Apparatus and method for luminescent determination of concentration of

Apparatus for testing at least one liquid sample, by immersion therein of a probe for coaction between said probe and sample, having a reloadable sample carrier for at least one sample container; a reloadable probe carrier for at least one probe; a frame having locating means for relatively locating the sample carrier and the probe carrier laterally in the frame, parallel motion means for guiding the probe longitudinally into the sample container and stop means for locating the probe at a predetermined distance into the sample container, locking means preventing the probe from being withdrawn more than a predetermined distance in the outward direction from the sample container, timing and control means for releasing said locking means after a predetermined time, and self acting withdrawal means for withdrawing the probe and probe carrier to a position clear of the sample container; the said sample carrier and probe carrier being arranged so as to be severally removable away from the said frame.

Apparatus for testing a liquid sample

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.
