Review on 🔀 Efficient Magnetic Stirrer Spinbar Octagon Stirring: Enhance Mixing and Stirring Processes by Kevin Carr

When the solution is heated in a beaker on the stove, one of the two large wands begins to wobble rather than rotate as the speed increases. Take out the stirrer and replace it with another one of exactly the same size from this kit and immediately put it back up to the same speed and it spins properly and I can keep increasing the speed as the solution gets hotter. If I try to leave another stick in it, it will keep tumbling instead of spinning at a certain speed no matter how hot (more viscous) the solution gets. This is acceptable as I rarely mix more than one solution at a time even if I have a plate/mixer, but the quality control on the two large sticks wasn't the best.
