Abstract: Aspects of the present invention relate to laboratory systems for processing tissue samples and specimens within a laboratory. In particular, the present invention relates to a system for automating sample processing, comprising handling and analysis of tissue specimens with laboratory and/or medical diagnostic equipment. In one form the present invention relates to a method and apparatus for sample processing tissue specimens for histological and/or pathological laboratory analysis involving procedures or tasks such as, for example, tissue processing, embedding, staining, coverslipping and imaging. In a laboratory system utilizing aspects of the present invention there is provided at least one workcell and at least one conveyer in which tissue samples may be routed.

Abstract: A coverslip pick-up and transfer head comprises a pair of spaced suction cups which are angled downwardly and outwardly. A spring loaded plunger in an extended condition extends below the suction cups such that when a coverslip is help by the suction cups it is flexed in a concave shape. A solenoid, when energized, retracts the plunger against the spring force. In use a coverslip magazine containing a stack of coverslips is raised under the head causing the plunger to retract until the suction cups contact the coverslips. Vacuum is applied to the suction cups and the magazine lowered whereby the coverslip is held by the suction cups and flexed into a concave shape. The solenoid is energized momentarily causing the plunger the retract and extend thereby delivering a gentle flexural pulse to the coverslip causing any further coverslip adhered to the underside of the top coverslip to be released and returned to the magazine.
