Warburg manometer supplied by Hospital & Laboratory Supplies Ltd., and used by McIlwain in metabolic studies on brain tissues, 1968. McIlwain was the first to examine the metabolism of brain tissue when it was electrically stimulated. The manometer detected the amount of oxygen used by the sample, which increased as the chemical activity increased. Warburg designed this type of manometer in the 1920s. It was clipped to the edge of a thermostatted bath so that the reaction vessels (1981-371) dipped in the bath and could be maintained at body temperature.

Four glass electrode vessels used with Warburg Manometer (1981-369) in metabolic studies on brain tissue by Henry McIlwain, early 1950s. McIlwain was the first to examine the metabolism of brain tissue when it was electrically stimulated. He designed these special reaction vessels; the electrodes inside them were used to pass electric current through pieces of brain tissue. The attached manometer was clipped to the edge of a thermostatted bath so that these reaction vessels dipped in the bath and could be maintained at body temperature.
