Hi!
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 á 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.
