Program 8: Bio Hazard 2 (BH, bio-hazard models
only)
All exhaust from the chamber before completion of the
Sterilization stage is performed through the bio-hazard filter
. For
instruments, when the manufacturer recommends autoclaving at
temperatures of 121
C (250
F) for 45 minutes. Drying stage is
available for PV (pre-vacuum) models only.
Nominal parameters default settings
•
Sterilization temperature: 121
C (250

•
Sterilization time: 45 minutes
•
Drying time: 1 minute. (PV
– pre-vacuum models only).
Operations sequence:
•
(PV, pre-vacuum models only)
Pulse low/Pulse high:
at one pulse it
will build vacuum down to 25 kPa.
All exhaust from the chamber is
performed through the bio-hazard filter.
•
Water Inlet:
Water enters the chamber
•
Heating:
The chamber is heated by actuation of electrical heaters
until the sterilization temperature is reached.
•
Sterilization:
Sterilization temperature is maintained constant during
the sterilization time.
•
Cooling:
N/A
•
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. Some water may remain in the chamber after a failed
