A lab I support in Aero Astro needed a way to drop a single drop of oxidizer onto a test watch glass with drop of fuel in it. They record the reaction with a high speed camera. The challenge here is that the oxidizer is; corrosive, toxic, explosive and boils at room temperature. Working with the Purdue chemistry glass blower (Thank you Bob Gorman) this device was designed and made. The teflon rod in the center releases a single drop of the condensed liquid from the very bottom by turning the knob at the top, the whole device is water jacketed for cooling and safety. The apparatus was successful on its first deployment and has allowed the lab to take data previously unavailable. Its compact combination of continuous addition funnel and condenser.
