How to choose the right microfluidic flow control system?

Microfluidic flow control systems: Syringe pumps

Syringe pumps are the most commonly used flow control systems in microfluidics even if in the last 5 years researchers have begun to use more alternative flow control systems (see our study on researchers&#; opinions about microfluidics flow control).

Let&#;s say that syringe pumps can be divided in two categories. Classic syringe pumps, which are quite inexpensive but generate flow oscillations when dealing with microfluidics, and pulseless microfluidic syringe pumps, which are quite expensive but clearly offer better performances in terms of flow stability. In this tutorial, we will focus only on pulseless microfluidic syringe pumps. If you decide to use common syringe pumps, the information we provide in this tutorial will apply, but keep in mind the fact that your flow will not be stable at low flow rates.

The main advantage of syringes is that they are quite easy to use. The main weak point of pulseless syringe pumps is their low responsiveness, since it depends on the microfluidic setup. Flow changes inside chips can take seconds to hours (see our tutorial on syringe pump responsiveness in microfluidics). This lack of reactivity is one of the main limitations of syringe pumps for numerous applications. However, in and , new solutions can help to overcome these problems (see our tutorial on how to upgrade your syringe pump to fit it to microfluidic needs).
