Program 2: WDry 134
Program 2 is recommended for sterilizing double wrapped instruments,
porous loads and Hollow A (e.g. dental hand pieces, suction pipes)
loads at temperatures of 134
º
C / 273
º
F with 20 minutes drying stage,
which its manufacturer declares their compliance to be sterilized in the
following conditions:
The solid load shall not exceed 8kg (17.6 lb).
The porous load shall not exceed 2kg (4.4 lb).
Nominal
Parameters
Sterilization temperature: 134
º
C / 273
º
F.
Sterilization time: 4 minutes.
Dry time: 20 minutes.
Max. cycle time: 50 minutes.
Average cycle time: 42 minutes.
Operation
Sequence
Air removal phase; three 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.
Fast exhaust phase; steam is rapidly exhausted from the chamber,
followed by a continuous vacuum pulse for the drying stage,
followed by vacuum break (air inlet), until the chamber pressure
equalizes to atmospheric pressure.
