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):r- 37 kHz: for coarse contaminations, for dissolving, blending, dispersing and degassing.r- 80 kHz: noise-reduced operation, ideal for quiet work areas, prolonged ultrasonic cleaning cycle, perfect for the cleaning of hollow spaces, e. g. capillaries.r- Elmasonic P 30 SE without drain duct.rrFeatures: r- Normal: standard operation mode for laboratory applications such as blending, dissolving, dispersingr- Pulse: activatable power increase of approx. 20 % by inforcement of the peak performancer- Sweep: for an even distribution of the power in the cleaning tankr- Degas: for the quick degassing of HPLC samples or solventsr- Power control: for sensitive surfaces the ultrasonic power can be reduced in preset steps
