Operation Guide
Pre-sterilization Cleaning and Disinfection of Instruments and their Loading into the Device
Caution! Instruments should not be loaded into the autoclave to be sterilized unless Steam Sterilization is instructed in their User Manual. The instructed Steam Sterilization Program should be verified against the programs available in this autoclave.
Caution! Never use the autoclave to sterilize corrosive products (acids, bases, or phenols) volatile compounds or solutions (ethanol, methanol or chloroform), or radioactive substances.
The most important stage begins with removing debris by cleaning and rinsing. Effective cleaning is affected by several factors: water quality, type, concentration and quality of a cleaner, effective washing method, and adequate rinsing and drying.
Cleaning dried blood is especially difficult because it flows and dries in difficult-to-clean locations. It shall be washed away. Mechanically scrubbing, high pH detergents, enzymatic solutions, and water spray at high pressure will clean this contamination.
Note: Consult the Medical Device manufacturer relating adequate and most effective cleaning method and cleaning agents.
Instruments which are composed of several components shall be dismantled.
Disinfection is the next step. It is important for safe handling. There are various methods and means for disinfection like soaking in liquid chemical disinfectants or hot water disinfection.
Packaging. The target in packing medical items is to assure that the contained goods are sterile and maintaining them sterile till opening the package.
There are various methods and techniques used in preparation and packaging of surgical instruments.
Check the instructions of the item manufacturer as to the proper procedure for cleaning and sterilizing each item. The item manufacturer’s instructions always supersede any other instructions.
- Clean instruments immediately after use to remove any residue. It is recommended that all instruments be ultrasonically cleaned using Tuttnauer’s Clean & Simple enzymatic cleaning tablets or other suitable solution.
- After cleaning, rinse instruments under tap water for 30 seconds and pat or air dry to remove residual minerals. If your tap water has a high mineral content, then rinse a second time in a bath of distilled water to remove minerals and pat dry.
- Launder textile wraps prior to sterilization, thoroughly rinse wraps laundered in chlorine bleach. Chlorine bleach can harm your stainless-steel instrument and the sterilizer.
- Follow the instrument manufacturer’s instructions on the use of products for cleaning and lubricating instrument that have been ultrasonically cleaned.
- Be sure that instruments of dissimilar metal (stainless steel, carbon steel, etc.) are separated. Carbon steel instruments should be bagged or placed on autoclavable towels and not directly on stainless steel trays (mixing will result in damage to the instruments or trays from the oxidation of these materials).
- Load items within the boundaries of the tray so that they do not touch the chamber walls or fall off when the tray is moved. Items should not be allowed to touch the walls of the Chamber as the hot metal can damage the item.
- Don’t overload the Sterilizer trays (see Specification). Overloading will cause inadequate sterilization & drying.
- Make sure that all instruments remain apart during the sterilization cycle. Surfaces that are hidden because items are covering other items will not be exposed to the steam and will not be sterilized.
- Disassemble or sufficiently loosen multiple-part instruments prior to packaging to permit the sterilizing agent to come into direct contact with all parts of the instrument.
- Verify that packaging methods are in accordance with the good practice approach and the packaging materials used are in agreement with applicable standards.
- Tilt on edge items prone to entrap air and moisture, e.g. hollowware, so that only minimal resistance to air removal exist, the passage of steam and condensate will be met.
- Wrapped instruments should be placed in material which will allow steam penetration and promote drying, such as autoclave bag, autoclave paper, or muslin towels.
- When loading pouches on the tray, put them with paper side up, nylon side towards the tray (see the figure below)
- Tubing should be rinsed after cleaning. When placed in the tray, make sure that both ends of the tubing are open and there are no sharp bends or twists.
- Cassettes should be placed on the tray rack in place of the trays. They should not be touching each other or the Chamber walls. There should be about 1″ (2.5cm) between cassettes or packs for proper steam circulation.
- If spotting is detected on the instruments it is necessary to determine if the spot is dirt or rust. The first step would be to use an ordinary eraser to remove the spot. If there is no pitting under the spot, then the spot is only dirt. Dirt spots on an instrument may be an indication that the autoclave needs to be cleaned or that the instruments were not adequately cleaned or dried prior to sterilization. If removal of the spot reveals pitting, then the spot is most likely rust. Rust spots on an instrument are not uncommon on inexpensive instruments. It may also be an indication that the instruments were rinsed in tap water with a high mineral content. These minerals when exposed to high temperature and steam will accelerate the oxidation of the metal. One suggestion would be to final rinse the instruments in a distilled water bath and pat dry to absorb residual water and minerals.
- If the instruments exhibit a discoloration this can be due to the mixing of carbon steel and stainless steel. When these two metals come into contact with each other electrolysis occurs that breaks down the metal. The best solution is to separately wrap the carbon steel instrument to insulate it from other instruments on the tray and the tray itself.

Class S and Class B
Class B: General description
Class B (that conform to the European standard) mainly provides deeper vacuum in the autoclave chamber than Class S, therefore, includes a more complete air removal from the most difficult load types. It allows the system to perform vacuum in difficult hollow or porous instruments and perform effective sterilization of these materials.
Class S: General description
Class S used in the USA obtain weaker vacuum level and is less effective than Class B in the sterilization of hollow instruments.
The following tables provide:
