Steam Sterilizers are widely used in the sterilization of equipment, dressings, utensils, liquid medicine, culture medium and other items in universities, colleges, medical and health, food and chemical, biological research and other units. Before using it, we must understand the factors that affect the Steam Sterilizer.
(1) Water: Too high water temperature may cause the predetermined vacuum level to change, and the water temperature should be as low as possible. The water used in the sterilization pot should meet the quality of the application water, and the temperature should not exceed 15°C. The hardness value of water is between 0.7～2.0mmoL/L. Hardness values outside this range may cause problems such as scale and corrosion. So as to shorten the service life of the sterilization pot, the water used needs to be filtered and processed, and the pot body should be kept clean.
(2) Dryness of steam. The Steam Sterilizer should use saturated steam with a degree of dryness not less than 0.9, that is, the moisture content of the steam is not more than 10%, and the degree of dryness is not less than 0.95 under the metal load state to maintain a linear relationship between temperature and pressure.
(3) Sterilization time. Sterilization time refers to the time required for sterilization after the sterilization chamber reaches the specified temperature during the sterilization process. During operation, pay attention to the steam inlet speed and pressure, and generally keep the pressure and temperature rising simultaneously.
