A high capacity microarrayer for spotting solution onto slides in an automated microarray dispensing device. A microplate indexing device automatically moves, in sequence, a plurality of microplates to a solution removal area. A dispense head accesses each microplate at the solution removal area to remove solution from the microplate. The dispense head then moves to a slide positioning station to spot slides at the slide positioning station. In a preferred embodiment of the present invention, the microplate indexing station has at least one input stacking chamber for stacking microplates, and at least one output stacking chamber for stacking microplates. A walking beam indexer is disposed between the at least one input stacking chamber and the at least one output stacking chamber. The walking beam indexer is for moving microplates from said at least one input stacking chamber to said at least one output stacking chamber. While at the solution removal area, a lid lifter lifts the lid off each microplate to permit the microplate to be accessed by the dispense head for solution removal. After the solution is removed, the lid lifter replaces the lid. In another preferred embodiment, there is at least one light source capable of illuminating the slides, and at least one camera operating in conjunction with the at least one light source. The at least one camera is capable of acquiring and transmitting slide image data to a computer. The computer is programmed to receive the slide image and analyze it. The computer will then generate post analysis data based on the analysis of the slide image data. The post analysis data is available for improving the spotting of the solution onto the slides. In a preferred embodiment, the slide image data includes information relating to slide alignment, information relating to spot quality, and slide identification information. In a preferred embodiment, the analysis of the information relating to slide alignment enables the computer to make automatic adjustments to the relative positions of the at least one dispense head and the slides to increase the accuracy of the spotting. In a preferred embodiment, the analysis of the information relating to spot quality identifies a spot as pass or fail. An operator is then able to rework the spot. In a preferred embodiment, the analysis of the slide identification information enables the computer to track each slide.

The invention is directed to a device for dispensing and observing the luminescence of individual specimens in multi-specimen arrangements, particularly for the examination of biological, chemical or cytobiological assays with high specimen throughput. It is the object of the invention to find a novel possibility for dispensing in multi-specimen arrangements (microplates) and for observing the luminescence of the individual specimens, particularly for examining biological assays with high specimen throughput, which permits an immediate observation of the course of luminescence while dispensing proceeds at the same time without being limited to a determined type of microplate. This object is met, according to the invention, in that the dispensing unit has at least one linear dispensing comb containing an even number of dispensing nozzles representing an integral divisor of the number of wells along one dimension of the microplate, the dispensing combs are arranged so as to be displaceable orthogonal to their longitudinal dimension, every dispensing comb is connected to a controllable pump for metering the amount of liquid to be dispensed without immersion in the wells of the microplate, and the CCD camera is oriented by a fast optical system to a large-area rectangular region of the underside of the microplate across from the dispensing unit, the surface being adapted to the dimension of the dispensing comb and to the area of the microplate covered by the dispensing comb, so that the elapsed time for the luminescence is measurable simultaneously while dispensing continues.

The subject of the present invention is a transfer device for analysis equipment, which transfer device comprises a track consisting of, inter alia, guide and support rails on which to transfer a pit plate on a transport cassette along the track. The transport cassette includes a traction rail parallel to the guide and support rails. Traction units are fitted onto the track in the transfer device as means operative jointly with said traction rail to move the transport cassette. In order to control the operation of the traction units, the traction rail is provided with sign codes readable by means of an optical reading device. This indicates the position of the cassette relative to the optical reading device so that the transport cassette may be stopped to position the desired line of pits, transverse to the track for operations to be performed in the analysis equipment, such as liquid dosage, photometric measurement operations, etc.
