What is a carboy primarily used for in a laboratory?

A carboy is primarily used for storing large volumes of liquid, making it an essential piece of equipment in many laboratories. These containers are typically made from glass or plastic and can hold several liters of liquid, such as water, chemicals, or biological cultures. Their design allows for safe storage, ensuring that the contents are protected and can be accessed when needed.

In the laboratory setting, it's crucial to have appropriate storage solutions for bulk liquids. Carboys often come with sturdy handles and secure closures to facilitate transport and minimize the risk of spillage. Their size and material properties make them ideal for long-term storage compared to smaller containers, which might not be practical for significant quantities of liquid.

In contrast, options related to heating substances, measuring precise volumes, or mixing chemical reactions represent different functionalities typical of other laboratory equipment. Heating is generally done using equipment like Bunsen burners or hot plates, precise measurement of liquids is typically accomplished with graduated cylinders or pipettes, and mixing is carried out in flasks or beakers designed for that purpose.
