About This Product
This clamp is chosen when glassware has to be held off the vertical, such as a condenser angled for distillation, or when a burette must sit exactly upright for titration. Setting the jaws with two screws gives balanced pressure around the glass, and the built-in bosshead means the clamp goes on the stand rod without an extra connector.
Frequently Asked Questions
What do the two keys on the Burette Clamp, Rotatable, Double Keys 1 do?
