Product Details
  • Heavy duty 1" thick acrylic walls allow for full vacuum 29.9 "Hg
  • Solvent-welded construction with continuous seams fuses walls together into one piece
  • Air lock minimizes particle influx during sample transfer
  • Perfect for anaerobic processing in a low-humidity nitrogen or argon environment
  • Dual hose barb fittings simplify connection to vacuum pump to allow rapid air removal
  • Safe for intermittent vacuum below 29"; damage to welds may result under continuous full-vacuum pressure.
  • 1" thick reinforced acrylic walls support full vacuum (to 29.9"Hg)
  • Includes: leveling feet, two port caps, dual valves for connection to vacuum pump and backfill gas source, pressure gauge and relief/bleed valve.
  • Order gloves and vacuum/purge controls separately
  • NOTE: The gloves cannot be used under negative pressure since the port covers must be shut while the chamber is under vacuum. The chamber must be back-filled to atmospheric pressure before materials inside the glovebox can be handled.

Important Application Notes for Series 210 Glove Box

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.

  • Duo Seal Vacuum Pump

    Welch DuoSeal Vacuum Pump has a belt-driven, oil-seal design that extends durability and service life even under harsh operation conditions.
  • Vacuum Control Module

    This automatic Vacuum Control Module is especially important in testing or processing applications that require sustained exposure to a precisely regulated vacuum level it helps extend the service life of your vacuum pump by allowing continuous pump operation.
  • Vacuum Connection Kit

    All Turnkey Connection Kits include a solenoid vacuum valve and all necessary hosing, clamps, adapters and other connection hardware for the specified application. Draws power from the Vacuum Control Module.
  • Standard Duty Dry Vacuum Pump

    Vacuum Ovens by Thermo Fisher are compact dry vacuum pump runs quiet and continuously. These pumps are suitable for applications for dry, moist or ethanol vapors.
  • Stainless Steel Glovebox on Automatic Height Adjusting Table with N2 Generator

    Gloveboxes can easily mount to an automatic height adjusting table (28”-43”H). Ideal for workstations with sensitive equipment that undergo frequent height adjustment. A compact Nitrogen generator requires only a compressed air supply for continued nitrogen gas supply.
  • Neoprene Accordion Sleeve Assemblies

    Neoprene accordion sleeves with nitrile gloves allow fast glove replacement without removing sleeve; rigid neoprene sleeve resists blow-back (other glove styles available).
  • Welch Rotary Vane Vacuum Pump

    This Rotary Vane vacuum pump offers high water vapor tolerance, light weight and high vacuum performance, making it ideal for many laboratory uses.
  • PC-Based Vacuum Control with Data Logging

    The eVAC Digital Vacuum Controller provides highly flexible control over vacuum levels by incorporating an electronically activated bleed valve, which adds the capability to reduce the applied vacuum.
  • Dual Purge™ and NitroWatch™ Work Together to Fully Automate RH Control

    Terra's Dual Purge™ and NitroWatch™ operate in tandem to precisely and automatically control the flow of nitrogen and maintain a preset humidity level (from ambient to 0% ± 1.5% RH), no matter how operating conditions may change.
  • Data Logging with 113,000 Readings at User Defined Intervals

    Terra's Smart® IsoDry® Nitro-Watch™ logs RH, temp, door open/close, purge on/off, and sensor removal/attachment. The max data file size is roughly 4 MB or 113,000 readings. This is approximately 32 hours of data when logging at 1 second intervals, 2 weeks at 10 second intervals, 6 weeks at 30 second intervals, or 12 weeks at 1 minute intervals. When the system reaches the 4MB limit, data begins to wrap, overwriting oldest data with new.
  • Plug & Play Data Logging

    Plug in a USB flash drive to your Smart® IsoDry® Nitro-Watch™ to transfer data in .CSV format. No software required.
