This Electrode Rod Set is self contained and can be rested directly over the edge of a small beaker.
They are complete with an MES threaded lamp socket that accepts a standard small torch globe to show that current is passing between electrodes. The rating of the globe may vary depending on the conductivity of the electrolyte and the experiment being conducted.
This set has two stainless steel rods fixed at a separation of 1.5mm so they can fit inside a 10mm diameter test tube. A globe may be screwed into the socket provided to monitor the current flow. Two 4mm spin-free socket head terminals are provided for connection.
