The Vitamix 32-Ounce Container is made from BPA-free Eastman Tritan copolyester and designed to be lightweight and compact, and to keep liquids from leaking into the motor base. The spill-proof spout and vented lid make it safe and convenient to blend and pour both hot and cold mixtures. The blade base is compatible with Vitamix C Series and G Series blenders and features laser cut blades made from hardened stainless steel for strength and durability.
