Choosing Between Washer Disinfectors and Steam Sterilization

Washer Disinfectors

Washer disinfectors is simply the perfect solution to sterilize and clean reusable medical, dental and veterinary tools. Medical rules now recommend that, where practical, the usage of medical equipment like washer disinfectors rather than manual hand washing is preferred. Besides being a hygienic tool, a washer is an excellent method of sanitizing surfaces and instruments before a professional service is rendered on them. This will also make the instrument’s component (namely the drum) last longer and the machine itself more durable.

There are two basic types of washer disinfectors in use today. The first type uses a high-pressure stream of water at high pressure to induce steam and air-dry biological instruments and equipment in a chamber. High chamber volume is important because a larger area of water is used for effective sanitization. The second type of disinfectant uses a lower pressure stream of water at lower flow rates to achieve similar sanitization results. Both types of disinfectants have their own advantages and disadvantages depending upon their application and needs.

Central Station Sanitizing Racks: Central Station washer disinfectors are ideal for sanitizing small instruments like micro-scales and micrometerettes. Because of their lower surface area, these instruments can be exposed to high heat without causing any damage. High heat tends to destroy most bacteria, viruses and germs found in healthcare settings. However, when high heat is applied to an area with a clean or clear surface, biological contamination is lessened.

Thermal Sanitation and Heat Treatment: Thermo sterilizers have an advantage over central station sterilizers because they apply high temperatures to specific materials. These devices may include a water chamber or a tank of hot water. As materials are heated in the water chamber, microorganisms are killed using appropriate methods. Some examples include oxidation, cold nucleation, and superirradiation. The tank of hot water is usually outside the facility while the hot water solution is used to clean surfaces inside the building. This type of washer disinfectors may be automated or manual, depending upon the applications.

Self Installation and Connectivity: A final option includes self-installation. Commercial instrumentation used in the cleaning industry requires regular replacement of parts. Self installation of washer disinfectors eliminates this need because it can be installed by the user. Tools for installation are available at most specialty equipment suppliers. These instruments are easy to install with minimal supervision.

In general, washer disinfectors offer more sanitary protection than steam sterilization. However, some situations dictate the use of both tools. Washer instruments are often the preferred choice of professionals and consumers because they offer a more effective cleaning method over steam sterilization. They also come with safety features to reduce the risk of serious injury from chemical exposure.
