About This Product
One opening of the boss head slides onto the vertical rod of a stand and is tightened, and a horizontal rod, clamp stem or ring goes into the second opening. This lets burettes, condensers, thermometers, funnels and small apparatus be held at the required height in chemistry and physics experiments. Before use, check for cracks, loose screws and worn threads, and tighten only enough to hold without damaging the rod.
