comprise opposed spaced-apart tabs defining a slot therebetween configured to receive the element of the instrument.

2. The multi-well tray of claim 1 , wherein the post extends in an orientation substantially perpendicular to a plane of the top surface.

3. The multi-well tray of claim 1 , further comprising at least one frangible seal secured to the top surface and covering the opening of a corresponding well.

4. The multi-well tray of claim 1 , wherein each well comprises a side wall and a bottom wall, and at least one of the wells further comprises one or more features selected from the group consisting of a plurality of bumps, a concave groove, a convex ridge, and a set of grooves and/or ridges comprising a crisscross pattern formed on an inner surface of the bottom wall.

5. The multi-well tray of claim 1 , wherein at least one of the wells comprises one or more retention features selected from the group consisting of a tapered ring insert, a collar, and a fingered collar, wherein the one or more retention features are disposed within the well and are sized to retain a lyophilized reagent within the well.

6. The multi-well tray of claim 1 , wherein a perimeter wall of the base defines the opposed side walls and a front end wall.

7. The multi-well tray of claim 1 , wherein the wells are arranged in two parallel rows of wells.

8. The multi-well tray of claim 1 , wherein the snap fingers comprise a portion of the bottom surface.

9. The multi-well tray of claim 1 , wherein the opposed tabs are oriented in a direction extending from the second end of the base toward the first end of the base.

10. The multi-well tray of claim 1 , wherein the opposed tabs flare away from each other at their ends.

11. The multi-well tray of claim 9 , wherein the opposed tabs flare away from each other at their ends.

12. The multi-well tray of claim 1 , wherein the base is defined by a perimeter wall that defines the opposed side walls, a first end wall, and a second end wall with the opposed tabs extending inwardly from the second end wall, wherein the first end of the base comprises the first end wall, and wherein the second end of the base comprises the second end wall.

13. The multi-well tray of claim 9 , wherein the base is defined by a perimeter wall that defines the opposed side walls, a first end wall, and a second end wall with the opposed tabs extending inwardly from the second wall, wherein the first end of the base comprises the first end wall, and wherein the second end of the base comprises the second end wall.

14. The multi-well tray of claim 10 , wherein the base is defined by a perimeter wall that defines the opposed side walls, a first end wall, and a second end wall with the opposed tabs extending inwardly from the second wall, wherein the first end of the base comprises the first end wall, and wherein the second end of the base comprises the second end wall.

15. The multi-well tray of claim 11 , wherein the base is defined by a perimeter wall that defines the opposed side walls, a first end wall, and a second end wall with the opposed tabs extending inwardly from the second wall, wherein the first end of the base comprises the first end wall, and wherein the second end of the base comprises the second end wall.
