5.2. Program 2: P 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 134ºC/273ºF 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: 134ºC (273ºF).
• Sterilization time: 18 minutes.
• Dry time: 20 minutes.
• Max. cycle time: 55 minutes.
• Average cycle time: 48 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 pressure equalizes
atmospheric pressure.
