Today I take a little while to address cleaning glassware, especially when it’s coated with caked on organic and inorganic debris from past experiments. Griffin beakers are used to mix chemicals, dissolve into solutions, heat or cool solutions, and hold sand or water baths. Weigh the glassware with the water and record the value. The flask may also be called a graduated flask or measuring flask because its mark specifies a precise volume measurement.
