Compact Dry ETB (Enterobacteriaceae) Compact Dry ETB is a simplified medium to determine number of Enterobacteriacae by the combination of selective agents and pH indicator. Approved AOAC Certificate Number: 012001 MicroVal Certificate of Compliance Number: 2008LR02 (MV0806-002LR) NordVal International Certificate Number: 034 Characteristics Colonies grown on ETB plate are distinguished by red/purple color for Enterobacteriaceae.…
Compact Dry SL (Salmonella) Microval Characteristics The presence of Salmonella in the sample is detected by the combination of 3 different test principles, alkalization of the medium (medium color change to yellow), greening colonies (black also), and motility of Salmonella. Approved MicroVal Certificate Number 2022LR110 Incubation Pre-enrichment culture : 36±1℃ for 20-24 hours Incubate at 42±1℃ for 22±2 hours Result Interpretation…
NC TECHNOLOGIES ECS 8020 CHNS-O ELEMENTAL COMBUSTION SYSTEM – ELEMENTAL ANALYZER The ECS 8020 is a C, H, N, S, O Elemental Analyzer Model based on the Dumas combustion method. It represents an evolution of elemental analysis techniques based on sample combustion and chromatographic separation. The combustion product, i.e. CO2, H2O, SO2 and N2 are…

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…
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…
