Ultrasonic cleaning units in six different sizes. Digital displays, self-explanatory operation, clear indication of all parameters, set and actual values at a glance. Two different ultrasonic frequencies in one unit (frequency can be changed during operation): - 37 kHz: for coarse contaminations, for dissolving, blending, dispersing and degassing. - 80 kHz: noise-reduced operation, ideal for quiet work areas, prolonged ultrasonic cleaning cycle, perfect for the cleaning of hollow spaces, e. g. capillaries. - Elmasonic P 30 SE without drain duct.
