For 120 years, Parr Instrument Company has been designing and building pressure vessel-based laboratory equipment.
Parr Reactors and Pressure vessels are rated for use at elevated temperature and pressure and can be used for applications from catalyst screening at the milligram scale to fine chemical production at the multi-kilogram scale. Models from 5 mL to 100 L are available and can be constructed from stainless steel or other corrosion-resistant alloys.
Our Stirred and Tubular Reactors can be customized with gas and liquid feeds, interchangeable reactor modules, and product collection and online analysis options, with full PLC control.
Parr is also recognized as the global leader in the supply of Oxygen Bomb Calorimeters for the determination of the heat of combustion of solid, liquid, and refuse derived fuels like coal, coke, fuel oil, gasoline, combustible wastes, refuse disposal, foodstuffs, explosives, heat powders, and nutritional supplements.
