Upgrade your blending experience with the Bosch Vacuum Blender Attachment, compatible with Universal Plus, Universal, and MUM-3 mixers. This specialized attachment is engineered to create a vacuum seal before blending, a process that preserves vital nutrients, maintains vibrant colors, and enhances the texture of your smoothies and purees by significantly reducing oxidation. The set includes the clear blender jar with an integrated blade assembly, a secure gray lid, and the necessary vacuum pump (as shown). This system is ideal for health enthusiasts and anyone looking to keep their blends fresher, longer.
