Which clamp is used to hold burets and is coated with plastic or rubber?

• A. Burette Clamp, Coated Jaws
• B. Beaker
• C. Centrifuge
• D. Forceps

Answer: (A)

Holding a buret requires a clamp designed to grip delicate glass without scratching or slipping. A buret clamp with plastic or rubber-coated jaws is ideal because the coating cushions the glass, distributes pressure evenly, and provides a secure, non-slip grip. The coating also protects the metal jaws from corrosion and reduces potential damage to the buret during clamping, which is important for maintaining the accuracy of titration measurements. The other items don’t fit this purpose: a beaker is just a container, a centrifuge is used for spinning samples, and forceps are hand-held tweezers.
