Principle of Vacuum Glove Box

• Vacuum Creation: The first step in operating a vacuum glove box is to create a vacuum inside the chamber. This is achieved using vacuum pumps. There are different types of vacuum pumps, such as rotary vane pumps, diaphragm pumps, and turbomolecular pumps. These pumps work by removing air and other gases from the chamber, reducing the pressure inside. The lower the pressure, the fewer gas molecules are present, minimizing the chances of contamination from oxygen, moisture, and other substances.[!--empirenews.page--]
• Inert Gas Purge: After creating a vacuum, an inert gas such as nitrogen, argon, or helium is introduced into the chamber. Inert gases are chemically unreactive under normal conditions. By filling the chamber with an inert gas, a stable and contamination - free atmosphere is created. Some glove boxes are equipped with gas purification systems that can further remove any remaining traces of oxygen, moisture, or other impurities from the inert gas.
• Sealing and Isolation: The glove box is designed with high - quality seals to prevent air leakage. The gloves attached to the ports are made of flexible materials that allow for easy manipulation while maintaining the integrity of the sealed environment. The ports are also sealed around the gloves to ensure that no air can enter or exit the chamber through these openings. Additionally, some glove boxes have airlocks, which are small chambers that can be used to transfer materials in and out of the main chamber without significantly disrupting the internal atmosphere.
• Monitoring and Control: Vacuum glove boxes are equipped with sensors to monitor the internal atmosphere. Oxygen sensors and moisture sensors are commonly used to measure the levels of these substances. The data from these sensors is used to control the gas flow and purification systems. For example, if the oxygen level exceeds a certain threshold, the gas purification system can be activated to remove the excess oxygen, maintaining the desired atmosphere inside the box.
