Abstract (en)
An example system includes a passive dampener device having a chamber to hold a fluid. The passive dampener device is fluidically coupleable to a pump and a microfluidic device. The chamber has an air headspace to dampen pressure waves created by the pump in a sample fluid flow through the microfluidic device.
