Apparatus for the precise location of reaction plates
First Claim
1. A microplate apparatus comprising:
- a microtiter plate defining an array of sample wells, each having exterior wall surfaces;
a plate-handling machine having a plate-support surface and a sample-handling or reading device which operates on individual wells in said microtiter plate;
a control unit for controlling the position of said device with respect to defined coordinates on said plate-support surface; and
a locator structure comprising at least one projection extending from said plate-support surface, wherein each of said at least one projection engages said exterior wall surfaces of at least one but no more than four adjacent wells, when said microtiter plate is positioned on said plate-support surface, to fix the position of each well at a known location with respect to said defined coordinates, wherein one or more of said at least one projection and said exterior wall surfaces of one or more wells have complementary shaped regions, with said engaging taking place between said at least one projection and said complementary shaped regions of said wells when said microtiter plate is positioned on said plate-support surface.

Abstract
Generally, the present invention provides a device and method for accurately locating a multi-well plate at a plate-support location, e.g., a work surface, of an automated laboratory machine, such that one or more acting members of the machine, such as an array of pipette tips, optical sensors, or the like, can accurately address and operate on the individual wells. Interior and/or exterior surface regions of one or more wells of a multi-well plate are used as the primary plate features engaged by locating structure of the machine. In one particular embodiment one or more upwardly tapered projections extend from a plate-support surface of a plate-handling machine for mating engagement with the exterior surface regions of one or more wells. In another embodiment, the exterior surface regions along one or more well bottoms are engagingly received within bores, or other receiving structure, formed on the place-support surface of a machine. In a further embodiment, one or more downwardly extending projections depend from an acting-member support, along with the acting members of a machine. Introduction of the projections into some of the wells of a multi-well plate serves to align the acting members with the plate'"'"'s other wells.

16. A microplate apparatus comprising:
-
a microtiter plate defining an array of sample wells, each having exterior wall surfaces;
a plate-handling machine having a plate-support surface and a sample-handling or reading device which operates on individual wells in said microtiter plate;
a control unit for controlling the position of said device with respect to defined coordinates on said plate-support surface;
a locator structure comprising at least one projection extending from said plate-support surface; and
a central cavity formed at a distal end of each of said at least one projection, wherein said central cavity extends from said distal end of said projection toward said plate support surface and opens away from said plate-support surface, said cavity being configured to receive at least a lower region of said exterior wall surfaces of a well, when said microtiter plate is positioned on said plate-support surface, to fix the position of each well at a known location with respect to said defined coordinates. - View Dependent Claims (17)
