Closed Case Form Electroscope; from Sargent Welch Item #WL1963A; includes original box and instructions and two extra leaves; A Sturdy Workhorse for Student Labs This economical electroscope is enclosed, preventing air currents from affecting the deflection of the leaves. Leaves are developed to provide strength without sacrificing sensitivity. Each leaf is suspended from two small hooks, making installation simple. The leaves pivot, rather than bend, when charged. The metal case eliminates deflections caused by charges residing on glass walls. Leaf support rod is held in place by an insulating plastic sleeve. Front and rear sides of box are made of a 10cm square glass to allow visibility and shadow projection.
