ABSTRACT:
Dispenser apparatus for simultaneously providing predetermined equal volumes of liquid to each of a plurality of wells. The apparatus includes a disposable multiple chamber dispenser module having a top surface and a plurality of dependent walls each defining a lower chamber for alignment with a corresponding well. Each chamber has an open lower nozzle end and extends upwardly to an opening in the top surface. A die plate having a plurality of concavities is provided with each concavity having an equal volume and a mouth. Each concavity is defined by an inner surface and corresponds to one of the chambers. The apparatus further comprises diaphragm means having a portion extending across the mouth of each concavity. Each diaphragm portion is movable from a first position across the mouth of its concavity to a second position in surface contact with the inner surface defining that concavity. Additionally, the apparatus includes means spacing the diaphragm means from the module top surface and forming upper chamber means which constitutes an upper extension of each lower chamber. Each upper chamber means has a volume that is variable by the position of the diaphragm portion. Finally, the apparatus comprises means for selectively moving each diaphragm portion from a first position to a second position.
