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.

Which is the purpose of this post.  But before digging into the 10 things you should know, … Read the rest

Choosing and Using an Ultrasonic Cleaner for Carburetors

Use an Ultrasonic Cleaner to Restore Carburetors

Fuel injection systems have replaced the carburetor but a Gili’s Automotive post states “While carburetors may not have a life in new vehicles today, chances are good that they’ll still be used for many years to come.”  That’s because “Carburetors, unlike fuel injection systems, are relatively straightforward when it comes to repairing them. Fuel injection requires sophisticated computers, but carburetors require only a screwdriver and a willingness to get one’s hands dirty.” Keeping carburetors clean is easy with an ultrasonic cleaner.

This post explains to shade tree and professional mechanics why ultrasonic cleaners for carburetors keep these vital assemblies (which were invented by Karl Benz in 1885) functioning. … Read the rest

How to Select an Eco-Friendly Ultrasonic Parts Cleaner

How to Develop an Eco-Friendly Metal Parts Cleaning System

Challenges relating to cleaning new or refurbished parts, many of which require subsequent processing such as painting and plating, are increasing due to environmental regulations.  This post shows you why an ultrasonic parts cleaner using eco-friendly biodegradable parts cleaning solutions is a favored alternate to washing and spraying with harsh solvents along with their associated disposal concerns.   

Why Choose an Ultrasonic Parts Cleaner?

Let’s start with why you should consider an ultrasonic parts cleaner.

Cleaning is faster, safer and easier when using an ultrasonic parts cleaner.  Machining oils, grease, residues left from molding or handling, soot and other contamination are difficult and can be dangerous to remove by soaking in harsh and sometimes flammable solvents, manually scrubbing or power washing in solvent parts washers. 

Moreover these methods do not reach difficult-to-access surfaces such as cracks, crevices, small diameter and blind holes where contaminants remain and can cause future problems.… Read the rest
