The fabric presented inward this department features models of ultrasonic cleaners that are unique to this manufacturer. Other sources’ equivalent models’ features should move considered for relevant applications.
Theory of Ultrasonic Cleaning
Everything that makes a audio vibrates, as well as everything that vibrates makes a sound; however, non all sounds are audible. Ultrasound literally agency beyond sound—sound beyond the audible spectrum. Considering 18,000 Hz (cycles per second) as an guess bound of human hearing, ultrasonics refers to audio above
18,000 Hz.
The ultrasonic ability render (generator) converts 50/60 Hz voltage to high frequency twenty or xl kHz (20,000/40,000 cycles per second) electrical energy. This electrical unloose energy is transmitted to the piezoelectric transducer inside the converter, where it is changed to high-frequency mechanical vibration. The noise from the converter are amplified past times the probe (horn), creating pressure level waves inward the liquid. This activity forms millions of microscopic bubbles (cavities) that expand during the negative pressure level excursion as well as implode violently during the positive excursion. It is this phenomenon, referred to as cavitation, that produces the powerful shearing activity at the probe tip, as well as causes the molecules inward the liquid to expire intensely agitated.
What are the differences betwixt an ultrasonic processor as well as an ultrasonic bath?
The intensity inside a john is fixed, low, location dependent, as well as inconsistent, due to the fluctuation inward the degree as well as temperature of the liquid. With an ultrasonic processor, processing is fast as well as highly reproducible. The unloose energy at the probe tip is high (at to the lowest degree fifty times that produced inward a bath), focused, as well as adjustable.
With ultrasonic processing, are at that spot whatever limitations?
Yes, viscosity, temperature, as well as liquid characteristics. The to a greater extent than glutinous the material, the to a greater extent than hard it is for the noise to move transmitted. Typically, the maximum viscosity at which a fabric tin move effectively
processed is 5000 cps. With measure systems the practical upper bound on temperature is roughly 150°C?Solid probes tin safely move used alongside both aqueous solutions as well as depression surface tension liquids (e.g., solvents); however, probes alongside replaceable tips should never move used alongside depression surface tension liquids.
Which musical instrument should I use?
The 400, 500, as well as 600 watt units are the close versatile because they tin procedure both large as well as pocket-size volumes—on a batch basis, as niggling as 200 mL alongside a microtip, or as much as ane L alongside a 1-in (25-mm) probe; on a flow-through basis, upward to 10 L/h. However, since every musical instrument volition perform every bit good upward to a sure as shooting volume, for samples upward to seventy mL the 70-watt unit of measurement is recommended, as well as the 130-watt unit of measurement for samples upward to 130 mL.
