The Burette Clamp With Boss Head, Coated Jaws by United Scientific is a single-position clamp with a built-in boss head for holding burettes, tubes, and other small objects from 15 mm to 45 mm in diameter. PVC sleeves on the jaws give a firmer grip on glass, and the jaws rotate and lock at any angle. It attaches to support rods up to 13 mm (0.5") O.D. and is used in titration and general bench setups.
