Program 5: Delicate 121
Program 5 is recommended for sterilizing delicate instruments at
temperatures of 121ºC / 250
º
F with slow exhaust, which its
manufacturer declares their compliance to be sterilized in the following
conditions:
The solid load shall not exceed 8kg (17.6 lb).

F).
Sterilization time: 20 minutes.
Max. cycle time: 55 minutes.
Average cycle time: 45 minutes.
Operation
Sequence
Air removal phase; two vacuum pulses as described in the diagram
below. Saturated steam is introduced into the chamber until the
sterilization temperature is reached.
Sterilization phase; temperature and pressure are maintained
constant at the pre-set level for the sterilization time.
Slow exhaust phase; steam is slowly exhausted from the chamber
by pulses of the exhaust valve, until the chamber pressure equals
atmospheric pressure.
