An
ultrasonic cleaner is one of the methods recommended by the Centers for Disease Control as the first step to remove tissue, blood and other contaminants from reusable instruments such as found in dental offices. Ultrasonic energy creates billions of minute bubbles in an ultrasonic cleaning bath that implode with tremendous force when they contact dental instruments. The process, called cavitation, reaches into tiny cracks and crevices, literally blasting contaminants away from the surface in a much more efficient manner than manual scrubbing, which has the additional disadvantage of requiring personnel to handle dirty instruments.
Only after a thorough ultrasonic cleaning should instruments move to the second and third stage: disinfecting and sterilization. That is because residue will interfere with microbial inactivation and can compromise subsequent processes, according to the CDC.

Laboratory refrigerators and laboratory freezers are designed and constructed to meet much stricter standards than typically found in household or commercial units. Pharmaceuticals, blood and plasma, for example, must be stored within tight temperature ranges to avoid loss of potency or spoilage. Lab refrigerators and lab freezers such as manufactured by Nor-Lake and available from Tovatech are built to meet the demanding requirements of pharmaceutical manufacturers and healthcare providers.
Design Options
Laboratory and healthcare provider purchasing agents can choose from a broad menu of sizes and configurations when looking for lab refrigerators and lab freezers. Common to all are heavy-duty refrigeration systems that work to maintain temperatures within prescribed parameters as programmed into incorporated temperature controls. Units also feature visual and audio high-low alarm systems to alert personnel if these limits are exceeded.

Technology and miniaturization have enabled manufacturers to place a powerful package of functions into a precision digital scale. As a result, these powerful, precise, compact and lightweight digital scales find use in the laboratory, in quality control departments, as industrial scales, and myriad other applications.
Multi-functionality is the term that best describes modern digital scales. A single scale, for example, can be used for such diverse tasks as check and recipe weighing, tolerance weighing, counting, dispensing, percentage determination, totalizing and more.
