The 6800-18 Aquatic Chamber is used to measure steady-state carbon assimilation and chlorophyll a fluorescence from an algal suspension using the LI-6800 Portable Photosynthesis System, the preferred photosynthesis system for terrestrial plant research.
In contrast with typical oxygen-based measurements of algal photosynthesis, where photosynthesis is derived from the change in O2 concentration over time, the LI-6800 is an open, flow-through, steady-state gas exchange system where CO2 and O2 concentrations are constant during the measurement.
From basic irradiance response measurements to complex multifactor experiments, the aquatic chamber can be used to evaluate biological responses to different environmental conditions.
