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…
General InformationSpecifications Parr offers two styles of condensers for attachment to the head of a stirred reactor or pressure vessel. These can be made in various sizes to match the size of the reactor The reflux condenser consists of a length of tubing connected directly to the head of a vessel and equipped with a…
Static Catalyst BasketDynamic Catalyst Basket The Static Design In the static design the mesh basket holding the catalyst remains stationary while impellers on the stirring shaft and baffles outside of the basket direct the flow of reactants over the surface of the contained catalyst. A unique gas entrainment impeller provides a uniform flow of both…
Standard StirrerGas Entrainment ImpellersBaffles All stirrer options may not be appropriate or available for each reactor size. Additional internal fittings may be required to adapt some stirrer styles to existing reactors in the field. Please contact us for assistance in selecting a stirrer suitable for the intended operating volume and viscosity. The stirrer option shown…
