Q-Box NF1LP Nitrogen Fixation Package

Qubit Systems produces the only complete experimental package Q-Box NF1LP for measurement of Nitrogen Fixation in H2 Producing Legume Symbioses. The unique flow-through H2 sensor (Q-S121) measures the production rate of H2 from N2-fixing tissues, allowing in-vivo measurement of nitrogenase activity in real time. When combined with Qubit Gas Switching System measurements of Nitrogenase activity on upto 3 Plants is possible (4 Channel System including reference)

Measurement of H2 Evolution as a means of determining Nitrogenase activity overcomes all the problems of the traditional acetylene reduction assay. The Q-Box NF1LP Nitrogen Fixation Package is perfectly safe, non-invasive and allows changes in nitrogenase activity to be observed as they occur.

The Nitrogen Fixation Package contains everything required to conduct numerous laboratory investigations into the physiology and biochemistry of N2 fixation in an open-flow gas exchange system. We even supply legume seeds and innoculum! Calibration of analyzers is simple, set-up time is minimal and experiments are easy to perform. This system is not designed for field use.
