A glove box is a sealed container that is designed to allow one to manipulate objects where a separate atmosphere is desired. Built into the sides of the glove box are gloves arranged in such a way that the user can place their hands into the gloves and perform tasks inside the box without breaking containment. Part or the entire box is usually transparent to allow the user to see what is being manipulated. Two types of glove boxes exist. The gas in a glove box is pumped through a series of treatment devices which remove solvents, water and oxygen from the gas. Heated copper metal (or some other finely divided metal) is commonly used to remove oxygen; this oxygen removing column is normally regenerated by passing a hydrogen or nitrogen mixture through it while it is heated: the water formed is passed out of the box with the excess hydrogen and nitrogen.
- This phrasing is common for lower-end, bench-top glove box models with a purge-style release that do not typically include a gas management system. Rather, inert gas is constantly pumped into and purged from the enclosure to maintain low O2 and H2O levels. These are more common among less sensitive applications.
- Older glove boxes often benefit from modern controls and a superior gas purification system that simply wasn’t available during initial production. At Inert, we welcome these opportunities to elevate our customers’ working potential. Our gas management systems, sensors, and other glove box parts can be outfitted to older glove box models, whether manufactured by us or not.
- Similar to an application glove box systems, this is a standard glove box that has been customized to fit a specific need, such as to integrate with original equipment manufacturer (OEM) tools.
- Gloves are the human interface to the enclosure. The gloves allow someone to work inside the glove box from the other side of the glass, keeping both the process and person safe. Gloves are made in different sizes, and configured for ambidextrousness or a left/right-hand fit. To ensure process integrity and safety, different glove materials are used in design.
- High-performance butyl gloves, like those standard on Inert glove boxes, are anti-static and resistant to chemicals, ultra-violet light, and ozone, as well as impervious to gas and liquids of most any kind. Butyl gloves are most common in microelectronics, wet chemistry, pharmaceutical production and medical device manufacturing. CSM (aka Hypalon) gloves are commonly used in the presence of high heat or oxidizing chemicals, used in some pharmaceutical and medical industries.
- HEPA filters are used in glove boxes and much larger enclosures, like clean rooms, and need to be replaced periodically to ensure that they are working at maximum efficiency.
HMI panels are also designed to quickly alarm the operator, should anything ever go wrong. Inert uses color touch screen HMI panels with a programmable logic controller (PLC) by Siemens to provide easy glove box interaction.
