Beakers are common lab glassware use to mix, stir, or heat liquids. They’re typically cylindrical in shape with a small spout at the top to facilitate pouring.
Though markings on the side indicate volume, there are much better glassware pieces to measure liquids; graduated cylinders and volumetric flasks are specifically designed for accurate measurement of volume.
This beaker is made with a borosilicate glass with the tradename of Pyrex (as evidenced by the “PYREX” on the side”). Glasses like these have a very low thermal expansivity making them ideal for applying heat sources. Other glasses that expand with temperature run the risk of cracking or breaking when the heat source is too localized or when heating or cooling occurs too rapidly.
