How to Select an Ultrasonic Cleaning Solution

ultrasonic_cleaing_solution_selection_v3Benchtop and industrial ultrasonic cleaners provide outstanding cleaning results in thoroughness and speed for applications from watch making to jet engine components and virtually anything in between that can be safely wetted.  Largely responsible for this is the variety of ultrasonic cleaning solutions provided by manufactures to target both broadly defined and highly targeted cleaning challenges. Selecting the right ultrasonic cleaning fluid is not a hit-or-miss proposition.  Several considerations come into play.  

Ultrasonic Cleaning Solution Selection Tip No.1

What is the contaminant?  Put another way, what do you want to remove by an ultrasonic cleaning process?  Examples include

  • grease, grime and grit on engine and drive train components
  • salt and other residues on scuba gear
  • soldering residues and other contaminants on PCBs
  • burned on plastic injection mold deposits
  • grit and grime on cherished vinyl LP records
  • contaminants on surgical and dental instruments
  • tarnish or old paint on brass, copper and

Solving Tough Cleaning Challenges with Ultrasonic Cleaning

Ultrasonic Cleaning Solutions

According to a report available from market research firm IBIS World, “in 2016, the ultrasonic cleaning equipment manufacturing industry is expected to generate $359.6 million in revenue,” and, “over the five years to 2016, industry revenue increased at an annualized rate of 1.8%, including an expected 3.7% rise in 2016.”*

At Tovatech we believe that this positive projection is due in part to the continuing and growing realization that tough cleaning challenges can be overcome with ultrasonic energy.  Many of our posts go into detail on the use of ultrasonic energy to solve cleaning challenges.  We present here a compendium of applications that may or may not be top of mind to folks grappling with difficult cleaning challenges.… Read the rest

Selection and Operating Tips for Ultrasonic Cleaners

How to Select an Ultrasonic Cleaner

How you select an ultrasonic cleaner involves several points to consider and resolve before putting your money down.  Today’s ultrasonic cleaners range from small benchtop or tabletop units with simple on-off switches to highly sophisticated cleaners with adjustable or controllable operating parameters that allow them to perform multiple cleaning tasks.  Cleaning solution capacities can range from under one gallon for household or hobbyist applications to hundreds of gallons capable of cleaning automotive, marine and aircraft engines.

Cleaning solution chemistries as well are available in many, many formulations and should be carefully selected (and maintained) to provide optimum cleaning performance based on what is being cleaned and the nature of contaminants being removed.  Most of today’s popular ultrasonic cleaning solution formulations are available as water-based concentrates and are biodegradable.  These two features provide economies, simplify storage and reduce, if not eliminate, disposal concerns.  The problems and challenges associated with trichloroethylene and … Read the rest

How to Safely Clean Fine Mesh Sieves

SRH 4/200 sieve holder on drain tray/lid

Safely cleaning fine mesh sieves means quickly and thoroughly removing trapped particles without damaging or deforming the sieve mesh.   Manual cleaning using brushes to dislodge particles has drawbacks that include potential damage to fine mesh and failure to achieve 100% particle removal.  The problem is solved by combining the Elma SRH 4/200 rotating sieve holder with a 37 kHz 7.5 gallon Elmasonic E 300H or S 300H ultrasonic cleaner*, all available from Tovatech.

 

Clean Four Sieves Simultaneously

The electrically powered SRH 4/200 module holds up to 4, 200-mm (8 inch) lab sieves clamped in a slightly canted position and rotates them into and out of the ultrasonic cleaning solution. Ultrasonic cavitation produced by the E or S 300H generator-powered transducers creates billions of minute bubbles that implode vigorously against the screen mesh to quickly but safely dislodge trapped particles.  Because the screens … Read the rest

How to Prepare Samples Rapidly and Safely

Use the S150 ultrasonic cleaner for sample prep and cleaning lab ware

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.

Ultrasonic energy is a proven technique to achieve fast, safe sample preparation.  As an example it is a method often specified in USP monographs to extract active pharmaceutical ingredients from carriers for content uniformity and potency assay tests. The ultrasonic process is also ideal for dissolving, dispersing, emulsifying, homogenizing and mixing.

