Runyes Feng 23L – Class B Autoclave with USB Recorder

B+ cycle is also known as the Prion cycle, in this cycle, the sterilization holding time is for 18 min to destroy the heat resistant prion bacteria on the reusable dental instruments and provide 100% sterilized instruments before surgical procedures or dental implant procedures.

B class steam sterilizers have triple vacuum cycles that help in effective sterilization of reusable dental instruments. Due to vacuum cycle the trapped air inside porous or hollow instruments gets evacuated properly and then the steam gets penetrated into the instruments for effective sterilization. So, B class autoclave is only recommended due to easy sterilization of solid/hollow, porous/non-porous, wrapped/unwrapped instruments.

B & D test i.e. Bowie and Dick test in the autoclave is used to check proper temperature penetration into the dental instruments for proper sterilization. A litmus paper is wrapped in a gauze piece and kept inside the autoclave. Then the sterilization cycle is started. After the cycle completes, if the litmus paper colour is changed from pink to blue or black, then the autoclave is B&D test qualified and doing 100% sterilization.

Before starting of the sterilization cycle, the date, time and year etc. is saved through STEP button on the control panel. Once the cycle completes, the USB is connected to the USB port available on the front control panel of the autoclave. Once the data gets downloaded to the Pendrive, the light blinks. The Pen drive now can be removed and connected to any desktop or laptop to check the sterilization cycle.

As the name suggests, the steam spray barrier prevents direct spray of steam on the instruments and thus prevent rusting or damage to the instruments. Due to the steam spray barrier, the steam inside the chamber evenly disperses in the chamber.
