1. Pressurized Reactor ME 462 Capstone Design Presented by: Rita Russell
Adam Schulte
Shahid Osman
Tiffany Urias

2. 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.

3. Design Specifications
Exterior case with removable reaction tube rack
Fixed size of tube rack; racks with different tubes interchange
Thermo-stated case with heating ºC
Pressure range of 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)
