Lab Ultrasonic Cleaner Features Uniform Sonication

Uniform sonication, or perfect sound field distribution, a desirable feature for ultrasonic cleaners used in analytical and medical laboratories as well as other professional settings, is achieved in the multi-functional Elmasonic P30SE available from Tovatech.  Uniform sonication assures users that instruments and lab samples in flasks or beakers receive “equal treatment” regardless of their position in the tank.   

The Secret to Uniform Sonication

Elma researchers determined that the 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: cavitation in a beaker suspended on the drain side of the tank was not nearly as vigorous as in the beaker on the opposite side.  Based on this the 0.75 gallon P30SE has no drain and demonstrates homogeneous sonication.*

A Highly Versatile Lab Ultrasonic Cleaner

Elmasonic P30SE

The dual range 37/80 kHz frequency Elma P30SE allows users to select the lower frequency for more vigorous cleaning, mixing, dissolving and degassing tasks.  Select 80 kHz for cleaning delicate capillaries, highly finished surfaces or for longer cleaning cycles.  The unit allows users to program an automatic 30-second frequency switch-over for simultaneous coarse and fine cleaning.

Other Useful Features and Benefits

Housed in an attractive, easily cleaned stainless steel case, the Elma P30SE offers these additional user-activated features allowing researchers to customize sample prep and cleaning processes:

  • Time and temperature settings with “set” and “actual” shown on the LED display
  • A normal mode for mixing, dissolving and dispersing
  • A pulse mode for intermittent high-intensity bursts to remove stubborn deposits
  • A sweep mode for uniform distribution of cavitation action throughout the tank. (Note that Sweep enhances top-to-bottom uniformity of cavitation in the tank; eliminating the drain enhances side-to-side uniform sonication.)
  • A degas mode to remove air from new solutions, HPLC samples and solvents
  • Adjustable ultrasonic power to match to sensitive surfaces
  • A pause function to examine or remove bath contents
  • Auto-start to initiate uniform sonication when the set bath temperature is reached
  • An automatic switch-off after 12 hours of continuous operation or if the bath reaches 90⁰C (194⁰F)

These and other features are accessed and activated via the comprehensive control panel on the P series of ultrasonic cleaners.   Set and actual parameters are shown on the control panel digital display.

About Rachel Kohn

So how did an MIT Ph.D. end up selling refrigerators? When I figured out that a lot more scientists buy lab refrigerators than innovative leading-edge instruments. I hope that my many years of lab experience will help you find the right equipment for your work. Before co-founding Tovatech I worked in business development and project management at Smiths Detection, Photon-X, Cardinal Health, and Hoechst Celanese. And before that I spent 12 years as an R&D chemist at Hoechst Celanese and Aventis working on advanced drug delivery systems, polymer films and membranes, optical disks, and polysaccharides. Some day, eventually, I’ll make enough money to develop an innovative technology that will change the world. Read More
