According to Fortune Business Insights, the global cannabis market is projected to grow from $28.266 billion in 2021 to $197.74 billion in 2028 at a CAGR of 32.04% in forecast period, 2021-2028. These growth projections along with stringent regulations require the cannabis industry adopt proven methods to clean cannabis equipment. Ultrasonic energy is highly effective to remove gummy contaminants and other unwanted residues from cannabis processing glassware.
Cannabis Equipment Cleaning Challenges*
The cannabis distillation process can be called a “high-maintenance activity” because glass used in short path distillation is susceptible to being highly soiled with baked on and polymerized contaminants. The distillation process involves crude concentrates that are boiled until the desired components are distilled out, leaving behind unwanted residues.… Read the rest
Explosion-proof ultrasonic cleaners must be used when cleaning tasks call for the use of volatile solvents to achieve the desired results. See examples below. When low flash point flammable solvents are involved in an ultrasonic cleaning operation, a number of precautions are called for in addition to using an explosion-proof ultrasonic cleaner. This is because using these solvents creates what the NEC and NFPA term a hazardous location.
A flash point is the temperature at which a particular organic compound gives off sufficient vapor to ignite in air when given an ignition source. In view of this, selection of an ultrasonic cleaner must take into account that not only do volatile solvents evaporate, but the heat generated by the ultrasonic cleaning process accelerates solvent evaporation and vapor generation.… Read the rest
Selecting an ultrasonic cleaner for any cleaning and sample preparation operation requires careful consideration of many factors before making a purchasing decision. We offer useful guidelines in our post How to Pick the Best Ultrasonic Cleaner. This post focuses on two points in particular, frequency and power. Ultrasonic frequency is relatively easy to understand; understanding power is a bit more complicated. So let’s begin.
How to Specify Ultrasonic Frequency
Frequency is measured in thousands of cycles per second (kilohertz or kHz).
These frequencies are generated by transducers most commonly affixed to the bottom of the cleaning tank. Some ultrasonic units have transducers bonded to tank sides; others may have immersible transducers.
Wherever they are placed ultrasonic transducers are excited by the unit’s ultrasonic generator to produce millions of microscopic vacuum bubbles in the solution that implode on contact … Read the rest
Investments in firearms by individuals and organizations can be substantial. This post provides a comprehensive tutorial on how to maintain firearms with an ultrasonic cleaner. It offers you guidance on when and how to use gun cleaning solvents but focuses more on why an ultrasonic gun cleaner is a wise investment when maintaining firearms.
Gun Cleaning Solvents Described
Firearm owners may be aware of many gun cleaning “solvents” available on the market, but just what is a solvent? According to an article in Science Direct, a solvent can be defined as “a liquid that has the ability to dissolve, suspend, or extract other materials, without chemical change to the material or solvent.”
When it comes to maintaining firearms, gun cleaning solvents are generally employed just after a session on the shooting range or in the field. Savvy firearm owners recognize the importance of cleaning and lubricating their weapon … Read the rest
The worldwide acceptance of ultrasonic cleaning is confirmed by a MarketandMarkets report stating that it is expected to grow from USD 1.6 billion in 2019 to USD 2.2 billion by 2024, at a CAGR of 6.5% during the forecast period. That report describes reasons driving the growth rate while this post provides important tips on avoiding product damage by ultrasonic waves.
Ultrasonic Waves Described
Ultrasonic waves is another way of describing what is called cavitation action in an ultrasonic cleaner tank. Cavitation action results from the violent implosion of millions of microscopic bubbles every second.
These implosions create a temperature of 5000˚C (>9000˚F) and a jet of plasma impacting the objects being cleaned. It is cavitation action by ultrasonic waves that quickly strips away dirt and other contaminants from parts being cleaned.
Note that this action is exceedingly fast meaning it does not damage the parts. But over time it … Read the rest
An explosion-proof ultrasonic cleaning system satisfies customers’ preferences for flammable solvents employed during initial cleaning processes for new and reconditioned stainless-steel filters, reports Jeff Bernier, Quality Manager at Porvair Filtration Group in Caribou, ME.
“Solvent ultrasonic cleaning falls into our passivation cycle as a means of improving the corrosion resistance of our 316L stainless steel filters by removing ferrous contaminants like free iron from surfaces, and restoring them to their original corrosion specifications,” Mr. Bernier explains, adding “many of our chromatography customers expect it.”
Solvent Ultrasonic Cleaning Replaces Aqueous Solutions

“Our explosion-proof ultrasonic cleaner allows us to safely use flammable solvents versus previously employed non-flammable aqueous solutions for initial cleaning,” Mr. Bernier says.
“Grade A isopropanol alcohol and pharmaceutical grade acetone are the preferred solvents. However, they require specially designed ultrasonic cleaners as well as compliance with strict safety standards.
“These include the National Electric
Heavy parts degreasing engines and other heavy, complex machinery components can be accomplished quickly and effectively by cavitation action in industrial ultrasonic cleaners. This post provides guidance on the benefits of ultrasonic cleaning, how to use an industrial ultrasonic cleaner, and how to get the best performance from your industrial ultrasonic cleaning equipment.
Why Use an Industrial Ultrasonic Cleaner?
Cleaning and degreasing heavy parts can be accomplished several ways. Commonly used options include high-pressure steam cleaning and degreasing, solvent-based wash tanks and high-pressure sprays.
Common disadvantages of these options in addition to being time-consuming is that they are unable to penetrate and remove grease and other contaminants lodged in cracks, crevices and blind holes found in complex-shaped industrial parts.
As … Read the rest
Some states are adopting regulations requiring ultrasonic cleaning and sanitizing of tools used in hair salons and cosmetology salons. New Jersey, for example, requires a designated area for cleaning and disinfecting implements and tools, an ultrasonic cleaner for metal implements and tools, a clean, closed receptacle at each work station so soiled implements and tools can be completely immersed in an enzyme solution prior to cleaning and disinfection, and a clean, closed receptacle for storage of sanitized implements and tools at each work station.
Nothing surpasses an ultrasonic cleaner for removing dirt and contaminants from any equipment that can be safely immersed in water. Healthcare facilities have long relied on ultrasonic cleaners to remove blood and tissue from surgical instruments prior to disinfecting and sterilizing. A compact ultrasonic cleaner such as Elma’sE30H model available from Tovatech easily fits on a bench or tabletop in a designated cleaning area in a … Read the rest
