The Vitamix 64-Ounce Container is made from BPA-free Eastman Tritan copolyester and designed to handle large batches and 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. Use the included tamper to safely push ingredients into the container. The blade base is compatible with Vitamix C Series blenders and features laser cut blades made from hardened stainless steel for strength and durability.
