Demonstration Spherometer Subcategory_Weights and Masses gripping objects up to 90

gripping objects up to 90 mm and mounting to support rods up to 15 mm for chemistry and physics setups

fastened by two wide-pad stainless steel thumb screws under heavy torsional load

supplying replacements when the originals lose loft or split during repeated charging cycles

the moderate curvature spreading light gently for divergence and virtual-image-formation work in refraction demos

supplying an inert electrode that conducts current without contributing its own ions to the cell reaction
