Item Number: EQ-VGB-4A
Transported by LTL Freight (Truck)
EQ-VGB-4A is a heavy duty stainless steel glove box with Airlock Chamber, Gauges and vacuum Flanges, which allow glove box operate under vacuum 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

  • Case Material: Made of 11 gauge (3mm thickness) 304 stainless steel sheet which provide heavy duty structure for vacuum
  • Dimensions: 1120mm(L) x 740mm(W) x 900mm(H)
  • Max. Positive Pressure: 810 Torr (1.1 atm)
    • Note: Gloves cannot work if pressure is higher than 810 Torr
  • Max. Vacuum Level: 0.5 Torr
    • Note: Stainless Steel case may deform at higher vacuum level
Air-lock Chamber with Air lift
  • Dimensions: 360mm(ID) x 435mm(L)
  • Max. Vacuum Level: 0.05 Torr 
Transparent Front Panel
  • Dimension: 1040mm(L) x 405mm(W)
  • Removable for putting in devices
  • 3mm thick plexi-glass
Vacuum Gauge and Valves
  • One vacuum gauge is installed in Air-lock chamber
  • 1 set of 1/2" barbed needle valve and 1 KF-25 Vacuum port built in Air-lock chamber
  • 2 sets KF25 port are built on the back of glove box chamber
  • 3 sets KF40 port are built on the back of glove box chamber for connecting to gas purification system
  • On the Glove Box Chamber On the Air-lock Chamber
Leakage Rate in Glove Box Chamber < 3 Torr/hour
Power Extension

  • Glove Port size: 190mm(Dia.)
  • 8'' Butadyl® Gloves included (with increased stretching, bending ability and tear strength, and offer strong resistance to aromatics, hydrocarbons, solvents, fats, and acids)
  • Clamps and sealing flanges included
Vacuum pump and fittings (Optional) Vacuum pump and fittings are not included. (Please click on the picture below to order separately) 
  • One year limited warranty with lifetime support
  • Rusting and damage due to improper storage condition or maintenance is not covered by warranty
  • Gloves are consumable items and are not covered under warranty
Operation Manual  
Application Notes
  • Always check the joints, gloves, sealing elements, and pipelines for air-tightness before and during the operation
  • Corrosive gases are prohibited as they will damage the sensors
  • The inlet and outlet of the Air-lock Chamber must not be opened at the same time to prevent contamination by the external gas
  • By closing the vacuum flange, the glove box can be vacuumed by mechanical pump upto 0.5 torr before filling inert gas, (moisture can be below 180 ppm and oxygen below 200 ppm). Then you can save at least 1-2 tank of inert gas from purging at each operation
  • Click here to order N2 gas generator if you don't have gas tank in your lab
  • Please call or email us to get price and lead time for multi-pins feed through 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 torr/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 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 Trace Oxygen Analyzer (0 - 1000ppm) with KF40 & Flow Housings
  • 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 moisture filter or a Recirculating Gas Purification System for purging
  • Note: For Li-ion battery research, please order VGB-5, VGB-6, or VGB-7 to achieve humidity < 10ppm
  • The cleasing rate of O2 will vary depending on the type of purging gas used, for faster cleasing of chamber Nitrogen gas is preferred over Argon gas due to its lighter mass.
