Hydrogenator - 1 000 - 2 000 ml | 3921, 3926 series
The 3921 and 3926 series by Parr Instrument Company is a Hydrogenator which serves as a hydrogen reservoir. In the prior process, the Air is removed either by evacuating the bottle or by flushing with hydrogen. Then a pressure is applied to the reservoir and it is shaken vigorously to come up with a reaction. When the certain reaction is attained, the shaker will stop and the catalyst is recovered.
