The Sunderman Conductivity Bridge, often used in conjunction with a conductivity cell and a water bath, measures the electromagnetic conductivity of small quantities of biological fluids. It is specifically designed to determine a sample serum's total base and to estimate its serum sodium, which has important clinical implications. Tests can be made using only 0.5 ml of sample.
