Electromagnetic impulses activate these Sieve Shakers and thanks to the triple vibrating action (vertical, lateral and rotational) they are recommended to perform sieving tests where high precision and performance are important, and where continual and intense uses are required. Therefore they are suggested for accurate sieving tests, on fine materials too. These Electromagnetic Shakers are of simple and sturdy construction, they can hold up to 10 sieves and are also suitable for wet sieving tests (accessory mod. A046, A047).
