Page 24 of 66 Pages
4.2 Program 2 (2- Instruments)
For instruments and materials when the manufacturer recommends
autoclaving at temperatures of up to 121ºC with a drying cycle.
Nominal parameters
 Sterilization temperature: 121ºC (250ºF).
 Sterilization time: 15 minutes.
 Drying time: 15 minutes.
Operations Sequence
 Heating phase; water enters the chamber and warms up until the
sterilization temperature is reached.
 Sterilization phase; temperature is maintained constant at the preset
level for the sterilization time.
 Fast exhaust phase (Ex Mode=1); steam is rapidly exhausted from the
chamber, until pressure equalizes to atmospheric pressure.
 Drying phase; Chamber is heated for 15 minutes at reduced power.
