Your laboratory must be a completely clean, sterile and organized area. It is important that you own the right items, especially the ones that take care of the cleaning process, in order to have reliable results. Ultrasonic baths are one of these items. These devices work as an ultrasonic cleaning process, using ultrasound an appropriate cleaning solvent that can occasionally be tap water, in order to clean items. This last factor enhances the cleaning effect, so it is an aspect you must keep into consideration.
The ultrasonic baths work by cavitation bubbles induced by high frequency pressure (sound) waves to agitate a liquid. The agitation produces high forces on contaminants adhering to substrates like metals, plastics, glass and rubber. This action also penetrates blind holes, cracks, and recesses. The intention is to thoroughly remove all traces of contamination tightly adhering or embedded onto solid surfaces. Contaminants can include dust, dirt, oil, pigments, rust, grease, algae, fungus, bacteria, lime scale, polishing compounds, flux agents, fingerprints, soot wax and mold release agents, biological soil like blood, among others.
Using Ultrasonic Cleaners (Ultrasonic Baths)
In an ultrasonic cleaner, the object you need to clean is placed in a chamber containing a suitable solution. An ultrasound generating transducer built into the chamber, or lowered into the fluid, produces ultrasonic waves in the fluid by changing size in concert with an electrical signal oscillating at ultrasonic frequency. Most hard, non-absorbent materials (metals, plastics, etc.) not chemically attacked by the cleaning fluid are suitable for ultrasonic cleaning.
One of the most important things to keep in mind is that ultrasonic baths does not sterilize the objects being cleaned, because spores and viruses will remain on the objects after cleaning. In medical applications, sterilization normally follows ultrasonic cleaning as a separate step. However, ultrasonic baths will provide you with a number of benefits that are not available with other styles of industrial parts washers. As parts get smaller and more intricate, ultrasonic cleaners become the “parts cleaner of choice.”
Having an ultrasonic bath can be a time saving strategy inside your laboratory, since the ultrasonic cleaners can emit up to 40 thousand sound pulses per second and each pulse provides cleaning action as it influences the part’s surface. Because of this high-frequency wave action, ultrasonic cleaners can remove contaminants faster and better than other types of cleaners. In addition, these devices can remove a wide variety of contaminants from a part’s surface, including oil, grease, wax, shavings, dirt, dust, clay, sand, parting compound, soot, carbon, and oxidation, down to a microscopic particle size. No other parts cleaning system offers that level of flexibility in the same unit.
Advantages of the Ultasonic Baths for Cleaning Processes
Ultrasonic baths stand out when it comes to cleaning complex parts. Because the cleaning detergent or water and high frequency waves can penetrate all surfaces, even hidden passageways, narrow openings, crevices, cracks, and blind-drilled holes get just as clean as the visible surfaces without the intense hand-cleaning costs. Another aspect you must keep into consideration is the fact that ultrasonic baths have a lower power consumption than the rest of cleaning devices. Compared to other types of parts-cleaning systems that use a variety of motors to pump, spray, circulate, agitate, and capture the cleaning chemical and its vapors, ultrasonic cleaners need only one small motor to filter the solution. The rest of the cleaning is done with efficient electrical energy and transducers, keeping power consumption to a minimum.
In conclusion, if you are thinking about purchasing ultrasonic baths, you must certainly get them. They seem to be the best part cleaner option giving you practical features such as quality, practicality, efficiency and a smaller footprint.
