Sift heavy minerals, light organic samples, and fine pharmaceutical powders with this electromagnetic shaker. It has no motor and no moving parts—making it virtually maintenance free. The shaker provides a unique vibratory motion by using a horizontal and vertical sieving action to effectively separate materials. Use the built-in 60-minute timer to easily repeat any test. Shaker holds up to 8 full-height or 16 half-height, 8'' diameter sieves with bottom pan and cover. Sieves are held securely in place with clamps.
