The Nexus is a modular inert atmosphere laboratory and gas purification system with integrated instrumentation and control. The modular concept allows Vacuum Atmospheres to offer a wide variety of standard glove box sizes and configurations while maintaining common subassemblies and user interface. The instrumentation system allows the user to monitor and control all laboratory functions from a single location.
The operator or user interface consists of a four-button keypad and a color monitor with graphical displays for all system information. The displays include pressure, moisture level, oxygen level, purifier status, and blower speed. The operator follows an easy to use menu-driven operator interface for entering all information and initiating all available programmed operations. The operator interface allows inexperienced users to quickly operate even the most extensively optioned instrumentation system with only a few basic menu operations. The purifier system removes oxygen and trace moisture contamination in the hermetically sealed lab environment. These models of the Nexus System are equipped with single gas purifiers and manual circulation valves. The glove box is a hermetically sealed, stainless steel enclosure with a full-view window and 2 glove ports. A right-side attached 15” diameter antechamber is standard. The optional oxygen analyzer uses an electrolytic fuel cell to measure lab oxygen down to one part per million. The optional trace moisture analyzer uses an aluminum oxide probe to measure moisture levels down to less than 1 part per million. The Nexus System controls all moisture and oxygen analyzer functions through the operator interface.
