Microfluid channel system with bubble catcher device and method for the removal of gas bubbles

摘要

It is a microfluidic channel system to a bubble catcher device is provided, wherein the bubble catcher device at least one for gas is essentially impermeable for liquids and substantially permeable semi-permeable membrane (11) comprises. The semipermeable membrane (11) is adjacent a feed channel (21) for liquids and an outlet channel (22) for liquids from one another, whereby in the region of the feed channel (21) mounted on the semi-permeable membrane (11), a bubble trap chamber (10) is provided. The bubble trap chamber (10) is provided with a positive pressure. Furthermore, from the bubble trap chamber (10) is a bubbles outlet channel (41) for discharging of gas bubbles from.
