The Gemini 88 Plus dual-rate syringe pump (photo) provides two independent pumping channels linked through hardware and software, combining two individual syringe pumps into one instrument. The syringe pump can infuse simultaneously at different rates, or infuse with one syringe and withdraw with the other. When combined with a valve box, it provides the continuous delivery of a peristaltic or piston pump with the accuracy, absence of pulsation and low flowrates of a syringe pump. This functionality allows continuous infusion or withdrawal, with both high- and low-pressure operation possible. The system is compatible with a wide variety of syringes. — KD Scientific, Holliston, Mass.
