Tuttnauer 3140EA - Sterilization Programs Overview; Program 1: Unwrapped Instruments

23
4 STERILIZATION PROGRAMS
The autoclave offers 3 sterilization programs, at temperatures of up to 274F
(134C), with or without a drying stage and 1 accessory (dry only) program.
A. Three sterilization programs:
1. Unwrapped instruments.
2. Wrapped instruments and porous loads.
3. Glassware.
B. Accessory program:
1. Dry only.
Note: The nominal data of
the program (default settings) can be changed to fit the needs of
a particular office. This is done by means of the TEMP, STE.TIME, DRY TIME,
keys in combination with the UP or DN keys, as described in sec 3.2.2.
4.1 PROGRAM 1. Unwrapped Instruments
For unwrapped instruments and materials, when the manufacturer
recommends autoclaving
at temperatures between 250F and 274F
(121C and 134C) no preset drying stage required.
Nominal parameters default settings
 Sterilization temperature: 273F (134C).
 Sterilization time: 3 minutes.
 Dry time: none.
Operations Sequence
 Heating by actuation of electrical heaters until the sterilization
temperature is reached.
 Sterilization
temperature is maintained constant for the preset
sterilization time.
 Fast exhaust, steam is exhausted out of the chamber at a fast rate until
pressure drops to zero.
Note:
The sterility
of instruments processed in unwrapped cycles cannot be
maintained if exposed to a non-sterile environment.
