The pump can infuse simultaneously at different rates, or infuse with one syringe and withdraw with the other. When combined with a valve box, the Model 88 can provide continuous delivery.

The Gemini 88 is designed for continuous operation 24/7 with a range of syringes from 0.5 µl up to 140 ml.

The pump has high pressure capabilities and TTL and RS-232 interfaces for data acquisition and control. The communications ports enable daisy-chaining up to 100 pumps.
