Hydrogenator 3911, 3916 series

The 3911 and 3916 series manufactured by Parr Instrument Company, are hydro laboratory equipment that feature necessary valves and fittings for admitting hydrogen to the bottle. The materials to be processed in the device are sealed in a reaction bottle, with a catalyst and is connected to a hydrogen reservoir. Air is then removed through evacuating the bottle or by flushing with hydrogen. Moreover, pressure is then applied from the reservoir and the bottle is shaken to start the reaction.
