Our curved bottom and drainage holes make air-drying much more effective, which extends the life of your jar.THE LID THAT DOESN'T GET IN THE WAYThe vented gripper lid automatically vents steam when you're blending soups or other hot liquids. Plus, the lid's insert allows you to add ingredients on the fly. It's the ultimate convenience!NO DETAIL TOO SMALLEven the smallest parts in a Blendtec product have received big attention from our engineers.Blade assembly nutRound and smooth for easy cleaning—and—permanently attached at the factory – adding to jar safety.Bearing assemblySonically welded into the jar for extra strength and durability.THE FIGHT AGAINST FRICTIONFriction is the nemesis of all high-powered equipment. Ball bearings reduce friction so you can blend faster and quieter. It's all surrounded by a rubber mount that absorbs the shock produced by blending ice and frozen fruit.DARE TO BE SQUAREYou want your ingredients to blend, not just spin around in circles. Blendtec's square jar forces your ingredients from the blade and up the jar side, and then sucks them straight back down to the blade again.CERTIFIED SAFEBlendtec jars are made from Eastman Tritan copolyester.

They're also super easy to clean!The flat sides make it simple to scrape out remaining ingredients, and the broad single-blade design allows you to get underneath the blade for any remaining particles. No disassembly required!
