Summary
The construction of a thermostatted tonometry unit allowing the simultaneous equilibration of six blood or plasma samples with different gas mixtures is described. The tonometers rotate along their horizontal axis, insuring a large equilibration surface, resulting in equilibration with CO2 in the gasphase being reached within 10 min. Samples may be introduced into or withdrawn from the rotating tonometers at any time. The gas mixtures leaving the tonometer may also be analyzed at any moment.
