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 Laboratory
Glove Boxes. 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.
FUNCTIONS-
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, this is a Portable
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.
