Designed for cutting-edge research, yet easy to learn, the LI-6800 is both a remarkable teaching tool and a powerful research instrument that provides the ability to answer new questions.
By controlling environmental conditions in the chamber for the duration of a measurement, the LI-6800 prevents multiple parameters from confounding the plant responses, ensuring more repeatability and confidence in the results.
By controlling chamber conditions, the photosynthetic response to changes in intercellular CO2 concentration is not confounded by other independent variables. The LI-6800 controls the leaf chamber environment at the setpoints with low variance (n = 3; ± standard error of the means).
Leaves are illuminated with constant irradiance, ensuring consistent light-dependent biochemical reaction rates.
The chamber light sources illuminate the leaf with uniform light. Variation typically is less than ± 10% over 90% of the aperture, ensuring that photosynthesis is even across the entire chamber aperture. The average photosynthetic carbon assimilation reflects the true spot-to-spot rate across the enclosed leaf area when the leaf is uniformly illuminated (n = 3; ± standard error from the means).
The flow rate is maintained precisely at the setpoint, which prevents flow from confounding the calculated carbon assimilation rate.
The LI-6800 Portable Photosynthesis System and accessories provide unprecedented capabilities to advance research in many different applications.
