  1. The SolarclaveMedical Equipment Sterilizer Robert Thottam

  2. Autoclave • Device used to sterilize equipment and supplies via high pressure saturated steam

  3. Types of Autoclaves • Steam • Gravity Displacement • Positive Pressure Displacement • Negative Pressure Displacement • Dry heat

  4. Solarclave • Steam based • 2 Part • Pressure vessel • Reflector

  5. Pressure Vessel • Pressure Cooker • Layers of fiberglass insulation

  6. Reflector • 35 mirrors per section • Made of plywood

  7. Process • Orientation of reflector • 45-60 minutes to heat up to required temp • 121 degrees Celsius • 20 minutes to sterilize

  8. Advantages • Cost Efficient • Mobile • Sustainable • Easy to use • Primarily readily available materials

  9. Disadvantages • Weather dependent • Time Dependent • May require ordering/importing of some materials
