The Heater
The heater is the first part of the sterilization process where Nichrome ribbons are heated using electricity The temperatures of theses coils/flexible heaters is precisely controlled using PTC thermistors ( temp sensors ) The coils can reach up to 200*C After Opening the upper lid. The media is to be poured through the funnel. The machine consists of a quartz tube which is divided in parts Each part follows a specific function. After every function the media is monitored (temp sensors)
The UV Chamber
The second part consists of the UV chamber which is intensity controlled The 3 Uv tubes are 60watts each and can further sterilize the given media through uv penetration, After each of the above section there exists a valve to adjust the flow or to cut it off completely
The Clean (sterile) chamber
The final part is a chamber with a blower and hepa filters that which push sterile air through the chamber and the opening unit where the petri plate is to be placed . The plate is to be places carefully after sliding the lid up. The plate is placed on the conveyor which is controlled by a knob that has a restricted rotation. Once the knob is fully rotated the plate will reach tight under the tube which will release the sterile media. The screen and buttons help control the temperature UV exposure Solonoid valves. The outer body is non UV penetratable Polycarbonate.
