  • Designed for rapid removal of oxygen and backfill with nitrogen or argon to establish anaerobic processing environment
  • Continuous-seam welds with radius corners simplify cleaning and reduce leak rate during vacuum cycling (supports intermittent negative pressure as deep as -5" Hg with glove port covers on)
  • Optional vacuum controls accelerate oxygen removal and backfill with inert process gas
  • Select Trace Oxygen Analyzer and Dual Purge System to maintain oxygen levels to 1 ppm

Nitrogen generator Nitrogen Generators give you a reliable point-of-use supply of up to 99%-pure nitrogen. Eliminate the drawbacks of canisters and 3rd-party suppliers! You control volume, purity and rate; all you need is a clean compressed-air feed. Terra's three sizes of maintenance-free membrane generators meet several capacity requirements are ideal for back-filling or continuous flow into desiccators, glove boxes, vacuum chambers and incubators. 

The Series 310 Stainless Steel Glovebox features reinforced 12-gauge stainless steel construction with continuous-seal welds to support vacuum pressure/inert gas backfill cycling that quickly removes atmospheric oxygen and moisture. A tempered safety glass window and fluorescent light provides visibility of the work area.

For automated vacuum control, select the Vacuum Control Module, pump and connection kit below (Recommended pump and accessories.) For automated backfill and purging, select the Purge Control Connection Kit, Dual Purge System and Trace Oxygen Analyzer, which work in tandem to provide oxygen levels down to 1 ppm(v). Right or left-side air locks allow transfer of materials into the glovebox without breaching the controlled environment.

How to Attain Extremely Low RH/O2 Concentrations:
Vacuum Cycling vs. Purge and Bleed

Vacuum cycling provides the quickest, most economical way to achieve extremely low moisture and oxygen levels inside a glovebox.

Purge-and-bleed displacement relies on a continuous purge of dry process gas (typically, nitrogen or argon) to displace moisture-laded air, which exits through a bleed valve. This process typically requires many hours, consumes a high volume of process gas, and may never achieve very low oxygen concentrations (below 5 ppm) required in many applications.

Vacuum cycling evacuates ambient air – and with it, moisture and oxygen – inside a vacuum chamber or glovebox. When air is removed, you simply backfill the chamber with process gas until the chamber attains neutral pressure. If needed, this process is repeated until oxygen or moisture concentration reaches the desired level. Typically, only a few cycles, requiring only a fraction of the gas and time of a purge-and-bleed protocol, are all that’s needed to reach single-digit oxygen concentrations.

Once set point levels are attained, close off vacuum valves and use a Dual Purge System and appropriate controller (NitroWatch™ for relative humidity, Trace Oxygen Analyzer for O2 concentration) to maintain dry, anaerobic conditions.

Purge Connection Kit
Includes connection ports for: Automatic RB Valve, Trace Oxygen Analyzer sample lines (in and out), Dual Purge System gas in and system pressure lines. Each includes brass connection for 0.25" (6 mm)-diameter polyethylene line, and valving system that allows isolation when chamber is operating in vacuum mode. Price includes installation on top of main Series 210 Glovebox chamber. Order Dual Purge System, Trace Oxygen Analyzer, and Automatic RB Valve separately.
