Details About 3.2L Dental Ultrasonic Cleaner Without Drain Vavle

Why You Need A Hongsonic Ultrasonic Dental Instrument Cleaner?

Ultrasonic cleaners are important contributors to achieving strict infection control procedures in dental clinics. Reusable dental instruments (as with surgical and medical instruments) in contact with patients’ blood and tissue must undergo a rigid three-part procedure that first removes gross contaminants, then thorough scrubbing/washing and finally either sterilizing or disinfecting. The role of an ultrasonic cleaner in cleaning dental instruments comes into play in the middle of this cycle.

How Hongsonic Ultrasonic Dental Instrument Cleaner Works?

An ultrasonic cleaner is simply a metal tank [stainless steel] that has piezo ceramic transducers bonded to the bottom or side. These transducers have a unique property of changing size almost instantly when excited by an electrical signal. When excited the transducer increases in size and causes the tank bottom or side to move. This creates a compression wave in the liquid of the tank.

By using an electrical generator that puts out a high-frequency signal [20 to 250 kHz] the transducer rapidly induces compression and rarefaction waves in the liquid. During the rarefaction cycle, the liquid is torn apart. This creates a vacuum cavity within the liquid. These cavities will grow larger and smaller as the compression waves are continued. When the cavity reaches a certain size [based on the frequency and the wattage of the signal] the cavity can no longer retain its shape. The cavity collapses violently and creates a temperature of 5,000 degrees centigrade and a jet of plasma that impacts against whatever object is in the tank. There are millions of these bubbles created and collapsing every second in an ultrasonic tank.

Cleaning and Disinfecting Dental Instruments


The actual cleaning of dental instruments and similar items in an ultrasonic washer is a fairly simple affair:

  1. The number one thing on your to-do list for this process is to have a test for clean. Without an objective standard for cleanliness, how can you tell if the job is done? Since we are concerned mainly with removing organic debris, this can be as simple as the following: “When observed under 20x magnification, the instruments have no detectable soil remaining.” If you check your facility’s regulations, you will most likely find that this spec already exists.
  2. Briefly rinse the instruments. While your cleaner will remove even the most tenacious soils, there is no reason to contaminate your cleaning solution with easily rinsed off debris.
  3. Fill the tank to the indicated “fill line” with clean water and disinfectant/cleaning solution. The temperature should be set to 150-160 degrees Fahrenheit. If your tank has a simple ON/OFF heating function, this is where it is most likely set. Manual Hongsonic tabletop units, for example, will heat up to about 156F. If you can adjust the heat, set it to about 80% of the maximum. Remember that while ultrasonic cleaning will remove soils, it does not on its own disinfect completely. You may need to add a disinfecting agent to the tank, or even use an autoclave. Check your organization’s requirements for instrument cleaning to be sure you comply.
  4. Run the tank for five to ten minutes with nothing in the tank but your solution. This will assist the heater in reaching the desired temperature, and will also “de-gas” the solution. De-gassing is a process whereby trapped air in your cleaning solution is driven out by ultrasonic activity. This is necessary because until this gas is cleared, some of the energy will be wasted on this instead of being used for cleaning. This can throw off your results, and give you an incorrect indication of the required cleaning time.
  5. Lower instruments, or racks of instruments, into the tank. You will need to use a basket or a support rack. You cannot set parts on the bottom of an ultrasonic tank, as that is where the transducers are located. In any event, using a basket makes getting clean (and hot!) parts a lot easier to get out of the tank. Set temperature, power, and cleaning time to desired parameters. Start with 3 minutes at 155F and see where that leaves you. If you still do not meet requirements, increase the cycle time and / or temperature. Note that after 20 minutes, little additional cleaning will take place.
  6. Record your results! Always strive to develop the cleaning process that takes the least time, heat and cleaning solution concentration. This will make your process as effective and economical as it can be while still meeting spec. Some experimentation is in order.
  7. At the end of the cycle, remove instruments from the tank, dry with high temperature filtered compressed air if available. Air drying is fine as well.
