I am a french student who's discovering microfluidic through english texts and I am not sure to understand waht is a backpressure in this case? Is this a pressure given by the operator or induced by the device??

Thank you for your answers!

Hi frenchero! Bienvenue PF!

Backpressure is an effect of the structure of the device

see http://en.wikipedia.org/wiki/Backpressure for some details.

In a microfluidic context, backpressure typically means the pressure that one needs to exert on a syringe (or alternatively, that a pump needs to apply to tubing) to maintain a certain flow rate. This matches the general description in the Wikipedia article.
