Automated testing system

An automated testing system for the quality testing of production samples of a blood-clot dissolving product having (a) a frame structure having a horizontally disposed support surface; (b) a loading station for the placement of test tubes into a test tube rack; (c) a cooled pipetting station for automated dispensing and mixing of reagents and production samples; (d) a heated bead-drop station for simultaneous addition of a timing bead to each test tube, having a timer for measuring the time to completion of blood-clot dissolution by detecting the movement of each bead to the bottom of each test tube; (e) a robotic apparatus having an arm and pick-up and release device at the end thereof which is movable both vertically and horizontally and is adapted to move said test tube rack and tubes between said stations; and a programmable computer for controlling said dispensing, mixing and moving operations and recording the results of the product being tested.
