  • Patent number: 9845499
    Abstract: A microfluidic device can have a plurality of microchambers connected to a microchannel via siphon apertures. The microfluidic device may be formed from a thermoplastic and capped by a thermoplastic thin film. The microfluidic device may be used for digital polymerase chain reactions by forcing reagent into the microchambers at low pressure via an inlet, forcing any gas trapped in the microfluidic device to outgas through the thin film by applying high pressure to the microfluidic device via inlets and outlets of the microfluidic device, and applying air at low pressure to the inlets in order to digitize the chambers such that the reagent in each chamber is isolated from the reagent in other chambers by an air gap. After digitization, the device may be used to run a digital polymerase chain reaction process.
