Liquid Atomizer/Nebulizer operates at frequency of 1.6 MHz.
October 1, 2004 - Comprised of transducer and generator with 2 m connection cable, UM20-1.6 megahertz processor is suited for atomizing, nebulizing, fogging, and spraying of samples in analyzing processes. Ultrasonic device, designed for formation of aerosols, processes liquids of up to 500 cp at rates to 450 ml/hr. Droplet sizes down to 1 micron can be achieved without heat transfer. Operable in air, product has liquid feed supplied to oscillating sapphire glass surface.

Atomizing and Nebulizing Liquids by Megahertz Ultrasound
Atomizing, nebulizing, fogging and spraying of samples in pharmaceutical, biological, chemical and environmental analyzing processes are the domain of the new Hielscher UM20-1.6 megahertz processor. With the UM20-1.6 Hielscher offers a unique ultrasonic device for the formation of aerosols. It can process liquids of up to approx. 500cP at up to 450ml/hour. Using this megahertz device, droplet sizes down to 1 micron can be achieved without heat transfer. Different from spray nozzles or submersible transducers, small liquid volumes can be processed. As this megasonic processor can be operated in air, the liquid feed is supplied to the oscillating sapphire glass surface, where the megahertz vibrations atomize the liquid to micron-size particles. This effective cold atomizing can be used for example in spectroscopy analysis. This easy to operate ultrasonic processor consist of a transducer and a generator. The connection cable is 2m. It works at an operating frequency 1.6MHz ±15%. This makes the UM20-1.6 totally noiseless. The active, oscillating face is made of sapphire glass, quartz glass or other materials depending on the chemical corrosiveness of the medium. The UM20-1.6 is available as OEM-component for the integration into sample processing equipment, too.
