Luminescence exposure apparatus
First Claim
1. Luminescence exposure apparatus for conducting luminescence reaction tests on specimens contained within a test well in a reaction test apparatus, comprising:
- a lower housing havinga flat, upwardly facing internal surface comprising means for receiving a piece of film thereupon.a mask covering the upwardly facing surface and having an opening therethrough positioned to correspond to the location of the test well in the reaction test apparatus,biasing means on the mask for resisting the downward movement of the reaction test apparatus, when the reaction test apparatus is placed upon the mask, anda movable shutter between the upwardly facing internal surface and the mask; and
an upper housing includingtranslation means for controllably urging the reaction test apparatus downwardly against the resistance of the biasing means, thereby contacting the bottom of the reaction well in the reaction test apparatus with the piece of film in the lower housing.

Abstract
Apparatus for performing and measuring chemical reactions includes a reaction test apparatus having reaction wells wherein reactants are controllably mixed, and exposure apparatus which receives and positions the reaction test apparatus adjacent a photographic film. Each of the reaction wells includes at least two reaction chambers, arranged in a side by side fashion. All but the final reaction chamber have upwardly sloping sides, so that liquid placed in one reaction chamber can flow to the next reaction chamber when the apparatus is tilted. In a preferred embodiment, the reaction wells are supported in a plate that is structurally integral with the wells but separates the wells from each other. The test plate is retained in the exposure apparatus, and liquid is controllably flowed from one reaction chamber to the next by tilting the exposure apparatus. The apparatus of the invention is particularly suited for measuring reactions that produce luminescence of short duration, as the reactants can be conveniently mixed in darkness, while the film is being exposed.

11. Luminescence exposure apparatus for conducting luminescence reaction tests on specimens contained within a test well in a reaction test apparatus, comprising:
-
a lower housing having a flat, upwardly facing internal surface comprising means for receiving a piece of film thereupon, a mask covering the upwardly facing surface and having an opening therethrough positioned to correspond to the location of the test well in the reaction test apparatus, a biasing spring between the internal surface and the reaction test apparatus to resist the downward movement of the reaction test apparatus, when the reaction test apparatus is placed into the lower housing, and movable shutter means for controllably permitting light emitted from the test well to strike the film; an upper housing including translation means for controllably urging the reaction test apparatus downwardly against the resistance of the biasing spring, thereby contacting the bottom of the reaction well in the reaction test apparatus with the piece of film in the lower housing; and an extension on one end of the lower housing, the extension having an inclined surface on the bottom thereof comprising means to limit the angular rotation of the lower housing to a predetermined amount when the lower housing is placed onto a flat surface and rotated toward the inclined surface.
