Abstract
A workstation that provides an efficient method to collect biological tissues in a column tissue array format from blocks of embedded, frozen tissues, or fresh tissues. The workstation has a control unit for directing operations of the workstation and the operation unit for performing the production of the tissue column array. The operation unit comprises an array of vertical tubes in a platform, an arbor which engages and presses down the designated tube in the array, the embedded tissue block which is mounted directly below the designated tube, assemblies of motors responsive to the control unit for driving the platform and the tissue block, a light source block for generating an alignment signal, and a light detector block which measures the signal from the light source to determine the degree of alignment between the arbor, punch tubes, and the specimen block.
