UMP3 includes the pump head only. For controller information, see Micro4.
Nanoliter volumes
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 Fluids injected or withdrawn are held entirely within the micro syringe to maintain a low fluid dead volume in the micropump.
Positioning
For positioning, the UltraMicroPump III may be attached to any of several WPI micropositioners such as the M3301 (manual), DC3001 (motorized), or any manual stereotaxic manipulator.
Smart Controller
An Integral component in the UMPIII system is a microprocessor-based controller, 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 display. From the keypad you 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- enter the volume to be infused or withdrawn, rate of delivery, and syringe type
- synchronize the starting and stopping of any combination of syringe pumps
User parameters can be stored in the controller's "non-volatile" memory for instant recall when the unit is powered on. An optional footswitch can be plugged into a connector on the rear of the controller for "hands free" start/stop operation.
Computer Control
An RS-232 port on the rear of the controller can be used to connect it to a computer for use with computer control programs.
