Harvard Apparatus Pump 33 DDS™ Dual Drive System Syringe Pump
The Harvard Apparatus Pump 33 DDS™ is a dual-drive syringe pump with two fully independent stepper motors enabling simultaneous bidirectional operation from 1.02 pl/min to 106 ml/min per channel. Purpose-built for push-pull microdialysis and dual-reagent experiments, it eliminates the need for two separate pumps while offering full independent programmability per channel.
What is the Harvard Apparatus Pump 33 DDS™?
The Harvard Apparatus Pump 33 DDS™ (Dual Drive System) is a uniquely engineered dual-channel syringe pump that provides two completely independent, synchronized drive mechanisms within a single compact housing. Unlike conventional dual-syringe pumps that share a single drive motor, the Pump 33 DDS allows each channel to operate independently with its own flow rate, volume target, and direction — enabling advanced infusion/withdrawal paradigms impossible with single-drive systems.
With flow rates spanning from 1.02 pl/min to 106 ml/min per channel and a 7" LCD touchscreen interface, the Pump 33 DDS is designed for demanding applications including push-pull microdialysis, dual-reagent mixing, gradient generation, and split-flow microfluidic experiments in both animal and cell-based research.
Key Features
- Truly Independent Dual Drive System: Each of the two channels has its own independent stepper motor and drive mechanism, allowing simultaneous infusion at different flow rates, independent withdrawal, or perfectly synchronized bidirectional operation.
- Ultra-Wide Flow Range: Delivers flow rates from 1.02 pl/min to 106 ml/min per channel, supporting ultra-precise microfluidic delivery through high-volume physiological perfusion in a single instrument.
- 7" Color LCD Touchscreen: Large, intuitive touchscreen with channel-by-channel control, enabling independent programming of each drive motor from one unified screen.
- Push-Pull Microdialysis Optimized: The independent dual drives are specifically suited for push-pull perfusion — infusing artificial CSF while simultaneously withdrawing dialysate at matched flow rates, eliminating the need for two separate pumps.
- Advanced Per-Channel Programming: Supports complex multi-step methods with ramps, I/O triggers, and gradient programming per channel, all storable on-device.
- Daisy-Chain Compatible: RS-485 interface supports multi-pump daisy chaining for integration with larger automated experimental systems.
