The Ross double planetary mixer lined with Teflon is ideal for high-purity applications, providing superior chemical and corrosive resistance where stainless steel is not compatible. Highly versatile, the double planetary mixer can process viscous pastes and dough-like materials as easily as it can prepare dry powder blends and wet granulations. It provides gentle but thorough agitation required by shear-sensitive gels and fragile fiber-filled mixtures. This mixer is also frequently used for vacuum drying operations.
