For most microfluidic experiments, external systems to actively move liquids are needed. Depending on
the application, different methods to actuate the fluids are available. In principle, one can differentiate
between pumps and pressure controllers. Pumps such as syringe or peristaltic pumps shown in the
following pages generate a constant flow rate while pressure generators generate a constant pressure
by pressurizing a reservoir which is connected to the microfluidic device. We have selected a range of
instruments to be able to offer the best solution for a given application.
