Nitrogen is the one of the non-metal elements with chemical symbol N and atomic number 7. It is a colorless gas at normal pressure and temperature, it is the major component of the atmosphere, is considered an inert gas.
Nitrogen it frequently used in exciting experiments at the temperature of -210°C in liquid form to freeze everything, and to demonstrate some physical laws. You can see these on YouTube searching "liquid Nitrogen experiments".
We suggest this element at the purity of 99,999% in a 10 cm long ampoule and 2 cm of diameter.
We use the low pressure to light it easily with a 2kV transformer, which you can find on amazon. You can see this in our pictures.
Normally available in two weeks you can order alone or with other elements, we send first all the elements in stock and when it is ready we send for free in a second time.
