I am an M.pharm student working on project regarding keratin alginate nanogels where i have to maintain nitrogen atmosphere during the formulation process. Can anybody tell me how do i obtain and maintain nirogen atmosphere?
If an anaerobic glove box is available, that might be a good solution. If not, how about getting a nitrogen gas cylinder of the desired purity and flushing the chamber you will use initially and then continuously if needed? Good luck!
If you do not have a glove box, there are large sealable plastic bags available which you can purge with nitrogen gas into. A detector can be used to monitor the oxygen content inside the bag.
There are several options. You could use a nitrogen gas cylinder or cryonic liquid nitrogen to create the nitrogen atmosphere. A glove-box is preferable of course. To maintain said atmosphere, you can use a suitable container and a regulator to control the flow of gas.
Remember to take safety precautions as well, nitrogen gas displaced breathable oxygen.
