You appear to be referring to two types of laboratory flasks: the Florence Flask and the Boiling Flask. These are common glasses used in chemistry and biology labs for a variety of applications.
A “Florence Flask” is a form of scientific glassware, specifically a round-bottomed flask. Florence flasks are usually formed of borosilicate glass, which is resistant to heat and chemical reactions. The bottom of a Florence flask is rounded, and the neck is long and narrow. The circular shape promotes even heating and boiling of liquids. The flask’s large neck is important for limiting vapor escape, making it suited for procedures such as distillation. Florence flasks are extensively used in laboratories for a variety of applications, including distillation, liquid heating, and gas collecting reactions. The flask’s form is ideal for applications requiring regulated heating and evaporation. Florence flasks range in size from tiny to big, depending on the volume of substances handled in a given experiment or operation.
A boiling flask is a form of scientific glassware used for heating and boiling liquids. It is also known as a round-bottom flask or Florence flask. It has a long neck and a circular bottom. The circular shape provides for equal heating of liquids, while the long neck reduces volatile substance loss. Boiling flasks are often employed in laboratory applications such as distillation, reflux, and other chemical reactions involving liquid heating. The flat-bottomed flask, on the other hand, is known as an Erlenmeyer flask or a boiling flask. The bottom of these flasks is flat, triangular, or trapezoidal in shape, providing sturdiness on a flat surface. Boiling flasks, regardless of shape, are crucial laboratory instruments for a wide range of chemical and biological studies requiring controlled heating and boiling of liquids.
