ABSTRACT:
An injection system for use with a luminometer, which includes a carrier movable between a liquid loading station and a liquid dispensing station and a dispenser assembly mounted on the carrier and including an injector needle arranged, when at the liquid loading station, to pass through an aperture in a part of the luminometer aligned with a test sample container therein, the container being in a test chamber with which a photomultiplier device communicates. The system also includes a sealing arrangement which prevents light from passing through the aperture in the luminometer, both when the needle extends through the aperture and when the needle has been withdrawn from the aperture.
