Semi-automatic disinfection of water circuits BIOSTER S is the new semi-automatic system that disinfects the spray circuits. Managed via the instrument control panel, the system makes use of the disinfectant liquid contained in a special tank, identified by a yellow stripe, applied in place of the independent feed tank. Effective disinfection in just a few simple steps To use the BIOSTER S system it is necessary to replace the independent feed tank with a second tank, reserved for disinfectant liquids. After placing the instruments above the cuspidor bowl in the special container, the dentist starts the disinfection process manually; the hydrogen peroxide liquid must remain inside the circuits for 10 minutes. At the end of the disinfection process the dentist must reconnect the distilled water tank to carry out the final circuit rinse. The system carries out disinfection of all the circuits simultaneously. Starting and ending the process requires only minimal manual intervention. Optional on S220TR and S200.
