[Semiautomatic potentiometric titration of gastric juice]

Using commercial equipment manufactured in this country, the authors have assembled a unit for semiautomatic potentiometric titration and developed a method for such titration, permitting a rapid determination of free and bound HCl and the total acidity of the gastric juice. The equipment and method are recommended for wide use at laboratories of therapeutic institutions, of biologic factories manufacturing medicinal commercial gastric juice, and of research institutes.
