Many manufacturing processes and laboratory procedures must be carried out in a modified atmosphere as the process or procedure is sensitive to ambient air, vapors or dust. Often a process involves hazardous materials where a barrier to protect the operator is needed.
A glove box provides a means of performing the operations while maintaining the environment. Oxygen content is often monitored in glove boxes for oxygen sensitive products or to measure leaks or control the quality of the blanketing gas used to purge the glove box.
