With its digital controller, UltraMicroPump III can dispense as little as 600 picolitres 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 Fluids injected or withdrawn are held entirely within the micro syringe to maintain a low fluid dead volume.

Features:

• Versatile injector uses microsyringes to deliver picolitre volumes
• Syringes are easily installed, just snap the barrel into the clamps
• Threaded shaft drives syringe plunger allowing smooth and accurate movement

An integral component in the UMPIII system is a microprocessor-based controller, SYS-MICRO4, which provides an "intelligent" and easy-to-use interface to up to four syringe pumps. Operating parameters are set with the membrane keypad and LCD. From the keypad the user can select the following functions: set pump to infusion or withdrawal mode, enter the volume to be infused or withdrawn, rate of delivery, and syringe type as well as synchronise starting and stopping of any combination of syringe pumps.
