5.1. Program 1: Flash 134
Program 1 is recommended for sterilizing unwrapped instruments, at
temperatures of 134ºC/273ºF with 1 minute 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).
Nominal Parameters
• Sterilization temperature: 134ºC (273ºF).
• Sterilization time: 4 minutes.
• Dry time: 1 minute.
• Max. cycle time: 25 minutes.
• Average cycle time: 15 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.
• Fast exhaust phase; steam is rapidly exhausted from the chamber
until pressure equalizes atmospheric pressure.
Note:
The sterility of instruments processed in unwrapped cycles cannot
be maintained if exposed to non-sterile environment.
