Our Electroscope Rod Assembly is designed to be a replacement for our Flask-Type Electroscope (#4-50150), though it can be used to create an electroscope of your own. At one end of the rod assembly there is a clip for holding electroscope foil. The stopper has a bottom diameter of 28mm and a top diameter of 32mm. This size is intended to fit a standard 250ml Erlenmeyer flask. If you want to use a different sized stopper when creating your own electroscope, the rod has 6.2mm diameter and will fit in any stopper with a hole of that size.
