Harvard - Model 33 DDS -Dual Drive Syringe Pump System

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 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.

This new syringe pump employs a graphical user interface controlled with a large 7” LCD color touch screen for quick and easy syringe pump setup. 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.
