HIGH THROUGHPUT DISPENSING OF FLUIDS

摘要

This invention provides an apparatus and method for dispensing fluidic materials involving the employment of a hydrophilic capillary (24) dimensioned for drawing a liquid therein in a volume less than about 10 microliters; a hydrophobic medium (26) sealingly adjoining said capillary (24) and defining an interface (22) therewith for resisting flow of the liquid into the capillary beyond the interface; and a source of a pressure pulse for ejecting fluids drawn into the capillary (24).
