As many researchers have found there can be some real challenges in dissolving or mixing samples in the lab. Technicians in healthcare facilities know that cleaning medical instruments prior to disinfecting and sterilizing also requires care to be certain that blood and tissue are completely removed, even from small cracks and crevices.
Ultrasonic cavitation can solve both challenges, and a new ultrasonic cleaner just released by Elma does it in a big way in a small package. Delivering 300 watts average ultrasonic power and available from Tovatech the microprocessor-controlled Elma S150 ultrasonic cleaner operates at 37 kHz and has a capacity of 3.75 gallons of solution in a 20” x 12” x 4” deep tank. It is the shallow depth that accounts for the high ultrasonic power per unit volume.
Lab researchers put the S150 ultrasonic cleaner to work in emulsifying, dispersing, dissolving or mixing difficult samples and degassing HPLC samples. Because flasks containing these samples do not need to be fully immersed, several can be placed in the ultrasonic cleaner’s mesh-bottom tray for simultaneous processing.
Cleaning medical instruments used in healthcare facilities is accomplished quickly and safely with the Elma S150. Its powerful cavitation action removes blood and tissue before the ultrasonic cleaning solution reaches a temperature that causes them to bake onto surfaces. In this application instruments are placed in the tray and fully immersed.
Processing cycles for this ultrasonic cleaner can be set from 1 to 30 minutes with set time and remaining time shown on an LED display. Fresh ultrasonic cleaning fluids are automatically degassed, while maximum cavitation action is delivered by the S150 sweep function.
