An improved luminometer is provided which uses a top loading plate carrier which receives a microtitration plate and uses a mask having an aperture corresponding to each test cell in the plate carrier. When the mask rotates downwardly to cover the microtitration plate, the plate carrier automatically orients the microtitration plate in the X, Y and Z directions. Reagents are added to the individual test cells through the mask aperture. Each reagent injector is extendable and retractable so that liquids can be added below the mask aperture during purging or washing and then the injector retracted. A pump is provided for each injector which is driven by a stepper motor and a rack and pinion connection to a syringe.
