Nitrogen Fixation System Model Q-Box NF1LP :

• Qubit Systems produces the only complete experimental package for measurement of nitrogen fixation in H2 producing legume symbioses – Q-Box NF1LP Nitrogen Fixation Package. 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. The Package contains everything required for successful experiments, including gas exchange pots for growing legume plants such as soybeans under nodule-producing conditions, all the nutrient recipes, and instructions. When combined with Qubit Gas Switching System measurements of nitrogenase activity on up to 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 measured as they occur in growing plants.
• 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. Calibration of analyzers is simple, set-up time is minimal and experiments are easy to perform.
