WPI Ultra Microinjection Syringe Pump

With its digital controller, UltraMicroPump III can dispense as little as 600 picoliters per incremental advance of the syringe piston (using a 0.5μL syringe). Syringes may be filled externally and then inserted into the pump or filled while mounted in the pump. Fluids injected or withdrawn are held entirely within the micro syringe to maintain a low fluid dead volume in the micropump.
