A common rubbing flask is a glass container used for chemical experiments. A flask with a small container mouth is a convenient item for stirring the solution. A common rubbing flask is a type with a standardized rubbing part of the neck so that it can be easily combined with other parts. It is possible to use multiple items with the same standard dimensions. It is used in various work sites such as chemical research and development. The shape of the common rubbing flask is various, such as the Erlenmeyer flask which is difficult to evaporate and the eggplant flask which is easy to scrape solid or candy-like liquid. There is also a common four-neck flask type that is convenient for inserting thermometers and chemicals, and you can select items according to your application.
