Vacuum pump and fitting assembly (click to review details)
VGB-3 is a middle size heavy-duty stainless steel glove box with Airlock Chamber, Gauges and vacuum Flanges, which allows the glove box to vacuum the chamber to remove moisture and oxygen without expensive inert gas purging, It is an ideal tool for material and chemical researchers to process air sensitive materials and solutions.

Glove Box Chamber
containment chamber VGB-4P
  • Case Material: Made of 11 gauge (3mm thickness) 304 stainless steel sheet with support frame and plastic paint, which provide heavy duty structure for vacuum
  • Dimensions: 780mm(L) x 700mm(W) x 650mm(H)
  • Max. Pressure: 810 Torr (1.1 atm, absolute) ( When the doors are closed.)
  • Max. Vacuum Level: 0.05 Torr
  • Note: Stainless Steel case may deform at higher vacuum level
Airlock Chamber

  • Dimensions: 240mm(ID) x 260mm(L)
  • Max. Vacuum Level: 0.05 Torr 
  • Air-lock Chamber Size Air-lock Chamber & Tray
    Air-lock chamber VGB-4P  slip tray
Vacuum gauge and valves
  • Two vacuum flanges are included for glove box to achieve vacuum to remove moisture and oxygen without expensive inert gas purging
  • Two KF-25 vacuum fitting ports with Quick Clamps are installed in the back for connecting vacuum pump, electric/fluid feed-through, gas circulating/purifying system, or other testing equipment
  • G1/4" gas port
  • On the Glove Box Chamber On the Airlock Chamber
Leakage Rate in Glove Box  < 6 Torr/hour 
Power Extension
  • One extension socket (Max power 1500W) is installed in the glove box main chamber.
Power Input Socket  External Power Cord Internal Power Extension
  • Note: 110V power cord was included for immediate use. (For use under 208~240V power supply, no plug will be included) 

  • One pair of Latex Gloves is included for immediate use
  • Clamps and sealing flanges included
  • Optional: You may order 6'' Butadyl® gloves here because they have:
    • Increased stretching, bending ability, and tear strength
    • High effectiveness when vaporized hydrogen peroxide (VHP) is present
    • High resistance to aromatics, hydrocarbons, solvents, fats, and acids
    • Resists ozone
    • High static dissipative qualities
Vacuum pump and fittings (Optional)
  • The vacuum pump and fittings are not included. (Please click on the first picture below to order separately) 
  • We may add a customized flange to connect a tube furnace to the glove box
  • You may order pressure controller to keep inert gas pressure constant ( click Pic below right 2)
  • One year limited warranty with lifetime support
  • Rusting and damage due to improper storage condition or maintenance are not covered by warranty
  • Gloves are consumable items and are not covered under warranty
Operation Manual  
Application Notes
  • By closing the vacuum flange, the glove box can be vacuumed by a mechanical pump up to 0.05 torr before filling inert gas, (moisture can be below 180 ppm and oxygen below 200 ppm). Then you can save at least 1-2 tanks of inert gas from purging at each operation
  • Please call or email us to get the price and lead time for multi-pin feedthrough on the glove box if you need to measure the sample inside the chamber, MTI's technician can provide a solution with no impact on sealing (leaking rate less than 6 torrs/hour) in an affordable price. Please click the picture below to see our perfect customization: 
16 pins electrical feed through outside the glove box
(4 pins per one feed through)
16 pins electrical feed through inside the glove box
(4 pins per one feed through)
  • You may choose the humidity and oxygen analyzer below at extra cost  to monitor gas humidity and oxygen content inside the glove box
Precision Humidity Analyzer  Trace Oxygen Analyzer (0.01 -3000PPM ) with KF40 Connector
  • The humidity inside the glove box can be controlled by using either manual purging system or Gas Purification System. Please see our experimental results below:
    • Humidity Range 4~5% Rh: Can be achieved after manually purging the system for 6 cycles by using N2 gas supply tank
    • Humidity Range < 2% Rh: Please use either gas supply with 99.9999% gas purity with a moisture filter or a Recirculating Gas Purification System for purging
Shipping Dimensions 50" x 40" x 37" 
Shipping Weight 240 kg (520 lbs)
