Abstract

Disclosed is a microfluidic device comprising at least one micro-aliquotter for dispensing fixed or variable volumes. The micro-aliquotter includes an rigid, dimensionally stable foundational layer having a fluid port therein that is in fluid communication with a channel within the microfluidic device, and an elastic film positioned on the foundational layer where the film covers the fluid port. The elastic film is sealed to the foundational layer so fluids entering through the fluid port can be captured between the elastic film and the foundational layer. The elastic film being expandable from a rest position on the foundational layer to a dispensing, or aliquotting, position in which an aliquot volume of a fluid is contained between the film and the foundational layer.
