Get more consistent blends with Blendtec’s Fourside Jar. This Blendtec replacement blender jar is ideal for blending ice cream, grinding grains and heating soups and drinks with friction. The square shape blends better in less time than traditional round jars, creating a vortex that minimizes cavitation and pulls ingredients towards the blade. It comes with a dishwasher-safe, non-vented soft lid that provides an airtight seal great for frozen drinks. The blender jar’s flat sides make it easy to scrap remaining ingredients, and the blunt safety blade is 80% thicker and ten times stronger than other blender blades on the market. This blender jar design increases blending efficiency for frozen ingredients by up to 25%. This commercial-grade blender jar is made from durable, lightweight material, and has three corners and an ergonomic handle for easy lifting and pouring.
