Program 3: NoDry 121
Program 3 is recommended for sterilizing unwrapped instruments at a
temperature of 121
º
C / 250
º
F without drying stage, which its
manufacturer declares their compliance to be sterilized in the
conditions specified below.
Warning
This program is intended for tubing and other temperature sensitive
material and is not intended for patient use devices. The United States
Food and Drug Administration does not evaluate sterilization cycles for
non-patient use devices.
The solid load shall not exceed 8kg (17.6 lb).
Nominal
Parameters
Sterilization temperature: 121
º
C / 250
º
F.
Sterilization time: 20 minutes.
Max. cycle time: 40 minutes.
Average cycle time: 35 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 the chamber pressure equalizes to atmospheric pressure.
Note:
The sterility of instruments processed in unwrapped cycles cannot
be maintained if exposed to non-sterile environment.
