The salt bridge is used to connect the oxidation and reduction half-cells of a galvanic cell. It allows ions to flow from one solution to the other without mixing the solutions (thus completing the electrical circuit) and allows the solutions in the two half-cells to remain electrically neutral.
Eisco Labs Borosilicate glass has the following heat tolerances: Strain Point -515°C | Annealing Point 565°C | Softening Point 820°C.
