    Why are my Tuttnauer Laboratory Equipment sterilization results unsatisfactory?
    • A
      Austin NunezSep 16, 2025
      If you're experiencing unsatisfactory sterilization results, consider the following possible causes: * There might be incomplete removal of air pockets. * Sterilization conditions might involve improper temperature or pressure being too low, or the sterilization time being too short. Set the correct temperature and time according to the type and quantity of material. * Incorrect loading of the autoclave may be trapping air in the load.
