The glove box uses the control system combined with the recycling column to circulate and purify the gas atmosphere in the box. The content of water and oxygen is controlled below 0.01ppm. Different gas supply such as argon and nitrogen are selected to provide excellent protection for the chemical reaction sensitive to water oxygen and drug storage.
