Described here is a mechanical and electronic device which can accurately draw up and dispense a volume of fluid. A novel syringe is described which can replace (and overcome some of the shortfalls) of the traditional mechanical syringe by way of a liquid syringe. The syringe system is designed to be used in conjunction with modern liquid handling systems used in biological and biochemical research as related to drug screening. However, the syringe system is not limited to such applications. Also of key importance to this invention, is the use of a monitoring system to accurately monitor and record the actual volumes being drawn up and dispensed. The liquid piston has the advantage of reduced friction and removes the necessity for there to be any o-ring or sealing system which requires periodic replacement and/or maintenance.
