Typically made of borosilicate glass, laboratory glass beakers are used to hold liquids, heat them, and mix them. They are available in various sizes, shapes, and materials, and can be used in a number of different applications. The most common application is for heating and stirring liquids. In addition, they are often used for mixing chemicals. They are also used to measure liquids, storing liquids, and transporting liquids.
Glass beakers are cylindrical containers with a flat bottom, a small pouring spout, and reinforced rims. They are typically manufactured with boron trioxide, which allows them to resist rapid changes in temperature. Some beakers are marked with lines to indicate the volume. They are available in various sizes, ranging from one milliliter to several liters.
Laboratory glass beakers are available in both short and tall forms. The taller beakers are designed to be twice as tall as they are wide. The lower form beakers are designed to be one and a half times as tall as they are wide. They may have handles for pouring.
Laboratory glass beakers are available with either a glass handle or a metal handle. A stainless steel beaker is very durable and can withstand temperatures of 550 deg C. Aluminum beakers are lightweight and can withstand temperatures of 340 deg C. Polypropylene beakers are often used for gamma spectroscopy. They are manufactured using an automated process and are shatterproof.
