A round-bottom flask is a laboratory glassware that has a spherical bottom and a long neck with an opening that can be sealed with a stopper or a joint. The flask is typically used for heating and boiling liquids, as its shape allows for even distribution of heat and prevents the formation of hot spots.

The ROUND-BOTTOM-FLASK-500ML, as the name suggests, is a round-bottom flask with a capacity of 500 milliliters. It is made of high-quality borosilicate glass, which makes it resistant to heat, thermal shock, and chemical corrosion. The flask has a standard ground joint and is compatible with other laboratory glassware, such as condensers and heating mantles.

The ROUND-BOTTOM-FLASK-500ML is commonly used in chemistry and biochemistry research for a variety of applications, including distillation, reflux, and synthesis reactions. It is also used in the production of pharmaceuticals and fine chemicals. When using this flask, it is important to handle it with care to avoid breakage, and to use appropriate heating and cooling methods to avoid thermal shock.
