    Abstract: A fluidic device and a method for degassing a fluidic device are presented. The fluidic device includes a plurality of fluidic components such as channels, chambers, and integrated valves and pumps, etc. A porous membrane is disposed on a degassing area of the fluidic device for removing gas (such as, for example, bubbles) contained in a liquid. A fluid control device monitors a pressure profile indicating a pressure in the fluidic device over time and applies a pressure differential between two sides of the membrane when activated. The membrane is permeable to gas in the fluidic device and is impermeable to liquids through the pores under the pressure differential. The disclosed method enables degassing large volume of gas at a high flow rate and provides a bubble free filling in a fluidic device which is critical to precision sample metering, mixing, fluid control, reaction, and detection, etc.

    IPC: B01L3/00

    Abstract: A microfluidic product pouch assembly may be used in a microfluidic chip. The microfluidic product pouch may include a pouch surrounding an inner chamber and having a rupturing portion and an inner membrane positioned within the inner chamber. The inner membrane may separate the inner chamber into a first cavity and a second cavity. A reagent may be positioned within the first cavity and/or the second cavity. The microfluidic product pouch assembly may also include a rupturing structure. The rupturing structure may be configured to selectively break the rupturing portion of the microfluidic product pouch.
