At just 4.75" x 4.5" and 2.1 lbs., the PSD/3 is the smallest and lightest Hamilton syringe pump. The PSD/3 also offers the slowest and smoothest flow rates thanks to its pulseless Servo motor. This pump is capable of dispensing a single stroke over 60 minutes as a standard feature, although longer single stroke dispensing times are possible through customization. This feature is especially useful in applications where careful, minute liquid delivery is vital.
The PSD/3 performs all standard liquid handling functions, including dispensing, serial dispensing and diluting. It is the only half-height pump with an easy, push button valve exchange. Also, the PSD/3 is the only syringe pump that is mostly enclosed and can be flush mounted.
Best for microfluidics
Microfluidics requires pumps to maintain the precise control and manipulation of fluids that are often geometrically constrained to a small scale flow path. While the PSD/4 performs proficiently in this capacity, the PSD/3 is the best choice.
The PSD/3 comes with two exclusive Hamilton advancements—smooth flow and true speed firmware. Smooth flow firmware ensures a steady stream of liquid with no surges and little to no pulsing. This firmware creates a very consistent flow rate particularly beneficial to those using microfluidic chips to perform a variety of reactions.
The pump’s true speed firmware guarantees it functions at the speed you set it to with no variation. This benefit is especially critical for applications where a precise flow rate is critical.
