Vacuum pump and fitting assembly (click to review details)
VGB-4A-LD is a heavy duty stainless steel glove box equipped 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

  • Case Material: Made of 11 gauge (3mm thickness) 304 stainless steel sheet which provides 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
Airlock Chamber with Air Lifting
  • 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 plexiglass
Vacuum Gauge and Valves
  • One vacuum gauge is installed in airlock chamber.
  • 1 set of 1/2" barbed needle valve and 1 KF-25 Vacuum port built in airlock chamber.
  • 1 KF40 port and 2 1/2" barbed needle valves are built on the chamber side of the glove box.
  • 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.
Leakage Rate in Glove Box Chamber < 3 Torr/hour
Power Extension
  • One extension socket (Max power 1500W) is installed in the glove box main chamber
  • Power Input Socket  External Power Cord
  • Note: 110V power cord was included for immediate use. (For use with 208~240V power supply, no plug will be included.) 
  • Glove port size: 190mm in diameter.
  • One pair of 8" Latex Gloves are included for immediate use.
  • Optional: You may order a pair of 8'' Butadyl® Gloves  (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) 
 110V / 220v

  • 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
  • Corrosive liquid (such as LiPF6 electrolyte) must be remain sealed in a container inside the glove box. Otherwise, liquid vapor may condense and corrode the steel chamber and the purification pipeline.
  • The H2O & O2 removing rate is largely dependent on the type of purging gas used. For faster chamber purging process, Nitrogen is preferred over Argon due to its lighter mass.
  • By closing the vacuum flange, the glove box can be vacuumed by mechanical pump up to 0.5 Torrs 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.
  • Please call or email us to get a 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 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 feedthrough)
    16 pins electrical feed through inside the glove box
    (4 pins per feedthrough)
  • You may choose humidity and oxygen analyzer below at extra cost  to monitor gas humidity and oxygen content inside the glove box
  • 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 by 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
  • You may order a purification system to remove H2O < 1 pmm, and O2 &H2O < 1 ppm
    Automatic Recirculating Moisture & Oxygen Purification System for Glove Box (O2 & H2O < 1 ppm)- EQ-RMP-2-LD
Automatic Recirculating Moisture Purification System for Glove Box (H2O <2 ppm) - EQ-RMP-1
