Designed to be used with mineral oil or similar liquids to help monitor the flow of gas to organic reactions. Made with a 24/40 joint that can be used with flasks having a similar 24/40 joint. You will need approx. 10mL of oil to seal the lower inner tube. The tubing connection is 8mm O.D.

Used with mineral oil to observe gaseous addition to reactions. Also used to vent a reaction mixture to the atmosphere. Tube connections are 8mm O.D.

This bubbler is designed with an integral valve for controlling gas flow in reactions or to provide an inert atmosphere when either argon or nitrogen is used.

The inner tube is within 5mm of the bottom of the tube, require a minimal amount of mineral oil.
