Description of a program
Process status screen
If a program is running, the MONITOR window is visible. In the monitor window, all important
information about the current cycle is displayed. The following information can be found (additionally
marked in the screenshot below).
Name of the running program.
Status of the running program. This can be “Running”, “Finished”, “Prepare to start”, “Not
running
”.
Description of the running program.
Current temperature in [°C] and pressure in [kPa], measured in the chamber.
Graphical overview.
Operation of Cycles
If activated in the program, the autoclave will first be aired.
Any air remaining in the chamber makes the temperature distribution in the chamber uneven. This
hinders temperature rise (sterilization). To cope with this, a microcomputer-controlled automatic
exhaust valve vents out virtually 100 % of the air in 10 minutes at 115°C. In the chamber remains
water steam. At the end the valve closes.
Sterilization Cycle
A constant temperature (pressure) is maintained during the set sterilization time period. If the
temperature in the chamber drops 1°C or more or rises 2°C or more from the set value due to any
trouble, the program is interrupted.
In sterilization of petri dishes or empty containers, the air remaining in the container expands and may
increase the pressure extraordinarily within the chamber. If the pressure in the chamber exceeds the
saturated steam pressure, the automatic exhaust valve opens and discharges the air in the chamber
into the exhaust bottle.
