A diagnostic device for measuring biochemical characteristics of microorganisms. A first chamber is provided into which is inoculated a test suspension containing an unknown organism. First passage means selectively provides liquid communication between the first chamber and a second chamber. The second chamber provides for contacting the liquid suspension with a substrate reagent which is located therein. Second passage means connects the second chamber to a third and selectively allows liquid communication therebetween. The third chamber may contain a suitable detection means for identifying the biochemical characteristics of the reacted test suspension when brought into contact therewith.

An improved diagnostic device comprising, a frame of substantially planar form having a transversely extending margin, which has a top surface into which are recessed a first well for containing a liquid test suspension, a second well for contacting the test specimen with a reagent and a third well for contacting the reacted test suspension with an indicator; wherein through the arrangement of the frame to a predetermined first spatial orientation a liquid communication between the first and second wells can be provided when the frame is rotated from its normal horizontal position about a first axis running parallel to a margin of the frame; and wherein further through the arrangement of the frame to a predetermined second spatial orientation a liquid communication between the second and third wells can be provided, said improvement comprising a first channel extending from the first well toward the transversely running margin of the frame providing for liquid communication between the first and second wells, said channel turning substantially parallel to the margin at its distal end to intersect the second well, the second well being transversely displaced from the first well; a second channel extending away from the margin substantially parallel to the first channel providing for liquid communication between the second and third wells, the second channel intersecting the third well, and the third well being substantially aligned with the second well; said wells and said channels between said wells being open to said top surface and a clear transparent film is provided in adhesive sealing contact with the top surface of the frame covering the wells, except the first well, whereby the first axis, about which the frame is rotated from its normal horizontal position in order to provide for liquid communication between the first and second wells, runs parallel to the transversely extending margin; and further providing for liquid communication between the second and third wells when the frame is rotated about a second axis, which is perpendicular to the top surface of the frame.
