Oxygen electrode systems are available for the measurement of oxygen evolution or uptake from chloroplasts and other suspended plant photosynthetic materials (micro-algae etc.) and oxygen consumption by various components including plant roots or various plant or animal cell suspensions including mitochondria respiration studies. These may be effectively monitored using different combinations of modular items that together form compact, user-friendly systems for research applications or teaching.

Gas-phase oxygen electrode systems allow the measurement of oxygen evolution or uptake within a sealed sample chamber. The sample chamber is designed to accommodate 10cm² leaf discs which are cut using a special leaf disc cutter. However, any sample type such as root sections, lichens, mosses, conifer needles or small seeds may be used.
