A burette clamp is a laboratory apparatus that is used to hold and secure a burette, a graduated glass tube with a stopcock valve at one end, which is used for precise measurement of liquids. The clamp is typically made of metal, such as stainless steel or aluminum, and consists of two opposing jaws that can be adjusted to fit the size of the burette being used.
The jaws of the burette clamp have rubber or plastic-coated surfaces to prevent the burette from slipping or breaking during use. The clamp can be attached to a laboratory stand or support rod, which allows the burette to be positioned at the desired height and angle for easy measurement and dispensing of liquids.
Burette clamps are commonly used in analytical chemistry, biochemistry, and other laboratory settings where precise measurement of liquids is required. They are also used in educational settings, such as high school and college chemistry labs, to teach students about laboratory equipment and techniques.
