2. GENERAL INFORMATION
2-1. Operating Principles
Autoclave or “High Pressure Steam Sterilizer” is an apparatus used to sterilize articles by
subjecting them to saturated steam under pressure above atmospheric pressure.
When the FLS-1000 starts operation, sterilizing water inside the chamber is heated up by the
element heater at the bottom of the chamber to generate steam.
The steam generated from heated water drives air out from the chamber and warms up the
interior of the chamber. When the temperature sensor inside the chamber detects that the set
sterilization temperature is reached, the set temperature is maintained for the set period of
time. The air remained inside the chamber is removed during this process. When the set time
has elapsed, the valve closes to start heating.
When the temperature sensor detects that the set temperature is reached, the timer starts to
maintain the set temperature. When the set sterilizing time has elapsed, the heater stops. The
sterilizing action is determined by the three elements: temperature, humidity and time that are
applied to articles to be sterilized during this process of the sterilization cycle.
When the chamber temperature drops, the valve opens to allow the pressure inside the
chamber to fall back to the atmospheric level. When the temperature sensor detects that the
chamber temperature falls to the set value for the lid interlock release temperature, the buzzer
sounds and the indicator turns on to indicate that the operation is completed.
If any abnormality occurs during the operation, the FLS-1000 enters safe mode, the display
shows an error code and the buzzer sounds.
During the sterilization process the temperature is maintained 2℃ of the set
temperature. When the temperature drops below the set value, the timer countdown stops.
When the temperature exceeds the set value, the timer countdown starts again.
