“Alterna 80 oz Jars and Blades” containers fit the JTC OMNIBlend blenders. The Alterna jar is reported as blending better, and is easier to clean, as well being made as a BPA-FREE copoloyester blender container. Spare blades are available too.

Note, for longer lasting blade bearings, keep out of dishwasher and hand-wash only, hand-dry. Make sure the bottom plate retaining nut stays hand-tight at all times to prevent damage to the jar. The Alterna jar sits on the JTC at a 45 degrees perpendicular.
