Large Ultrasonic Cleaner Selection

Large Ultrasonic Cleaner Selection

A large ultrasonic cleaner is a close cousin to an industrial ultrasonic cleaner but is selected to clean (you guessed it!) large parts.  Or a large number of parts in the same cycle.  An obvious characteristic of large ultrasonic cleaners is cleaning tank dimensions (and therefore cleaning solution capacity) to accommodate the parts, either in size or number, that you need to clean.  We invite you to read this post for other important considerations in selecting a large ultrasonic cleaner.

If you’re not familiar with the power and versatility of ultrasonic cleaners, please take a few moments to review the 10 Tips for Selecting the Best Ultrasonic Cleaner.… Read the rest

The Ultimate Industrial Ultrasonic Cleaner Guide: How to Select the Right Industrial Ultrasonic Cleaner

How to Select an Industrial Ultrasonic Cleaner

Industrial ultrasonic cleaners come in many sizes, shapes and features.  This guide will help you pick the equipment right for you. 

What is an “Industrial” Ultrasonic Cleaner?

You might think an industrial ultrasonic cleaner must be “big” because it is handling industrial products.  Not necessarily so.  Your industrial parts washer size (or cleaning solution capacity) is governed by the size of parts you are cleaning.  They are offered as benchtop and floor mounted models. 

Another consideration to keep in mind is the duration of your cleaning cycles.  Long-term cleaning cycles (i.e. operating continuously over a work shift) mean your unit should have a heavy-duty tank to prolong service life.

An example is the heavy-duty, Elma xtra TT series benchtop industrial ultrasonic cleaner with tank sizes from 0.79 to … Read the rest

The Ultimate Guide for How Ultrasonic Cleaning Works

How Ultrasonic Cleaning Works - The Ultimate Guide

In Ultrasonic Cleaning, an Historical Perspective, author Timothy J. Mason notes “The development of ultrasonic cleaning dates from the middle of the 20th century and has become a method of choice for a range of surface cleaning operations.” This helps explain why, according to a Fortune Business Insights report, “the global ultrasonic cleaning equipment market was $604.8 million and projected to reach $783.1 million by 2027.”

The Basics of Ultrasonic Cleaning

A way to describe how ultrasonic cleaners work is likening them to an automatic dishwasher, but with some added refinements.  An automatic dishwasher, much the same as an ultrasonic cleaner, combines water and a detergent to remove grease, grime and other contaminants from objects being cleaned. 

But instead of cleaning pots and pans and … Read the rest

The Ultimate Resource for Ultrasonic Cleaning with Flammable Solvents

How Can I Use Flammable Solvents in an Ultrasonic Cleaner?

Examples of a widely used flammable solvents are IPA (Isopropyl alcohol), Acetone, and IMS (Industrial Methylated Spirits). Any time flammable solvents are used for cleaning purposes there is risk of fire or explosion due to ignition of volatile vapors by a flash source. Ignition can occur from any source due to spills or as flammable solvent vapors spread. This guide will explain how you can safely use flammable solvents in an ultrasonic cleaner.

You may not have to use a flammable solvent as your cleaning solution. Watch the video below for details on selection a cleaning solution for your ultrasonic cleaner.

Cleaning with flammable solvents requires extreme caution in any case but ultrasonic cleaning with … Read the rest

Ultrasonic Cleaning with Flammable Solvents

ultrasonic cleaning using flammable solvent

Cleaning with flammable solvents requires extreme caution in any case but ultrasonic cleaning with flammable solvents requires specially designed equipment and procedures.  That’s because of the real danger of a fire or explosion if spilled solvent or vapors are ignited by sparks from internal electronics or external sources.  This post describes equipment to use and precautions to observe for ultrasonic cleaning with low flash point flammable solvents. 

But first, some explanations and relevant regulations.

What is a Flash Point?

Flammable solvents have different flashpoints. In brief, the lower the flashpoint the more flammable they are.  This is important when cleaning with flammable solvents.

Fortunately there is help.

The American Chemical Society publishes a table of common organic solvents that includes flash points.  Examples of low flash point volatile solvents are 1-propanol at 59⁰F (15⁰C), acetone at -4⁰F (-20⁰C)  and toluene at 39⁰F (4⁰C).

Ultrasonic Cleaner Solution Selection Tips

The ultrasonic cleaner solution you select plays a major role in successful ultrasonic cleaning operations. Ultrasonic cleaner solutions are available in a wide variety of formulations – each designed for specific cleaning tasks. These solutions are also referred to as cleaning chemistries and in some cases “soaps.” We’ll stick with ultrasonic cleaner solution in this post and provide you with tips on how to make the right selection.

How an Ultrasonic Cleaner Solution Works

ultrasonic_cleaing_solution_selection_v3

Regardless of the chemistry, an ultrasonic cleaner solution works by a process called cavitation.  This is defined as the implosion of millions of microscopic vacuum bubbles in an ultrasonic cleaner’s tank filled with the solution.  Bubbles are created by generator-powered transducers vibrating at ultrasonic frequencies such as 37,000 cycles per second (37 kHz). 

When bubbles contact products to be cleaned they implode violently (but safely) against all wetted surfaces to blast loose and carry away contaminants.

Ultrasonic Cleaner Uses

Elma Ultrasonic Cleaner for 3D Parts

An earlier Tovatech post on selecting an ultrasonic cleaner noted that the ultrasonic cleaner market is “expected to grow from USD 1.6 billion in 2019 to USD 2.2 billion by 2024, at a CAGR of 6.5%.” Much of this growth is due to the many ultrasonic cleaner uses that have evolved over the years.   

In this post we provide you with an overview of selected ultrasonic cleaner uses starting with a brief discussion of the ultrasonic cleaner process and why it works so well.

A Brief on the Ultrasonic Cleaner Process

6 Best Uses for Ultrasonic Cleaners

Ultrasonic cleaners use the power of cavitation – the violent implosion of billions of microscopic bubbles – to remove contaminants from any surface that can be safely immersed in biodegradable cleaning solutions formulated for specific cleaning tasks. 

Ultrasonic cavitation is created in an ultrasonic cleaner tank by generator-powered ultrasonic transducers bonded to the tank bottom.

Medical Ultrasonic Cleaner Performance Validation

OK-Sonic

In its “Guideline for Disinfection and Sterilization in Healthcare Facilities” the CDC notes “Ultrasonic cleaning removes soil by cavitation and implosion in which waves of acoustic energy are propagated in aqueous solutions to disrupt the bonds that hold particulate matter to surfaces.”

Sub-par performance of a medical ultrasonic cleaner could lead to trouble.  That’s because a number of factors can compromise the efficiency of these cleaners, leaving contaminants that might not be revealed by visual examination.   This is especially relevant when medical instruments and labware have complex, difficult-to clean configurations.  OK-Sonic™ medical ultrasonic cleaner performance validation strips provide added assurance that your ultrasonic cleaner is doing its job. … Read the rest

Ultrasonic Cleaner Machine: 10 Top Tips for Selecting the Best

An ultrasonic cleaner machine is often first choice for cleaning or processing operations across a broad spectrum of industry.  This is borne out by a comprehensive marketsandmarkets report predicting that the market 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.”

Why is this?

Ultrasonic cleaner machines are unsurpassed when it comes to removing contaminants from virtually any hard surface that can be safely immersed in a cleaning solution. 

They are also widely used in the pharmaceutical and other processing industries as sonicator baths because of their ability to disperse, mix and dissolve samples. 

The challenge is specifying your ultrasonic cleaner; its accessories, cleaning solution formulations, and cleaning procedures to accomplish tasks in the most efficient manner.
