This glove boxmaintains several critical environmental control capabilities essential for medical device biocompatibility testing, tissue cultivation studies, and other biological research:
Humidification/Dehumidification Cycling: Under precise PLC set point control, the system purges the chamber with water vapor to humidify the process environment; or with dry nitrogen to drive the humidity level below 1% RH. An onboard RO filter system removes contaminants from the water vapor.
Oxygen Concentration Control: Maintains precise O2 set point concentration down to 0% to allow anaerobic processing.
Heating/Refrigeration Modules: rapid cycling between 40° and 140°F.
VHP® Biodecontamination System: vaporized hydrogen peroxide sterilizes the chamber between processing operations. A silica gel filtration module helps maintain a precise 30% H2O2 concentration.
HEPA Filtration: Process gas circulates through a 99.99% HEPA filtration module to remove airborne contaminations.
To eliminate embrittlements that result from a high-humidity welding environment, this chamber maintains a dry nitrogen environment with automated humidity controls.
The glove box features a pass-through vacuum/nitrogen oven for degassing at temperatures up to 300°C, and a right-side air lock for easy parts removal. A trace gas mixer provides a precise He/N2 gas mixture during seam welding, which allows for subsequent leak detection in a vacuum chamber. Ionization equipment provides fail-safe static neutralization to protect against ESD in the low-humidity environment.
Sealed quick-connect ports permit easy connection of welding electrodes, and dual service utility outlets are provided for 110/220VAC, 50/60Hz power.

Packages are cycled through a vacuum chamber to remove moisture prior to introduction into the main stainless steel isolation chamber. A dry nitrogen purge maintains a low humidity level for processing. A Nitrogen Generator provides a continuous flow of 99% pure nitrogen.
Parts are removed via the pass-through vacuum chamber, where they may undergo a second degassing cycle.
Designed to provide a clean, moisture-free environment for applying photoresist, this glove box is large enough to accommodate wafer spinners used in the deposition process.
It incorporates a high-volume process gas mixer that controls percentages of two process gases. A three-sided plenum design recirculates the process gas through dual filter/fan modules for HEPA filtration (99.99% efficient @ 0.3µm particles). Magnehelic® gauges and backpressure alarms ensure filter/fan efficiency. In addition, the bottom plenum includes cooling coils that compensate for heat-generating process equipment to ensure a constant temperature of 68°F.
Dual-side air locks afford easy loading and unloading of wafers. The radius corners of all internal seams allow easy wipe-down and eliminate cracks where particles can collect.

A continuous purge of filtered N2 maintains low humidity and particle counts inside these probe station enclosures. Self-balancing ionizing equipment neutralizes static charges to protect against electro-static discharge (ESD) in the low-humidity environment.
Accordion-sleeve gloves provide easy access to the probe station, including sensitive X-Y-Z controls. A microscope lens diaphragm seals around eyepieces to permit focusing without disturbing the internal environment. The removable, resealable back or side walls permit installation of bulky probe equipment.

What makes a glovebox an "isolator"? Or a "mini-environment"? What does "WG" mean? Our glovebox glossary explains . . .
Acrylic's Hidden Costs
Acrylic attracts and aggregates particles, adding to cleaning costs. It's difficult to sterilize. It poses a serious ESD (electro-static discharge) threat.
