Plate holder
First Claim
1. A holder for a sample-holding plate defining one or more sample-holding wells, said holder comprising a back wall and a side wall and defining a space between said back wall and said side wall into which a sample-holding plate can be placed,characterized in thatsaid holder further comprises a retainer mounted to a holder frame for movement relative to said space between a first position for pressing a sample-holding plate placed in said space against both said back wall and said side wall and a second position retracted from pressing the sample-holding plate, said retainer comprising an arm defining a pressing surface disposed for pressing engagement with the sample-holding plate.

Abstract
A holder for sample-holding plates has a retainer for pressing a plate placed in the holder both against the back wall and against a side wall. Thus a plate of a certain type will always settle in the same position in the holder. It is also possible to use in the holder plates of many sizes, which can be kept in place during handling owing to the retainer. The device is suitable for use in particular in assay methods in which samples to be assayed are handled on plates having a plurality of wells, for example in optical analyzers or other apparatuses.

11. A holder for a sample-holding plate defining one or more sample-holding wells, said holder being mounted in a movable carrier and comprising a back wall and a side wall and defining a space between said back wall and said side wall into which a sample-holding plate can be placed, said holder further comprising a retainer mounted to a holder frame for movement relative to said space between a first position for pressing a sample-holding plate placed in said space against both said back wall and said side wall and a second position retracted from pressing the sample-holding plate, said retainer comprising an arm defining a pressing surface disposed for pressing engagement with the sample-holding plate, and said retainer having a basic shape of an obtuse V and being pivoted by its apex to a vertical pin in the moveable carrier, and said holder further comprising a spring linked to said retainer with a first end against a frame of the moveable carrier and an opposite second end against said retainer.
-
18. A holder for a sample-holding plate defining one or more sample-holding wells, said holder comprising a back wall and a side wall and defining a space between said back wall and said side wall into which a sample-holding plate can be placed,
characterized in that said holder further comprises a retainer mounted to a holder frame for movement relative to said space between a first position for pressing a sample-holding plate placed in said space against both said back wall and said side wall and a second position retracted from pressing the sample-holding plate, said retainer comprising an arm defining a pressing surface disposed for pressing engagement with the sample-holding plate, said holder being mounted in a moveable carrier and having a front edge opening into said space in a specific loading position of said moveable carrier at which the sample-holding plate is placed into said space or removed therefrom by substantially horizontal motion, and said holder further comprising pins detachably mounted at said opening for resisting placing or removal of the sample-holding plate in said space when the moveable carrier is removed out of its specific loading position.
-
19. A holder for a sample-holding plate defining one or more sample-holding wells, said holder comprising a back wall and a side wall and defining a space between said back wall and said side wall into which a sample-holding plate can be placed,
characterized in that said holder further comprises a retainer mounted to a holder frame for movement relative to said space between a first position for pressing a sample-holding plate placed in said space against both said back wall and said side wall and a second position retracted from pressing the sample-holding plate, said retainer comprising a lever arm mounted for pivoting movement about a pin extending generally vertically from said holder frame.
