Program 12: Bio Hazard (BH, bio-hazard models only)
For instruments, when the manufacturer recommends autoclaving at
temperatures of 134
C (273
F) for 30 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: 134
C (273
F)
Sterilization time: 30 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.
Fast exhaust, the steam is exhausted out of the chamber at a fast rate
until pressure decreases to ambient pressure.
Note: If the cycle fails, fast exhaust is performed through the bio-
hazard filter.
(PV, pre-vacuum model only) Drying stage; vacuum is built up and
the coil heats the chamber for 15 minutes.
