Abstract
An apparatus for reconstituting dried bacteria includes a first reservoir for the storage of reconstituting solution, a pump via which the reservoir is coupled to one of a pair of hollow needles arranged side by side in operative association with an apparatus for raising or lowering the pair so that in use they can be lowered to pierce a closure bung of a container in which bacteria are sealed under vacuum, the one needle being effectively longer than the other of the two hollow needles so that consequent upon lowering of the pair, the one needle passes through the bung before the other effectively shorter of the two needles. The shorter of the two needles is coupled to a second reservoir for the transfer thereto, in use of the apparatus, of reconstitution solution from the first reservoir together with bacteria from the container.