Sample Preparation Steps

Samples to be analyzed are placed in flasks along with a recommended solvent.  Flasks are partially immersed in a sonicator bath containing a surfactant.   The 37 kHz Elmasonic S150 ultrasonic bath available from Tovatech is especially designed to quickly and safely accomplish sample preparation.  The inside dimensions of the … Read the rest

Tips on Selecting Ultrasonic Cleaner Size

Consider tank dimensions, basket dimensions and fill lines when specifying ultrasonic cleaners

Consider tank dimensions, basket dimensions and fill lines when specifying ultrasonic cleaners

A number of calculations must be considered when contemplating acquiring an ultrasonic cleaner. Ranking at or near the top of the list is the ultrasonic cleaner size. A seemingly natural starting point would be to specify a cleaning tank based on its internal dimensions against the full dimensions of the part to be cleaned.

This is not always a good idea.

First consider what is called the “working depth” of the cleaner and the fact that baskets holding products being cleaned have smaller dimensions than tank internal dimensions.

Working depth is defined as the distance between the bottom of cleaning basket and the surface of the cleaning solution. This is because products being cleaned must be fully immersed in the solution.

Tank internal dimensions and basket dimensions are provided by ultrasonic cleaner manufacturers. An example is the 2.5 … Read the rest

It’s Outdoor Power Equipment Tune-up Time

Ultrasonic engine cleaning extends the life of outdoor power equipment

Ultrasonic engine cleaning extends the life of outdoor power equipment

Thinking about tuning up outdoor power equipment may seem a bit farfetched in mid-winter. But many small engine repair shop operators will be quick to agree that getting outdoor power equipment ready now will help avoid a long wait when spring arrives and you need your mowers and garden tractors ready now, not in two weeks! That’s why ultrasonic cleaners are the best friend of small engine repair shops and professional landscaping and lawn care service providers.

Why Ultrasonic Cleaners Work Best

When cleaning and tuning up outdoor power equipment speed and thoroughness are keys to fast turnaround and excellent results. Carburetors especially but all small engine components are subject to accumulations of varnish, gum and carbon deposits as well as soil grit and other contaminants that both reduce engine efficiency and increase wear. Aerosol sprays or brushing with potentially … Read the rest

A Prescription for Cleaning Vinyl Records

Cleaning vinyl records is emerging as a cottage industry for individual collectors such as Gerry from Spring Hill, Florida, who has amassed an impressive collection of 4500 LPs and 45s; for record collection clubs, and for retail outlets selling new discs or used old vinyl. To many of these aficionados vinyl record sound quality is far superior to that delivered by CDs. For maintaining (or restoring) this sound quality, according to Gerry, nothing beats a small benchtop ultrasonic cleaner paired with a mechanism that rotates the records into and out of the cleaning solution where ultrasonic cavitation safely, quickly and completely removes dust and other quality-inhibiting contaminants from the grooves.

Gerry’s Prescription for Cleaning Vinyl Records

“Ultrasonic cleaning, in my opinion, takes record cleaning to the next level as follow-on to my vacuum record cleaning equipment,” Gerry says. “I use the … Read the rest

How to Quickly Clean MX and ATV Bike Engine Parts

Sonic cleaning helps maintain ATV engine and drive components

Sonic cleaning helps maintain ATV engine and drive components

Messy, time consuming manual cleaning MX and ATV quad bike engine, drive and suspension parts is unnecessary when an ultrasonic cleaner replaces scrubbing with solvents in wash tanks. Cycle service shops as well as MX and ATV clubs can put the power of ultrasound to work to speed throughput and preserve investments in off-road sports equipment.

Ultrasonically cleaning MX and ATV bike parts is faster than manual methods for two reasons:

  1. Many components do not have to be completely disassembled, but simply immersed in a biodegradable ultrasonic cleaning solution.
  2. It is thorough because sonic cleaning action removes road dirt, grease, grime, varnish, carbon deposits and other contaminants. Cleaning reaches the tiniest and most inaccessible grooves and blind holes in engine and suspension components – in short all surfaces immersed in the cleaning solution.
