EQ-VGB-3 is a middle size 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.
SPECIFICATIONS
Glove Box Chamber
•Case Material: Made of 11 gauge (3mm thickness) 304 stainless steel sheet with sport frame and plastic painting, which provide heavy duty structure for vacuum •Dimensions : 780 mm (L) x 700 mm (W) x 650 mm (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
•Dimensions : 240 mm (ID) x 260 mm (L) •Max. Vacuum Level : 0.05 Torr
Air-lock Chamber Size
Air-lock Chamber & 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
○ Do not operate under vacuum status. Vacuum process is used for purging the glove box chamber before operation.
•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

Leakage Rate in Glove Box Chamber
< 6 Torr/hour
Power Extension
•One extension socket (Max power 1500 W) 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)
Gloves
•One pair of Latex Gloves are 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 ○ Resistozone ○ High static dissipative qualities
Vacuum pump and fittings (Optional)
•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 •We may add ultrasonic mixer head on top of glove box upon request at extra cost.
Warranty
•One year limited warranty with lifetime support •Rusting and damage due to improper storage condition or maintenance is not covered by 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 •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
•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 < 10 ppm
