Designed for applications that require evacuated apparatus to be filled with an inert gas to one atmosphere. Uses include the introduction of an inert gas into a vacuum desiccator or nitrogen into Airless-ware® apparatus. A pressure release valve should be placed between the nitrogen source and nitrogen manifold on all Airless-ware manifold installations.
Operation: Three mL of paraffin or silicone oil is added to the bubbler. One arm is connected to the low-pressure gas source, the other to the manifold or Airless-ware equipment. The check valve prevents oil or air from surging into the apparatus.
