The Lincoln-Type Burette Clamp by United Scientific is a zinc-plated stamped steel clamp that holds two burettes on one support rod. It tightens with a steel thumbscrew, fits rods up to 19 mm (0.75") in diameter, and sets the burettes 18.4 cm (7.25") apart. Chemistry teaching labs and analytical benches use it to run paired titrations from a single stand.
