Vertical planetary ball mill is a necessary device of high-tech materials mixing, fine grinding, sample making, new product development and small batch production. Tencan planetary ball mill owns small volume, high efficiency, low noise and functional features which is a ideal equipment for R&D centers, universities, enterprises laboratory to get samples (each experiment can get four samples at the same time). It can be put into the glove box and grind any materials which have to be operated under the vacuum state or inert gas atmosphere inside the glove box.
