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…
This system incorporates three tubular reactors that can be configured as required to operate in a strictly parallel fashion or in a cascade arrangement where the products from one reactor are immediately directed to a second reactor. This type of system can support reaction schemes including but not limited to the Fisher- Tropsch process,…
General InformationSchematic Example A supercritical fluid is any substance at a temperature and pressure above its critical point. Such fluids can diffuse through solids like a gas and dissolve materials like a liquid. Near the critical point, small changes in pressure or temperature result in large changes in density, allowing many properties of a supercritical…
General InformationProduct PhotosSpecification Stirring biomass is not easy to do in a vertical reactor. A line of reactors has been developed by Parr Instrument Company to function horizontally. Horizontal reactors enable researchers to mix bio feed stock and other cellulosic material such as: • straw • corn stover • sugar cane • grasses • plants…
Sylab – Thermogravimetric Analyzer TGA 3000 Sylab’s TGA 3000 is an automated instrument which determines Moisture content, Ash content, Volatile content, Loss on Ignition (LOI) and Fixed Carbon content in a wide range of Organic, Inorganic and Synthetic materials. Thermogravimetric analysis replaces the traditional analytical techniques that are slow, labor intensive and involve several steps…
Parr Instrument Company manufactures non-stirred vessels for the decomposition of biomass in ammonia and steam. Parr stirred reactors, including a new horizontal reactor technology, have been designed for research processes that include hydrogenation, isomerization, and metathesis reactions. In addition, fully customizable continuous-flow tubular reactor systems have been developed with continuous reactant feed and product handling…
General InfoAccesoriesFluidized Bed ReactorSchematic ExamplesCustom Examples Tubular reactors are always used in a continuous flow mode with reagents flowing in and products being removed. They can be the simplest of all reactor designs. Tubular reactors are often referred to by a variety of names: • Pipe reactors • Packed-bed reactors • Trickle-bed reactors • Bubble-column…
General InformationSpecificationProduct PhotosCustomize Multiple Reactor System The Parr Series 5000 Multiple Reactor System has been designed to provide an integrated system for running multiple reactions simultaneously and applying the principles of high throughput experimentation to reactions conducted at elevated temperatures and pressures. The principal features of the 5000 System include: • Six reactors with internal…
