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.

Abstract: The liquid storage device comprises a rotary heat-insulated jacket mounted on a stationary base to rotate about a vertical axis. The jacket is formed to carry a plurality of inverted liquid containing vials, situated at least partially within the jacket, the vials being in communication with respective take-off cups which are arranged near the base of the jacket and around the periphery thereof and from which liquid specimens can be drawn off. A constant level device ensures that the level of liquid in the cups is kept at a substantially constant level. The jacket is provided with a stepping drive so that it can be stepped about its rotary axis to bring any selected cup into a liquid take-off position.The interior of the jacket is cooled with circulating, cold air and the temperature of the vials is kept at a predetermined value, below ambient, by an air heater.The storage device is intended for storing reagents to be used in an automatic blood analyzing machine.
