Where is an autoclave used

In general, pipette tips should only enter the autoclave as waste inside of an approved biohazards bag and always sterilized on a steam-producing setting.

Before using the autoclave, check inside for any items left by the previous user that could pose a hazard. Clean the drain strainer before loading the autoclave. Always place items in a secondary container. Do not overload or package bags too tightly. Leave sufficient room for steam circulation. If necessary, place container on its side to maximize steam penetration and avoid entrapment of air. Use only autoclavable bags to package waste. Do not allow bags to touch the interior walls of the autoclave to avoid melting of plastic.

Ensure sufficient liquid is packed with contents of autoclave bags if dry. Place soiled glassware and lab ware in secondary containers and autoclave them in the solids cycle. Loosen caps or use vented closures. In case of clean glassware and wrapped instruments, lay them in a secondary container before autoclaving in wrapped goods cycle.

For secondary containment, use autoclave trays made out of polypropylene, polycarbonate or stainless steel. The trays should have a solid bottom and sides to contain the contents and catch spills. Choose appropriate cycle for the material. Incorrect selection of cycle may damage the autoclave, cause liquid to boil over or bottles to break. Start your cycle and fill out the autoclave user log. A completed cycle usually takes between 1 to 1.

Close and lock door. Do not attempt to open the door while autoclave is operating. Unloading Ensure cycle has completed and both temperature and pressure have returned to a safe range. The autoclave is recognized by the FDA and classified as an article of medical equipment. Autoclaves are found in many medical settings, laboratories, and other places that need to ensure the sterility of an object. Autoclaves work by bringing water to a boiling point, creating steam inside a sealed chamber.

Once the saturated steam reaches between F and F a thermostatic valve which releases the air inside the chamber during heat up closes, this causes the chamber to pressurize. A pressured chamber full of saturated steam will have a consistent temperature throughout. The autoclave will continue to heat the steam until it reaches F or F depending on the temperature needed to sterilize the subject matter. Today, in the aircraft industry, investments in these type of equipment is regarded to be strategically important.

Beyond the initial cost of the autoclave, the maintenance and cost of sterility assurance and monitoring products should be considered. Depending on the autoclave manufacturer, the costs per cycle, utility consumption and maintenance costs could vary over time and should be evaluated to compare your total-cost-of-ownership over time. Autoclaves may be used in a variety of industrial and medical applications. Industrial autoclaves are used in manufacturing environments to process parts and materials using heated steam and pressure: for example, in the manufacturing of pressure treated woods and specialized rubbers used in the tires of your car.

Autoclaves are also used in the scientific research and pharmaceutical industries — beyond sterilizing equipment used in laboratory research most autoclaves come equipped with a liquid cycle to sterilize liquids used in laboratory environments. Medical steam sterilizers are used in healthcare environments for the sterilization of heat and moisture-stable items such as surgical instruments, implanted medical devices and surgical drapes and linens.

The cycles used in medical steam sterilizers are developed and validated according to recognized industry standards. In the United States, steam sterilizers used in healthcare must be cleared for use by the Food and Drug Administration for the sterilizer manufacturer's stated intended use.
