A matrix mixing robot includes a plurality of precision pumps (such as precision syringe pumps), a distributor and a processor system. Each pump, under the control of the processor system, draws an associated stock solution from a stock solution source, and pumps the drawn stock solution out through an outlet. The distributor, also under the control of the processor system, directs a stock solution from a particular pump outlet to a selected solution receptacle. A multi-port distribution valve may be associated with each precision pump. Each valve, under control of the processor system, can connect its associated pump to one the pump's inlets or outlets.
