Abstract
The apparatus comprises a turntable carrying, in a circular array centered on a central rotational axis of the turntable, a plurality of vials extending below the underside of the turntable. A stepper motor imparts stepwise rotational motion to the turntable so that during dwell periods of the turntable, specimens in the vials can be investigated optically. Air in a space below the turntable and bounded laterally and at the bottom by an enclosure is circulated by a rotating vane, and a thermistor, responsive to the temperature in the region of the vials, controls a heater in the space below the turntable so as to maintain the temperature of the vials substantially at a predetermined value. In order to dispense liquids into the vessels at predetermined temperatures, the apparatus additionally includes a liquid dispenser mounted adjacent the turntable and comprising a tubular body with an electric heating coil and a dispensing device which dispenses liquid from the outlet of the tubular body in predetermined quantities, the heating coil being supplied with the necessary quantity of power to maintain the temperature of the dispensed liquid substantially at a predetermined value. Preferably, the apparatus is used for analysing blood specimens.
