Using Industrial Ultrasonic Cleaners to Effectively Clean Laboratory Instruments

November 29, 2016

Industrial Ultrasonic Cleaners for Laboratory InstrumentsIndustrial ultrasonic cleaners are widely used in industry to clean parts and components rapidly and effectively. The systems outperform conventional cleaning methods and reduce the use of chemicals and other consumables. Ultrasonic technology represents an advanced cleaning solution that can remove contaminants from a variety of materials and that can be adjusted to deliver robust or delicate cleaning action. As such, ultrasonic cleaning systems are ideally suited for cleaning instruments in the lab.

How Ultrasonic Technology Cleans Instruments

Ultrasonic cleaning systems are made up of ultrasonic generators, transducers and cleaning tanks or containers. The generators produce the ultrasonic signal and the transducers change the signal into ultrasonic waves in the cleaning liquid. The waves produce the microscopic cavitation bubbles responsible for cleaning action in the cleaning solution.

As an ultrasonic wave passes through the liquid, it generates bubbles between the compression peaks and collapses the bubbles within the peaks. This creation and collapsing of tiny bubbles produces an intense scrubbing action that removes contaminants from the lab instrument surfaces.

Low frequencies produce larger bubbles and more robust cleaning action while high frequencies have smaller bubbles for a more gentle cleaning of delicate instruments. If a variety of lab instruments have to be cleaned, the ultrasonic system frequency can be adjusted to suit the particular cleaning application.

Advantages in the Laboratory

Ultrasonic cleaning is an advanced cleaning solution that works quickly, cleans completely and is environmentally friendly. Conventional mechanical washing and cleaning with solvents is slow and often leaves a residue. The disposal of non-biodegradable solvents may pose difficulties and the washing process may damage delicate instruments. Ultrasonic cleaning addresses all these issues effectively.

Tabletop turnkey systems are easy to use and are often large enough for lab use. The bubble action can be adjusted to remove contaminants and leave the surface of the instrument clean but unaffected. The ultrasonic waves clean odd shapes, holes and hard-to-reach places easily because the bubbles penetrate wherever there is liquid. Industrial ultrasonic cleaners work in water but can clean more rapidly if mild solvents are added. In either case, cleaning is quicker than with conventional methods.

Kaijo Phenix III Turnkey Ultrasonic Cleaning System

The Kaijo Phenix III turnkey ultrasonic cleaner is a cost-effective solution for general purpose cleaning of laboratory instruments. It operates at 26 kHz or 38 kHz and is made up of an ultrasonic generator and a stainless steel tank with an integrated transducer. It is ideal for cleaning material made of glass, porcelain, ceramics, plastics, and metals and can deliver up to 1200 W.

The generator measures about 14 x 18 inches and is about 6.5 inches high. Available tanks measure from 14 to 22 inches long, 10 to 20 inches wide and up to 18 inches high. As a result, the unit can be used on a desktop or a lab bench. Inside dimensions of the tank are slightly less but the tanks can all accommodate instruments of 12 to 18 inches long.

Kaijo’s Quava Mini Industrial Ultrasonic Cleaner

The Quava Mini is a smaller but more versatile ultrasonic system that can produce frequencies from 26 kHz to 160 kHz at a variable power of up to 100 W. The tanks are approximately 6-inch cubes with inside dimensions of about 4 x 4 x 6 inches. With its small size and range of frequencies, the Quava Mini is ideal for a wide variety of cleaning jobs including the cleaning of small and delicate lab instruments at higher frequencies for gentle cleaning action.

In addition to these two turnkey systems, Kaijo offers a range of ultrasonic cleaning equipment and can help laboratories select the systems or components that best meet their needs. Kaijo’s ultrasonic cleaners can help laboratories with cleaning solutions that are convenient, save time and deliver improved cleaning performance.

