Abstract
A luminescence measuring system comprises an apparatus for supplying samples located in separate test tubes. In the measuring chamber of a luminometer, the samples are in turn presented to a light detector, such as photomultiplier. Two mutually displaceable components, which are cup-shaped and fit into one another with the cup bottoms facing outwards, define the measuring chamber. The component shells are provided with holes which can be aligned by relative displacement of the components so as to admit the test tube into the luminometer and the measuring chamber and subsequently to discharge it therefrom under the action of gravity. The test tubes are conveyed to the luminometer by a sleeve-chain conveyor having a bottom with a through hole.
Claims16
A luminescence measuring system comprising:
- a conveyor for delivering containers of samples for luminescence measurements, including a translationally drivable chain of vertically disposed tubular sleeves, each sleeve for carrying a container, and a fixed bottom provided with a hole, said chain of sleeves being displaceable relative to the bottom above the hole to align the tubular sleeves with the hole so that a container exits an aligned tubular sleeve through said hole under the action of gravity;
- and
- a luminometer disposed below the bottom of the conveyor to receive the containers from the conveyor through the hole, the luminometer comprising two cup-shaped components, each having at least a peripheral shell and a base side, the components being relatively displaceable and disposed so that the peripheral shells mutually engage, an interior measuring chamber in one of the components being enclosed by the shells and outer facing base sides;
- wherein each shell has an admission hole and an exit hole communicating with the measuring chamber, the components having a first relative position wherein the admission holes are positioned vertically above the measuring chamber and aligned with the hole in the bottom of the conveyor, and a second relative position wherein the exit holes are aligned in a position vertically below the measuring chamber;
- and
- wherein alignment of the admission holes and the hole in the bottom allows a container to move from the conveyor into the measuring chamber by action of gravity and alignment of the exit holes allows the container to exit the measuring chamber by action of gravity.
A luminometer device comprising:
- a luminometer comprising two cup-shaped components, each having at least a shell and a base side, the components being relatively displaceable and disposed so that the shells engage so that an interior measuring chamber in one of the components is enclosed by the shells and by the base sides;
- wherein each shell has an admission hole and an exit hole communicating with the measuring chamber, the components having a first relative position wherein the admission holes are aligned vertically above the measuring chamber, and a second relative position wherein the exit holes are aligned in a position vertically below the measuring chamber;
- and
- wherein alignment of the admission holes allows a container to move from a position above the admission holes into the measuring chamber by action of gravity and alignment of the exit holes allows the container to exit the measuring chamber by action of gravity,
