The ultrasonic sieve cleaner was designed for safe cleaning of testing sieves, it eliminates costly, damaging brushings. This results in longer life and maintained accuracy of sieves. Unsurpassed results are obtained on the fine mesh sieves. However, the true test of the ultrasonic sieve is its ability to clean above-fine meshes (20-1OO). The usual practice is to initially clean the plugged sieves with a severe 15-minute soak; and from then on, most sieves respond to less than 5 minutes of cleaning. Lightweight. Portable. Stainless steel tank with drain. With 30-minute dial timer (110 V only). Holds two 8″ diameter full-height sieves. Ultrasonic sieve cleaner, complete with generator and tank.
