Which device is used to hold burets on a stand in a lab setup?

• A. Burette Clamp, Coated Jaws
• B. Beaker
• C. Florence Flask
• D. Concave Microscope Slide

Answer: (A)

Holding a buret securely on a stand requires a device designed specifically for gripping glass and attaching to a support. A burette clamp with coated jaws fits this need perfectly: the clamp grips the buret firmly and can be attached to a stand, keeping the glass vertical and stable during titration. The coated jaws protect the delicate glass from nicks or slipping, which helps maintain accurate volume readings as the meniscus is observed. In contrast, a beaker is just a container for liquids, a Florence flask is a storage or mixing vessel, and a concave microscope slide is used for microscopy, none of which are intended to hold a buret on a stand.
