ABSTRACT:
A method for handling and dispensing small volumes of liquid, and apparatus for carrying out the method, are disclosed. A small volume of liquid, which is retained within a fluid-dispensing member, is dispensed therefrom by accelerating, and then abruptly decelerating, the member. The abrupt deceleration causes the retained liquid to discharge. The discharged liquid may be directed toward a receiver. A micro volume liquid dispenser for practicing the method includes a plurality of fluid-dispensing members configured for aspiring and retaining a small liquid volume via capillary action. The dispenser further includes an actuator for moving/accelerating the fluid-dispensing members and for stopping/abruptly decelerating the fluid-dispensing members.
