All previous tests were done in the open air, but now it is time to actually start using the nitrogen purifier that I made. The system was originally designed to be used enclosed but I quite quickly found some design flaws that prevented the system from getting a low enough oxygen level. This required some parts to be redesigned and remade. In the end the prototype is now able to achieve an oxygen level that is the same as the input gas, meaning that the 5 liter/min that is being flushed into the system is enough to keep any oxygen out.
