Flask Form Electroscope

Product Code : EL-PLE-13158Eduscope India is a leading Flask Form Electroscope Quick Answer: Flask Form Electroscopeis a simple, classic instrument that uses a pair of suspended aluminum leaves inside a 250ml flask to visually detect the presence and relative amount of electric charge.

When a charge is applied to the instrument, it distributes down to the pair of suspended leaves, which then repel each other and visibly separate because they carry the same sign of charge; the degree of separation gives a rough visual indication of how much charge is present. It is supplied by EduScope India as part of the company's physics demonstration kit India range underPhysics Lab Equipment. The instrument is housed in a 250ml borosilicate flask, with a metal rod attached to a rubber stopper that seals the flask's neck; inside the flask, a pair of aluminum leaves is suspended from an alligator clip fitted to the lower end of the rod, and a knob on top of the rubber stopper is where the charge is applied. When a charge is applied to the knob, it travels down the rod to the alligator clip inside the flask, and the aluminum leaves separate, giving a clear visual indication of the presence of charge. Also available separately from EduScope India are a rod and alligator clip assembly, for laboratories that want to fit the assembly to their own flask, and replacement aluminum leaves, useful for labs that want to reuse existing glassware or replace leaves that have become worn or damaged over time.

It is part of EduScope India'sPhysics Lab Equipmentrange. EduScope India'sGold Leaf Electroscopeis a closely related charge-detection instrument, working on the same leaf-divergence principle but using gold leaves in place of aluminum. For a ready source of charge to demonstrate with this electroscope, theVan de Graaff Generator, Small Electricis a natural pairing, letting students bring a controlled static charge to the knob and watch the leaves respond.
