The liquid storage apparatus 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 apparatus is intended for storing reagents to be used in an automatic blood analysing machine.
