| No. 3305-46A with airlock and accordian sleeve/glove combination |
-
1.5" (38 mm)-thick reinforced acrylic walls support full vacuum (to 29.9"Hg)*
- Dual hose barb fittings simplify connection to vacuum pump to allow rapid air removal and backfill with clean, dry process gas
- Perfect for anaerobic processing in a low-humidity nitrogen or argon environment
- Select Trace Oxygen Analyzer to maintain single-digit oxygen concentration (requires optional Purge Gas Connection Kit No. 3305-50)
The Series 210 Glovebox supports a wide range of vacuum and degassing operations.
This vacuum capability also allows removal of atmospheric humidity and oxygen and backfill with a process gas, quickly providing a moisture-free, low-oxygen environment for applications as diverse as Lithium battery manufacturing and anaerobic pathogen studies.
For automated vacuum control, select the Vacuum Control Module, pump and connection kit below. For automated backfill and purging, select the Dual Purge System and Trace Oxygen Analyzer, which work in tandem to provide oxygen levels down to 1 ppm(v). The Purge Gas Connector Kit is required for use with the Dual Purge System and/or Trace Oxygen Analyzer (order separately below).
The optional air lock allows transfer of materials into the glovebox without breaching the controlled environment.

* Vacuum Warning
The Series 210 Glovebox is designed for intermittent vacuum service as low as 29.9"Hg, as would typically be required in order to evacuate the chamber and backfill with process gas. Damage to welds can result if the chamber is exposed to continuous vacuum levels below 29" Hg. |

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.
