Borosilicate Glass U-Tube Salt Bridge

This Eisco Labs Borosilicate Glass Salt Bridge features an inverted U-shape with tightly closed ends. The bridge stands 6.5" tall and 4.375" wide between the arms. Outer diameter of the U-tubes is 0.53" (inner 0.41"), and the bottom tube is 0.32" outer (0.19" inner). Salt bridges connect the oxidation and reduction half-cells of a galvanic cell, completing the circuit by allowing ion flow. This glass salt bridge is suitable for electrochemistry experiments in chemistry classrooms and laboratories.
