Air and other gases contained in a freshly filled ultrasonic cleaning bath interfere with the cleaning performance of the ultrasonic cleaner. Evidence of these gases can be seen as bubbles that form on the inside of a standing glass of warm water. Ultrasonic cleaning is accomplished by the energy released from the violent collapse of tiny vacuum-filled bubbles. Air bubbles and dissolved air in the cleaning liquid absorb ultrasonic energy and inhibit the implosion of these cavitation bubbles, significantly reducing the cleaning effect.
Air can also be introduced as bubbles clinging to objects immersed in the ultrasonic bath.

A controlled environment is critical to maintaining the potency and safety of pharmaceutical products across a supply chain stretching between R&D laboratories, manufacturing facilities, transportation and storage at healthcare facilities. Examples of controlled environments include laboratory refrigerators, laboratory freezers, blood bank refrigerators, chromatography refrigerators, laboratory incubators, stability chambers and temperature test chambers.
Equipment such as this as manufactured by Norlake Scientific and offered by Tovatech is designed and constructed to comply with standards developed and promulgated by the FDA, the AABB, the Red Cross and other agencies. Once the equipment is purchased, however, the facility operator assumes the responsibility of assuring it is installed and maintained according to FDA and related guidelines.

Ultrasonic cleaners find wide application throughout industry for removing a host of contaminants in a fast, safe and efficient manner through the power of ultrasonic cavitation. Despite the wide range of sizes and features available in off-the-shelf ultrasonic cleaners, occasions arise that call for incorporating specific features in the cleaning equipment. In such cases a custom ultrasonic cleaner provides the solution.
The sizes of items being cleaned, their physical configuration or a particularly difficult cleaning operation are among the factors that could lead to a custom ultrasonic cleaner. Ultrasonic equipment providers such as Tovatech are staffed by engineers with the technical expertise to solve these cleaning problems, often at costs comparable to off-the-shelf units.

Infection control is more crucial than ever as healthcare practitioners face increasing caseloads of diseases and viruses as well as treating victims of violence, accidents, natural and human-caused disasters. Proper cleaning of instruments used in treatments has two benefits, most important of which is to help ensure infections are not accidently transmitted to other patients. Moreover, reusing properly cleaned and disinfected instruments can help lower costs for treatment facilities.
In a three-step process the World Health Organization has established practical guidelines for infection control in healthcare facilities: cleaning, disinfection and sterilization. An ultrasonic cleaner is faster, safer, and more thorough than scrubbing, soaking, and even using steam. But as the WHO cautions, it is not a substitute for disinfecting and sterilization. Instead, it can be an important step in cleaning instruments after gross contamination is removed by manual or automatic scrubbing.
