Pressurized Reactor ME 462 Capstone Design Presented by: Rita Russell Adam Schulte Shahid Osman Tiffany Urias
Objective To design an enclosed container to safely encase test tubes held in a reaction rack, be able to supply heat from an outside source, and provide a pressurized anaerobic environment while transmitting a magnetic field for stirring.
Design Specifications Exterior case with removable reaction tube rack Fixed size of tube rack; racks with different tubes interchange Thermo-stated case with heating 25-150 ºC Pressure range of 0-100 psig; vacuum desirable Non-magnetic for all materials used Stirring of contents via magnetic field through the case Minimize distance between tube rack bottom and the outside bottom Quality of the seal is critical for small scale runs (evaporation)
