Basic setup using using pressure regulators for microfluidics

Example : Using a high precision pressure regulator to generate droplets in microfluidic chips

Droplets in microfluidic devices are generally generated with a syringe pump. In this case droplets take time to get a stable size and oscillate with the flow rate and the compliance of the material used.

When the flow rate is controlled using a pressure regulator those problems disappear since high precision pressure regulators do not oscillate and react within seconds.

The syringe pump is a convenient solution for fluid handling since pressure regulators need to be plugged to a pressure source to be functional.  In order to overcome this problem, Elveflow® proposes a high precision pressure regulator integrating a pressure source which allows controlling flow in microfluidic devices with a precision of 100µbar and only requires an electric plug.

Why  do pressure regulators not generate flow oscillations?

When using a syringe pump, droplets oscillate in volume and speed since the “step by step motor” of the syringe pump produces vibrations which are transmitted to the flow through the translation of the syringe piston. The pressure generated by our integrated rotary pump is smoothed by our pressure regulator and low bandwidth filter leading to a flow rate without any oscillation.
