Method and apparatus for measuring pressures of fluid materials used in medical procedures where purity and freedom from contamination are essential. An adapter having one or more highly resilient diaphragms therein is disposed serially within a passage leading to a pressure gauge from the material whose pressure is to be measured, thereby isolating the material which is on one side of the diaphragm(s) from the volume on the other side while at the same time transmitting the pressure from the material therethrough. By carefully selecting the characteristics of the diaphragm material, the desired sensitivity of pressure conduction is achieved while maintaining the integrity of the respective volumes on both sides of the diaphragm, achieving re-usability and preventing contamination.
