It's about the device.

In general, laboratory stirring devices are widely used for the purpose of mixing or stirring samples such as reagents, samples, and raw materials in laboratories such as schools, hospitals, and pharmaceutical companies. In such an experimental stirring device, test tubes, ampoules, flasks, beakers, etc. are used as various types of containers for accommodating the stirring object, and a rack for holding the container accommodating the stirring object in the stirring device is utilized.

In the case of these racks, they are configured and utilized in various shapes to fit various types of containers. In the case of racks installed in the conventional experimental stirring device, most of the racks are composed of a fastening method by a fastening mechanism, so replace them with a desired type of rack. In this case, it is complicated to separate the fasteners one by one and then replace them again, which is inconvenient to use.

Of course, in order to solve this inconvenience, each stirring device is purchased according to the shape of the rack and used for an exclusive purpose, but this is economically burdensome and wasteful.
