The Harvard Apparatus Pump 33 DDS (Dual Drive System) is a leap forward in syringe pump capability. The Pump 33 DDS has two independent pumping channels controlled by an intuitive touch screen interface.
This multi-purpose syringe pump employs advanced syringe mechanisms that include a tight gripping, extremely secure syringe clamp that accommodates syringe sizes 0.5 µl to 60 ml. The Pump 33 DDS offers enhanced flow performance with high accuracy and smooth flow from 1.02 pl/min to 106 ml/min.
The new Harvard Apparatus Pump 33 DDS employs a graphical user interface controlled with a large 7” LCD Color Touchscreen.
Syringe tables containing all major syringe manufacturers allow simple selection of any compatible syringe size.
Audible Alarms, Adjustable Force and Screen Lock are all features that are available with the touch of the screen.

The bright informative display run screen presents the user with all key dispensing parameters in real time.
Three operating conditions are available to accommodate a wide range of setups and experimental protocols.
Independent Condition allows the Pump 33 DDS to operate as two separate syringe pumps named P1 & P2. P1 is syringe position 1, closest to the touch screen interface and P1 is syringe position 2 and is toward the backside of the unit. Each syringe will operate independently with different syringe types, size, force, target (volume or time) and flow rate settings. This innovative condition allows you to run two different flows at the same time using one instrument.
In reciprocating condition, both syringe channels move in opposite directions at the same rate using the same syringe size and type. When combined with a valve box, the reciprocating condition can provide the continuous fluidic delivery of a peristaltic pump with the accurate pulse free low flow rates provided by a syringe pump.
The Twin Condition allows both syringes to operate in the same mode using the exact same syringe type, syringe size, force, target (volume or time) and flow rate settings. The pump also allows the user to combine both flows for higher speed and volume infusion applications.
The Pump 33 DDS comes standard with USB and RS-232 for PC communication and RS-485 for pump-to-pump communication. An entire suite of ASCII commands is available to control the pump remotely with a PC. The pump contains a footswitch input and digital input/output for each independent pumping channel.
A full range of accessories are compatible with the Pump 33 DDS (Dual Drive System) Syringe Pump including syringes, connectors, tubing and valve boxes.
