Abstract

The present disclosure is drawn to microfluidic devices. In one example, a microfluidic device can include a microfluidic channel. A vent chamber can be in fluid communication with the microfluidic channel. A capillary break can be located between the microfluidic channel and the vent chamber. The capillary break can include a tapered portion and a narrowed opening with a smaller width than a width of the microfluidic channel. A vent port can vent gas from the vent chamber. The vent port can be located a distance away from the capillary break so that a fluid in the capillary break does not escape through the vent port.