7 Reasons to Clean Using the Power of Ultrasonic Cleaning Systems

November 16, 2016

7 Reasons to Clean Using the Power of Ultrasonic Cleaning SystemsUltrasonic cleaning systems can provide quick, efficient and effective cleaning of a variety of parts and equipment without the use of chemicals or mechanical action. As a result, companies that use these systems increase productivity and process throughput while reducing the use of consumables. Below are seven reasons for using ultrasonic cleaning systems and the details of why they are superior in each case.

  1. Ultrasonic cleaning systems deliver improved cleaning performance.

Ultrasonic transducers generate microscopic bubbles whose collapse creates an intensive scrubbing action throughout the cleaning solution. The bubbles act around corners, in crevices and through holes to clean parts and equipment of all shapes and sizes. By adjusting the ultrasonic frequency and the power, the cleaning action of the bubbles can be adjusted in intensity to match the particular cleaning requirements. Contaminants and foreign material are removed quickly and completely.

  1. Parts and equipment are cleaned faster.

Cleaning with chemicals is slow as the parts and equipment to be cleaned have to soak in the cleaning solution that subsequently has to be neutralized. Additional mechanical scrubbing is often required and the times between batches are substantial because of the time required to change and set up the chemical baths. Ultrasonic cleaning uses only water and occasionally a mild solvent for even the most challenging cleaning tasks. Cleaning can take as little as a few minutes and rarely over two hours.

  1. Ultrasonic cleaning removes contaminants without damaging parts and equipment to be cleaned.

Cleaning processes that use blasting, scrubbing or harsh chemicals can cause damage such as pitting, scratching and bending in the material to be cleaned. Ultrasonic cleaning systems can adjust the frequency to deliver the cleaning intensity required. Lower frequencies have larger bubbles with more robust cleaning action while higher frequencies provide more gentle cleaning. The frequencies used can be fine tuned to remove dirt while leaving the underlying surfaces unaffected.

  1. Ultrasonic cleaning systems are environmentally friendly.

Unlike traditional cleaning methods that often use harsh chemicals to remove stubborn contamination, ultrasonic cleaning systems operate in water or in a solution containing mild solvents. Chemicals have to be stored, handled, mixed, used and neutralized. Even when treated they are not benign when discharged and accidents during storage, handling and use are always possible. These environmental threats and pollution do not exist with ultrasonic systems.

  1. Ultrasonic technology is safer for workers.

Many chemical cleaning processes use materials that are hazardous and cleaning techniques such as water blasting also have safety issues. Operator errors can put personnel at risk and accidents can have severe consequences. Ultrasonic technology is safe and has no hazardous components, materials or processes. Risk to personnel from errors or accidents is much lower than for conventional cleaning systems.

  1. Ultrasonic cleaners have a higher capacity than conventional systems.

Once installed and set up, ultrasonic cleaning tanks and containers can clean parts and equipment almost continuously without down time. Material to be cleaned can be placed in the cleaning tanks and ultrasonic cleaning can begin immediately. Cleaning is rapid and thorough. When the material is clean, it can be removed and the next batch of cleaning can be started. The cleaning process itself is faster and throughput is higher than with conventional cleaning systems.

  1. Ultrasonic systems are versatile and can handle a variety of applications.

Ultrasonic systems consist of ultrasonic generators, transducers and the cleaning tanks. Multiple high-powered transducers can be configured in very large tanks to handle the ultrasonic cleaning of large equipment. Low frequencies deliver robust cleaning for such applications. At the other end of the scale, single transducers can be mounted in small tanks to clean a variety of parts and high frequencies can be used to clean delicate components. Ultrasonic cleaning systems can provide the many different cleaning tasks required for industrial plants using heavy equipment.

Kaijo’s ultrasonic cleaning systems deliver cleaning performance that validates the above 7 reasons for using ultrasonic cleaning. The company can evaluate the cleaning needs of industrial customers including those need heavy equipment applications and deliver corresponding solutions.
