Advantages of pressure based Microfluidic

In microfluidics, different types of flow delivery are used starting from the capillary forces, passing from the mechanical pumping and terminating by the new innovative techniques for fluid actuation such as the patented Fastab and LineUp.

In this section, you will have access to all the information regarding the Microfluidic Stability and Responsiveness of the pressure based microfluidic and to a comparison between multiples flow control technologies on the market.

The pressure driven flow for microfluidic applications has multiple extended capabilities. It’s possible to enumerate cell perfusion and shear stress, stable flow for droplet generation, cost-effective solution for sequential injection in cell perfusion applications and so on.

All of these and others are detailed in this section. Read More »

In microfluidic instrumentation, stability refers to the ability of an instrument to maintain a certain physical property at a constant value, while rejecting any perturbations in the environment. It is a very important parameter, as even small variations in physical quantities during microfluidic experiments can dramatically change the results. A stable instrument ensures that results are repeatable and reproducible.

Droplet production using microfluidic systems was implemented for applications where monodispersity is of high importance. Flow rate stability is critical for having repeatable reactor volume and reproducible results. Syringe pumps are commonly used for generating droplets in microfluidic experiments but can show limited flow control. Pressure-based flow controllers show high-precision flow control, high reaction time, and flow monitoring is possible.

According to the Computer Science and Communication Dictionary, responsiveness refers to the specific ability of a system of functional units to complete assigned tasks within a given time. In the case of microfluidics, we define responsiveness as the time it takes for the pressure or the flow-rate in the fluidic reservoir to reach a given set point.
