You might have seen something like this in your dentist's office or the doctor's office. You might have even asked what is that and what is doing.
The friendly dental assistant might have told you it is an ultrasonic cleaner for cleaning the instruments.
What is it really doing?
First of all, it can be used to clean more than dental instruments. It can be used to clean jewelry, lenses and optical parts.
It has a chamber to hold the cleaning solution (specially designed for the ultrasonic cleaners) and a wire basket to hold the instruments. The ultrasonic cleaner uses ultrasound for cleaning.
Actually, the sound waves produces millions of bubbles in the solution, which implode. This cavitation process helps to loosen the blood saliva and plaque from the instruments. It is done in a microscopic level, which is far better than hand scrubbing the instruments by hand. This cleaner helps to remove debris from the tiny crevices and pores of the instruments.
Your dental assistants will wash the cleaned instruments and then sterilize them in autoclave or statim.
Now, there are small ultrasonic cleaners available in the market to be used at home. You can have one to clean your precious gold and silver jewelry or eyeglasses or dentures at home.
The iSonic one can be bought with less than $50.
Then on Instructables I saw this homemade ultrasonic tank.
Can it be used to remove that annoying dirty marks from the shirt collars too?
What else you want your ultrasonic cleaner to do for you?
