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
·Manufactured from 33 expansion, low extractable borosilicate glass conforming to USP Type I and ASTM E438, Type I, Class A requirements
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.
