Oh no. The one I have is diy style. 120mm fan with a 1/2 inch pvc stand off, two hard drive magnets are glued to the pvc stand off. The stand off is glued to the center of the fan. I use a magnetic stir stick that I got from university. The base is nothing more then acrylic that has two 90 bends in it, done with a heat gun and the edge of my work bench. The fan is suspended by 4 machine screws. 2l conical flask, hard to find, but well worth it for the flat bottom. I have no need of temperature control, I just use it to mix up fnb and maxi line of products. The stir plate eliminated a lot of mixing and shaking, it also insures that I got a consistent blend and that the powder completely dissolves. This is the diy guide I followed, eventually I would like to move up to a lab grade stir plate.
