A rehydrator which dispenses precise amounts of liquid to each row of wells in a titration tray where the dispensing of the liquid is performed through valving means in timed relation to indexing of the platform to present a row of wells beneath the dispensing orifices. The indexing of the tray and the valving means are accomplished by the same drive means to obtain the timed relation.

A rehydrator for rehydrating material in spaced apart wells aligned in columns and rows in a titration tray, comprising means defining a plurality of spaced apart and aligned orifices, a tray platform movable beneath said orifice defining means between two reference positions so as to sequentially present a row of wells beneath said row of orifices, a liquid reservoir defining means coupled to said orifice defining means, means applying a constant pressure to said liquid in said reservoir, valve means connecting said reservoir defining means to said orifice defining means, valve actuating means, indexing means for incrementally indexing said platform, and drive means coupled to said indexing means and said valve actuating means to first index said platform a distance between the rows of wells of said tray and then to operate said valve actuating means to dispense a controlled volume of liquid under the constant pressure.
