Beschreibung
Zusammenfassung:	A microfluidic device includes a microfluidic circuit having a main fluid channel and an inlet coupled to the main fluid channel for introducing fluid into the microfluidic circuit and at least one fluid chamber configuration. The fluid chamber configuration includes at least one fluid chamber, a fluid chamber inlet channel coupling the main fluid channel to an inlet of the fluid chamber, a fluid chamber outlet channel coupled to an outlet of the fluid chamber, a stop valve arranged in the main fluid channel downstream of the coupling with the fluid chamber inlet channel, where the stop valve blocks fluid at a pressure below a first burst pressure, and a flow restrictor in the fluid chamber outlet channel. The flow restrictor provides a back pressure higher than the first burst pressure of the pressure stop valve.
