ABSTRACT:
An apparatus for electrophoresing a sample and for thereafter either scanning in the visible mode or the fluorescent mode, under control of a central processor, to provide scanning densitometry of the electrophoresed sample, and with the fluorescent mode scanning being performed in situ. The apparatus includes a gantry which moves from left to right in the XY plane. The gantry draws, delivers and deposits the samples and reagents, and includes safety devices to prevent the gantry from movement and damage when there are obstructions in the path of the gantry. A fluorescent scanning unit is moved by X- and Y-direction motors to position a photomultiplier over an electrophoresed sample. In this way, the electrophoretic sample can remain fixed in place during sample delivery, ultraviolet exposure and measurement operations.
