 The 4" growth system operates utilizing extreme conditions: the furnace reaches extremely high temperatures (>900 °C), the turbo pumps reach extremely low pressures (~μTorr), the growth feedstock gases are stored at high pressures (>1000 PSI), and many of these gases are flammable. The wrong combination of parameters can lead to costly damages or even lethal outcomes. Please be sure that you understand the dangers and risks before attempting to use the growth system. The 4" growth system operates utilizing extreme conditions: the furnace reaches extremely high temperatures (>900 °C), the turbo pumps reach extremely low pressures (~μTorr), the growth feedstock gases are stored at high pressures (>1000 PSI), and many of these gases are flammable.

 Under the right conditions, [[http://​en.wikipedia.org/​wiki/​Combustion|combustion]] (an explosion) may occur inside the quartz tube during standard furnace operation. This would involve a significant amount of oxygen being present during operation, which would likely be due to a leak of atmosphere into the chamber. The [[http://​www.science.oregonstate.edu/​~minote/​wiki/​doku.php?​id=nanotube_growth#​using_the_rga|RGA]] should be used to verify that oxygen levels during operation are in the safe zone. Under the right conditions, [[http://​en.wikipedia.org/​wiki/​Combustion|combustion]] (an explosion) may occur inside the quartz tube during standard furnace operation.
