IKA Solids/Liquids Mixing

IKA's double-stage batch mixing system CMX offers an alternative to continuous solid-liquid mixing. Low pressure created in the mixing chamber leads to a dust-free suctioning of powders or other solids. The highly flexible machine is predestinated for solids, which are very difficult to wet as well as the insert of very big powder amounts.
