About This Product
The clamp's rod is mounted in a boss head or support holder, and the arm is set at the height and angle needed. It holds beakers, Erlenmeyer flasks, boiling flasks, test tubes and burettes for heating, titration, filtration or observation in chemistry, biology and physics practicals. The screw is tightened gently so the vinyl-coated fingers grip the glass without breaking it.
