Patent number: 4170861Abstract: A method and apparatus for filling petri dishes include the features of situating a stack of empty petri dishes at a dish-drop station where the stack rests with the lowermost petri dish of the stack on a stationary support. A moving structure engages this lowermost petri dish and moves it beyond the stationary support to a filling station, and during this movement of this lowermost petri dish to the filling station a lower dish member of the petri dish drops down from an upper lid member thereof and remains spaced beneath the upper lid member while being supported by a movable support which carries the lower dish member to the filling station. At the filling station a nozzle of a pump becomes situated in the space between the upper lid member and the lower dish member of the petri dish and fills a given quantity of agar into the lower dish member, whereupon this latter member and the upper lid member spaced thereover are moved to an elevating station.Type: GrantFiled: April 7, 1978Date of Patent: October 16, 1979Assignee: New Brunswick Scientific Co., Inc.Inventors: Philip Snyder, David Freedman
