5.8 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 121C (250F) for 45 minutes. Drying stage is
available for PV (pre-vacuum) models only.
