AWT’s popular Tornadoâ„¢ Ink Mixer & Color Blender is ideal for mixing matched colors, adding pigments to bases, or blending reducers and other modifiers. The unique design of the Tornado saves time by mixing right in the original ink container. Mix quantities as small as a liter or quart, or as large as 25 liters or five gallons with one unit, using different-style blades.
