Parr 3921 hydrogenation

Parr 3921 hydrogenation apparatus

The 3921 series Hydrogenator by Parr Instrument Company 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.

This hydrogenator is primarily used for synthesizing or modifying organic compounds through catalytic hydrogenation, reduction, or condensation. It’s suitable for any laboratory procedure where a liquid and gas must be mixed vigorously, often in the presence of a solid catalyst, in a glass reactor at pressures up to 5 atm. 

This reactor is used and reconditioned. Our technicians test all equipment to confirm that it operates properly and to the manufacturer’s specifications. While we can’t test for a specific analytical application, we will do our best to simulate the conditions under which the equipment will be run. If you have particular testing requirements or requests please let us know and we’ll work with you to make sure these requirements are addressed during testing.

The photos above are representative. Please bear in mind that the equipment shown is currently in storage in our warehouse and that in addition to testing each machine we will clean all the equipment thoroughly prior to shipment. We often have multiple units of each model in stock and sometimes we're unable to feature photos of every single unit. At your request, we can provide photos of the equipment in your order after it has been tested and cleaned.
