| titleOfInvention | Nitrogen fixation enzyme activity measuring device improved by acetylene reduction method |
| abstract | The utility model discloses a nitrogenase activity measuring device improved by an acetylene reduction method, which comprises a sealed reaction bottle, wherein the mouth of the sealed reaction bottle is provided with an isobutyl rubber plug, a gas sample inlet pipe and a nutrient solution sample inlet pipe are fixed on the isobutyl rubber plug, the gas sample inlet pipe is sequentially connected with a first valve and a second valve, and the other end of the gas sample inlet pipe is communicated with an injector through a rubber plug; the nutrient solution sampling pipe is sequentially provided with a third valve and a multi-connection pipe valve; the multi-connection pipe valve is connected with a nutrient solution bottle; the sealed reaction bottle is positioned in the porous heat-preservation type vibration plastic component. The utility model solves the problem of air leakage caused by pinholes in the process of measuring the activity of azotase, reduces the system error of each reaction system and improves the reproducibility of experimental results; meanwhile, due to the design of the multi-joint valve, an operator can finish more sample pretreatment in batches within a certain time, and the experimental efficiency is improved. |
