The SolarclaveMedical Equipment Sterilizer

Robert Thottam

Autoclave Device used to sterilize equipment and supplies via high

pressure saturated steam

Types of Autoclaves Steam

Gravity Displacement Positive Pressure Displacement Negative Pressure Displacement

Dry heat

Solarclave Steam based 2 Part

1. Pressure vessel

2. Reflector

Pressure Vessel Pressure Cooker Layers of fiberglass

insulation

Reflector 35 mirrors per section Made of plywood

Process Orientation of reflector 45-60 minutes to heat up to required temp

121 degrees Celsius

20 minutes to sterilize

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

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