Bring the Sealed Field Testing Kit to Apothecary Zinge in the Undercity.
"Here you go, the power source is safely removed and the data is preserved. Well, safe journeys and all that. Hope the nefarious science experiment worked out for you and all."
The goblin turns away from you to attend to the demands of the Gadgetzan Water Company. You secure the sealed testing kit for the journey back to the Undercity. Apothecary Zinge waits for you and the Sealed Field Testing Kit there.
