Degassing (deaeration, in the case of air) is the process of removing dissolved gasses and/or small entrained gas bubbles from a liquid. It is one of the most common applications of ISM's ultrasonic technology, which provides the means of removing the gasses from a variety of liquids, including water, candle waxes, polymers, epoxies, silicone oils, adhesives, coatings, beverages, inks, paints, transformer oils, emulsion and suspension products, motor oils and many more. Degassing can significantly contribute to the quality of the final product (fewer defects, improved aesthetics, etc.), making it a very desirable process for many companies.

In this blog post we demonstrate the processes of ultrasonic degassing and deaeration of a high-viscosity (17,500 cps) polymer oil, carried out in the batch mode.

When you need to replace a part in your LSP-500 or ship the processor to another location, you need to disassemble it first. In this post, we provide step-by-step disassembly instructions for the LSP-500 ultrasonic system configured in the flow-through mode. In addition, a link to a video on this topic is included at the end. 

Prior to disassembling the system, we recommend that you read the processor's manual. 

We are frquently asked for instructions on how to assemble and disassemble the LSP-500 laboratory-scale ultrasonic processor. In this blog post, we provide step-by-step assembly instructions that will help you get started with your LSP-500 configured in the flow-through mode. In addition, a link to a video on this topic is included at the end. In our next post, we will describe the disassembly steps for this processor.

Are you introducing ultrasound as a new technological solution for your liquid processing application? If so, some terms used in the ultrasonic industry may be unfamiliar. With this in mind, we are launching a series of blog posts that will cover the most common ultrasonic equipment and processing-related terminology.

This first post will focus on the terms used to describe the main components of an Industrial Sonomechanics (ISM) ultrasonic liquid processor and show you how these components work together. 

Many of us face the challenge of noisy work environment. In our previous blog post we talked about the noise produced by ultrasonic processors, which, if precautions are not taken, can be loud enough (up to 109 dBA) to cause significant discomfort and even lead to hearing loss. The details can be found at: How Loud is Your Ultrasonic Processor?

In most cases, a 20 - 25 dBA reduction in the ultrasonic equipment noise is sufficient for compliance with the U.S. and European occupational noise level regulations for an 8-hour work shift [1].  An additional reduction by approximately 5 - 10 dBA would bring the noise down to a background level for most industrial work environments. An ideal ultrasonic equipment noise reduction method would, therefore, attenuate sound levels by about 30 - 35 dBA across the audible frequency range.

The effect of operating an ultrasonic liquid processor (sonicator) on hearing is a question that arises often during discussions with our customers. The noise made by sonicators can be described as intense "hissing", which, if precautions are not taken, can be loud enough to cause significant discomfort or even lead to hearing loss. We performed a series of noise level measurements to determine how loud different types of ultrasonic processors really are.
