The aim of sterilization is to smash the possible potential threat that causes cross-infection of patients by killing micro-organism, including spores. To kill the micro-organisms, all instruments and materials used in dentistry are needed to be exposed to the steam at a specified temperature for a specified period of time to hold as recommended for steam sterilization method.

How does Class B autoclave work?

Following steps in Raga Dental Centre are meticulously followed in B-class autoclave:

  • First, we remove 99% of air inside the chamber by fractionated pre-vacuum air removal process. We use three pulses to evacuate air inside the autoclave chamber. The first pulse removes 80% of the air, leaving 20% inside. The second pulse extracts 80% of the remaining 20% air and leaving 4% of the initial air inside. Finally, the third pulse extracts again 80% of the remaining 4% air leaving less than 1% of initial air inside. And thus, we ensure 99% extraction of air from the chamber. This process helps to penetrate the steam into the deepest part of the load.
  • After removal of all most all air from the inside chamber, pressure, and temperature are increased.
  • Now we reached the actual sterilization stage where the pressure and the temperature are kept constant for a specified time period called holding period for sterilization process that ensures to say the micro-organisms goodbye.
  • After completion of holding period, the exhaust valve releases the pressure to come down to the atmospheric pressure.
  • The last phase is to dry out the load. We decrease the pressure inside the chamber, creating a vacuum therein and reducing the boiling temperature of 100 degree Celsius that evaporates the water on the load into gas, which finally sucked out by the vacuum pump.
  • Now the sterilization process is complete, the autoclave is safe to open and loads are ready to use.
