This product is mainly for those with relatively large chemical reactions, less solutions, faster solution mixing speed, and can only be mixed in test tubes, colorimetric tubes, and small and medium-sized Erlenmeyer flasks, providing ideal equipment. This instrument not only solves the problems that the stirrer cannot solve, but also saves a lot of labor, and at the same time makes the operation easier to master. And it’s fast and accurate. The principle of this machine is that the motor drives a certain angle of eccentricity.
