With the introduction of the S50, Vitamix redefines personal blending, again. In addition to the features found on the S30, like Variable Speed Control, Pulse, easy countertop storage and two container sizes, the S50 offers two pre-programmed settings to take the guesswork out of blending. These programs are specially formatted to deliver optimal processing times for Smoothies and Power Blends. Designed to automatically shut off when the selected cycle has completed, the S50 makes it easier than ever to achieve your perfect blend.
