Blendtec 40-619-62 Blender Jar, 2 Quart, Red Blendtec products are built to the highest commercial standards. No tamper/plunger needed. Commercial-grade jar is compatible with all Blendtec blender models (not compatible with Blendtec mix n' blend models). Reduce risk of allergen exposure by using separate color-coded containers. Versatility and customization for specific use. Our Patented, five-sided jar with extra-wide base and narrow fifth "wild" side automatically pulls ingredients toward the blade, instead of just spinning them around in a circular jar. It increases blending efficiency for frozen ingredients by up to 25% and provides an over all faster, smoother blend. The Wild Side+ jar also features two vertical ridges on the interior walls to disrupt the blending pattern even further. Includes blunt safety blade which is 80% thicker and ten times stronger than other blades. Made from durable Eastman Tritan copolyester; lightweight material for easy lifting and pouring. 3 corners for simple pouring at multiple angles. The Wild Side+ jar is a 64 oz volume jar with 32 oz blending capacity and easy-to-read jar markings. Blendtec jars are BPA-free, NSF certified, and impact resistant. 3 year comprehensive warranty. An American company, family-owned and driven to build the best quality products - without compromise. Engineered and assembled in the USA.
