An enclosed chamber is used in a system for screening of a liquid specimen through binding assays. The enclosed chamber includes an inlet, an outlet, and a plurality of discrete reactant containing wells communicated by a common reagent flow path between the inlet and the outlet. A transparent member or coverslip defines on an inside thereof the plurality of wells. Each well has a bottom for receiving an allergent/antigen/reactant, which emits light upon reacting. The coverslip can optionally define at least one lens at each well. A bottom encloses the plurality of wells and defines between the inlet and the outlet a common reagent flow path between the inlet and the outlet. This bottom defines for each of the plurality of wells a flow-diverting member. An opaque partition is disclosed for surrounding the individual lenses and generally isolating the light path from each well.

An apparatus and method for cleaning containers, such as sample containers for environmental testing, involves providing modular cleaning bays into which an array of inverted containers can be transported, such as by means of a drive chain. Independently operable nozzle banks disposed in the cleaning bay generally below the resident container tray are driven in an x-axis motion, such as by a stepper motor, to register a selected nozzle bank with successive rows of containers within the tray. At each row of containers the nozzle bank, which is selected in accordance with the size and spacing of the containers being processed, is caused to travel in a z-axis motion through a process cycle in which the nozzle elements of the nozzle bank traverse through the open mouth ends of the containers registered therewith and in which a fluid stream is projected directly onto the interior surfaces of the containers, preferably sweeping the entirety of those surfaces. The tray of containers is exited from the cleaning bay after the last row of containers in the tray is processed. Modular cleaning bays can be cascaded together for processing trays of containers through different washing and rinsing solutions, and for air drying the interior surfaces of the containers.
