Abstract
This invention is a debubbler, degasser or gasser device used to remove gas bubbles and/or dissolved gasses from a liquid stream or to add gasses to a liquid stream. The device consists of a first block, a hydrophobic membrane, and a second block. The first block has a channel for carrying liquids which is grooved into its lower surface. The end of the channel is connected to an inlet and outlet. The second block has venting holes. When the hydrophobic membrane is pressed between the first and second block liquid can flow through the channel and bubbles or dissolved gasses in the liquid stream pass through the hydrophobic membrane. Alternatively, or in combination with degassing or debubbling, the device may be employed to introduce into the liquid stream gasses provided on the opposing side of the hydrophobic membrane.
