title: [Determination of the pH of solid tumors].
abstract: The design and production technique of pH-electrode for measuring pH in solid tissues are described. Main characteristics of the pH electrode are determined: external diameter 0.25-0.4 mm, length of the pH-sensitive part--4-10 mm, sensitivity at 37 degrees C--55-60 mV/pH, and drift--less than or equal to 0.005 pH/h.
