Abstract: A photometer assembly consisting of a basic photometer unit having a photomultiplier tube projecting from its top wall. A reaction chamber is mounted over and receives the photomultiplier tube. The reaction chamber includes a stationary spool-shaped member having a shank consisting of a shell portion which surrounds the photomultiplier tube and is provided with an exposure aperture. A sample tube carrier rotatably surrounds the shank and has a vertical socket receiving a transparent sample tube, the carrier having a light duct leading from the socket to the shell portion, the duct being movable into registry with the exposure aperture so as to expose the sample tube to the photomultiplier tube in a unique position of the carrier, the sample tube being shielded from ambient light by the spool-shaped member and carrier in this position. The top of the spool-shaped member has a vertical guide tube, the guide tube registering vertically with the sample tube when the sample tube is in said unique position. Luminescence-inducing reagent or radiation may be injected into the sample tube through said guide tube, and the resulting luminescence may then be measured by the resultant signal generated by the photomultiplier tube. The top of the spool-shaped member is cut away opposite the guide tube to allow the sample tube to be inserted into and withdrawn from the socket.

Abstract: A flow cell assembly for adapting an apparatus for both fluorometric and colorimetric studies. The assembly includes a holder having a folded optical path between an external light source and photosensitive response means. The light input to the optical path is at right angles to the light output therefrom so that the assembly may be employed in place of the sample cuvette of a conventional spectrofluorescence measuring instrument. The holder contains a flow tube having an offset sight passageway portion supported endwise in the optical path. The holder includes a light shield plate slotted to receive the legs of the offset portion and to substantially protect the offset sight passageway portion and the folded optical path from stray light. The flow tube may include an integral debubbler.
