Steam Sterilizer

Product Details:

WIST- Autoclaves use steam heat to kill any microbial life that may be present on a contaminated load. A load — also known as goods — is considered sterile once it has undergone a full sterilization cycle. Once a load is sterile, it can be used without fear of introducing foreign microorganisms into a sensitive environment, such as a laboratory, hospital operating room, food production facility, and so on. Different types of goods must be sterilized for different lengths of time and at different temperatures. Some autoclaves include additional features, such as vacuum functions, special cycles, and integral electric boilers.

For a more detailed explanation of the various phases of a sterilization cycle, please refer to the list and image (Figure 2) shown below:

1. Purge Phase: Steam flows through the sterilizer and starts to displace the air; temperature and pressure ramp slightly to a continuous flow purge.

2. Exposure (Sterilization) Phase: During this phase, the autoclave’s control system is programmed to close the exhaust valve, thereby causing the interior temperature and pressure to increase to the desired setpoint. The program then maintains the desired temperature (dwells) until the desired time is reached.

3. Exhaust Phase: Pressure is released from the chamber through an exhaust valve and the interior is restored to an ambient pressure (though contents remain relatively hot).1. Vessel

The vessel is the main body of the autoclave and consists of an inner chamber and an outer jacket. Laboratory and hospital autoclaves are constructed with “jacketed” chambers (see Figure 4), where the jacket is filled with steam, reducing the time that it takes to complete a sterilization cycle and reducing condensation within the chamber. A vessel designed and manufactured with a full jacket is superior to that of a partial jacket or blanketed jacket for the following reasons: a full jacket improves temperature uniformity within the chamber, it reduces the likelihood of wet packs, and helps minimize wet steam, which is not good for sterilization.

In the United States, every autoclave vessel is inspected and tagged with an American Society of Mechanical Engineers (ASME) nameplate that includes a National Board number. Manufacturers are required to hydrostatically test each vessel and apply an ASME nameplate before putting an autoclave into use. This inspection and the ASME nameplate are key indicators of a properly functioning autoclave.

Laboratory and hospital autoclave vessels can vary in size, from 100L to 3,000L, and are typically constructed from 316L stainless steel. Inner chambers are either 316L or nickel-clad, and outer jackets are made of 316L, 304L stainless steel, or carbon steel.
