ME 462 Capstone Design
Pressurized Reactor
Presented by:

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
