ABSTRACT:
An automated metered fluid dispensing and aspirating apparatus comprising a combination delivery/removal fluid head with upper shuttle and lower reservoir assemblies is disclosed. A covered, variably positionable well table allows for mounting sample wells and automatically presenting at least one array of sample or reaction wells to the delivery/removal fluid head at a time. A fluid handling system of inter-connected tubing, pumps and valves interfaces with the delivery/removal fluid head. The fluid handling system provides reagents to and removes waste from the delivery/removal fluid head and sample wells. A control assembly, including a central processing unit and hardware, software and gas pressure sources, provides for time responsive operation and control of the delivery/removal fluid head, drive mechanisms for the table and fluid head, fluid handling system and well table. The entire apparatus is mounted on its own platform and includes separate housings for control and sample handling sections.
