Ultrasonic Cleaner Capacity Selection Tips

One of the first if not the first point in selecting an ultrasonic cleaner is the ultrasonic cleaner capacity.  By capacity we mean not the size of the ultrasonic cleaner itself but the size, or dimensions, of the cleaning tank. That’s where cleaning action takes place.  If the parts you want to clean can’t be completely immersed in the ultrasonic cleaning solution, you have a problem.  This post helps you calculate your ultrasonic cleaner capacity.

Two Basic Approaches to Ultrasonic Cleaner Capacity

You can specify an ultrasonic cleaner in terms of cleaning solution capacity or its ability to completely immerse parts being cleaned.  A simple illustration:  There’s not much depth to a gallon of water in an 8 quart baking pan.   Contrast that depth to a gallon of water in a gallon water jug.

With that in mind, let’s proceed.

Fortunately, ultrasonic cleaners are manufactured in a tremendous variety of sizes.  And as suggested, there are two approaches to sizes when speaking in terms of ultrasonic cleaner capacity.

First, “size” can be defined in terms of the tank’s cleaning solution capacity.  Second, “size” can be defined in terms of tank dimensions, or its ability to accommodate parts being cleaned.

As you can see by checking our page on the Elmasonic E Plus series, there is a selection 9 tank capacities from 0.25 to 7.5 gallons, all with differing tank dimensions, offered in this series.  Industrial-sized units such as the xtra ST series can hold up to 67.4 gallons.  Larger-capacity units are also available.

Sample Preparation in an Ultrasonic Bath

Sample Preparation in an Ultrasonic Bath

Sample preparation to transform analytes into measurable form can involve complex processes. It is important that the transformation or extraction process avoids chemical degradation that can be caused by excessive heat or mechanically induced damage. Sample preparation is defined by the International Union of Pure and Applied Chemistry (IUPAC) as the process used to transform analytes into a measurable form.

Ultrasonic Cleaning Solution Selection Tips

You are using, or are considering using, an ultrasonic cleaner to handle your critical cleaning operations.  You want to select the best ultrasonic cleaning solution, or cleaning chemistry, to do the job quickly, thoroughly and efficiently. This post will help you select the ultrasonic cleaning solution(s) to handle your projects.

The Ultrasonic Cleaning Solution Market

According to an article in Science Direct, “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.”  The broad acceptance of ultrasonic cleaning technology is matched by a similar broad increase in the selection of ultrasonic cleaning chemicals.  According to a Dataintelo report “The ultrasonic cleaning chemicals market was valued at USD 2.1 billion in 2018.  The report projects a “CAGR of 4.4% during 2019-2030.”

Why you Need an Ultrasonic Dental Cleaner

Ultrasonic Dental Instrument Cleaner with Uniform Sonication

An ultrasonic cleaner is one of options recommended by the CDC to clean reusable dental instruments prior to sterilizing. Uniform sonication in an ultrasonic dental instrument cleaner provides added assurances that blood and tissues are thoroughly removed before sterilization. More on this below but first,

How Uniform Sonication Cleans Dental Instruments

Uniform sonication assures technicians in the central processing area that their dental instruments receive “equal treatment” regardless of their position in the ultrasonic cleaning bath.  An example of a dental instrument cleaner providing this advantage is the Elmasonic P30SE available from Elma. 

Research at Elma disclosed that key impediment to uniform sonication is interference due to the tank drain duct found on most benchtop ultrasonic cleaners.  This was visually demonstrated in a drain-equipped unit: ultrasonic cleaning action on the drain side of the tank was not nearly as vigorous as on the opposite side. 

Based on this, the 0.75 gallon P30SE has no drain assuring that powerful cleaning action on reusable dental instruments is uniform during the cleaning cycle.  The process is called homogeneous sonication.

Maintain Plastic Injection Molds with Ultrasonic Cleaning

Injection Mold Maintenance Tips

According to a blog post by Rex Plastics, “A small and simple single cavity plastic injection mold usually costs between $1,000 and $5,000. Very large or complex molds may cost as much as $80,000 or more. On average, a typical mold that produces a relatively simple part small enough to hold in your hand costs around $12,000.”

For cost reasons alone injection mold maintenance should figure high on a list of priorities for companies involved in producing injection-molded parts.  This post describes how the power of ultrasonic cleaning preserves investments in costly injection molds without causing wear or the use of harsh chemicals

An Industrial Ultrasonic Cleaner Specification Guide

The ultrasonic cleaning equipment market is expected to exhibit a 3.3% CAGR by 2027 backed by increasing global adoption of industry 4.0 (the 4th Industrial Revolution), according to a report in  Fortune Business Insights™  “Industrial Ultrasonic Cleaning Machine Market” 2022 focuses on short-term and long-term trends affecting the market landscape.  Industrial ultrasonic cleaners play an important role in the economy.  This post will help you pick a unit that best meets your requirements.

What is an “Industrial” Ultrasonic Cleaner?

Industrial ultrasonic cleaners are defined by task, not size.  Industrial sonic cleaners include bench and tabletop units all the way up to multi-gallon floor mounted units. 

It’s what these units must do vs. their size that’s important.  So let’s begin our specification guide.

When to Specify an Industrial Ultrasonic Cleaner

To start with industrial ultrasonic cleaners are employed for tough and often long-term cleaning cycles.  These units may be required to continuously operate for hours and must be designed to meet these rigorous operating conditions.

Here’s a start on points to consider:

Ultrasonic Cleaning to Remove 3D Printing Mold Support

Use Ultrasonic Energy to Remove 3D Printing Mold Support

Ultrasonic cleaning is fast and safe way to remove mold support and other surface contaminants from simple and complex 3-D printed parts.  Results are far superior to time-consuming water soaking and the risk of possibly damaging part geometries if manually cleaned using brushes.  Here you’ll learn how 3-D printed parts are made, then how ultrasonic energy is used to remove 3D printing mold support from your parts.

How 3-D Printed Parts are Made

3D part printing techniques use a variety of plastics and resins.  Examples include ABS, PLA, polyamide (nylon), glass filled polyamide, stereolithography materials (epoxy resins), silver, titanium, steel, wax, photopolymers and polycarbonate.   

A popular technique combines two moldable thermoplastic formulations such as ABS for the part itself and PLA for removable mold support.  This is a quick means to produce highly complex configurations.

In this instance a key to the efficiency of the process is fast, safe removal of the PLA mold support without risking damage to the ABS part.  An ultrasonic cleaner is proven far faster, safer and more effective than water sprays or manual scrubbing.

Other techniques called SLA (stereolithography) and LFS (low force stereolithography) use lasers to build the part without the need of mold support. In these cases uncured resin on the finished product requires removal best accomplished by ultrasonic energy.

How Can I Use Flammable Solvents in an Ultrasonic Cleaner?

First, let us congratulate you for asking this question.  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 post explains how you can safely use flammable solvents in an ultrasonic cleaner.    

An example of a widely used flammable solvent is isopropyl alcohol (IPA).  References to its use are presented in this post.

Things to Know about Flammable Solvents and Ultrasonic Cleaners

Before you select and use an ultrasonic cleaner for your application(s) you should be familiar with options available as well as other factors that go into the decision process.  Here you will learn about
