Glass flask

A glass flask is a container made of glass that is typically used for holding and storing liquids. Glass flasks come in a variety of sizes and shapes, with some being flat-bottomed and others having a rounded or bulbous shape. They can also have a variety of features such as a narrow neck with a stopper, a wide mouth for easy pouring or filling, and graduations or markings for measuring the volume of the liquid inside.

Glass flasks are commonly used in scientific and laboratory settings for holding and mixing chemicals, as glass is a non-reactive material that can withstand a wide range of temperatures and is not easily affected by chemicals. They are also commonly used for storing and transporting liquids such as alcoholic beverages, oils, and other liquids.

Glass flasks can be made of various types of glass, including borosilicate glass, which is known for its high resistance to heat and chemical corrosion. Some glass flasks may also be coated with a layer of plastic or rubber to provide additional protection or to help prevent breakage.

Overall, glass flasks are a versatile and useful type of glassware that can be used in a variety of applications, both scientific and practical. They are durable, easy to clean, and can be reused many times, making them a cost-effective choice for many users.
