The Hielscher Ultrasonics has developed ring sonotrodes, run by the ultrasonic processor UIS250L . Hereby, a complete stack of common laboratory ring sieves (according to DIN ISO 3310/1 or to ASTM E 11-95) with diameters of 100mm to 400mm can be simultaneously incited by ultrasonic oscillations. In contrast to the ultrasonic sieving processes known up to now, in which each sieve needs its own ultrasonic incitement, this is a very inexpensive and flexible solution, which can be easily integrated into already existing sieving towers. Hielscher Ultrasonics also offers you complete sieving towers for laboratory use. previous page | next page |
