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.
SPECIFICATIONS
Glove Box Chamber
•Case Material : Made of 11 gauge (3 mm thickness) 304 stainless steel sheet which provide heavy duty structure for vacuum •Dimensions : 1120 mm (L) x 740 mm (W) x 900 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

Power Extension
•One extension socket (Max power 1500 W) 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 under 208 ~ 240V power supply, no plug will be included)
Gloves
•Glove Port size : 190 mm (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 first picture below to order separately)
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 •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
•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
