Delivering apparatus

In an improved apparatus comprising a delivery device including a single probe and being operative to suck at least one kind of liquid such as a plurality of reagents, samples or the like, from respective vessels into the probe and deliver the liquid thus sucked from the same probe into reaction vessels, the improvement comprises:

• providing said probe to be movable along a given moving path, said vessels containing said liquids to be delivered being fixedly arranged at a plurality of predetermined sucking positions along the moving path of said probe and in which said reaction vessels are movable along a path which is crossed with the moving path of said probe at a discharging position, and in which provision is made of means for locating said probe at any sucking position to suck a given amount of liquid contained in the vessel situated at the relevant sucking position and then moving the probe into said discharging position to discharge the sucked liquid into a reaction vessel situated at the discharging position.
