PARR 6050 Compensated Jacket Calorimeter This new calorimeter is the first designed by Parr to be controlled by your own personal computer allowing access to the calorimeter’s functions and tests. This new moderately priced, compact calorimeter combines a static jacket system with the convenience of automated oxygen filling. The new Model 6050 Compensated Jacket Calorimeter…
General InformationProduct Photos Windows can be installed in Parr stirred reactors and pressure vessels for visual observations, light transmission and other purposes. They usually are installed in pairs so that light can be introduced through one window while the other is used for viewing. Our standard material for these windows is fused silica. Sapphire is…
Sample Collection Vessels A sample collection vessel can be added to most reactor systems. Designed to efficiently and safely allow for the withdrawal of liquid or vapor samples at elevated temperatures and pressures, this quick close, O-ring seal vessel has a volume of 5 mL or 10 mL and is designed for operating pressures to…
High Pressure Gas BurettesLiquid Charging pipetteCatalyst Addition Devices High Pressure Gas Burettes Parr offers a series of high pressure burettes intended to introduce gas (commonly hydrogen) to a reactor at a constant pressure. The burettes consist of a high pressure reservoir equipped with an inlet valve, a pressure gage and a relief valve. A constant…
