6.9 Program 12: Bio Hazard Liquid (BH, bio-hazard models only)
For liquids when the manufacturer recommends autoclaving at
temperatures of 121ºC. for 45 minutes. All exhaust from the chamber
before completion of the Sterilization phase is performed through the
bio-hazard filter.
Nominal parameters default settings
Sterilization temperature: 121C (250F)
Sterilization time: 45 minutes
Operations sequence:
(PV, pre-vacuum model only) Air removal stage; four vacuum pulses
removes air by drawing the chamber down to 20 kPa.
Heating stage; steam enters the chamber and warms up until the
sterilization temperature is reached.
Sterilization temperature is maintained constant during the sterilization
time.
Slow exhaust; steam is slowly exhausted from the chamber, until it
reaches the required end temperature (approx. 85ºC) and the pressure
equals the atmospheric pressure.
