Abstract
A luminometer comprises a body which is formed with a bore for receiving a sample container and a cavity communicating with the lower end of the bore. A control device having a part-circumferential ramp is rotatable within the cavity for displacing the sample container along the bore to and from a test position in which the sample container is exposed to a photo-multiplier device. The control device is rotated by a cap which is coupled to the control device and which covers the upper end of the bore in light-tight manner as the control device lowers the sample container to the test position.
