• A new simple volumetric apparatus for measuring the respiration, fermentation and photosynthesis rates in microorganisms was constructed. The apparatus, its operation and some data obtained with it are presented. This apparatus 1) has an open-capillary constant-pressure volumeter without a compensation chamber, 2) has a magnetic stirrer for stirring the reaction mixture, 3) can be used to measure with a sensitivity of 0.85 μl volume change per one mm reading without a microscope, 4) simultaneously uses seven volumeters, one of which is set as a thermobarometer, 5) is completely immersed in a water bath to minimize the effect of ambient temperature, and 6) simplifies calculation.
