Dry Glove Box with Humidity Purification System (H2O < 1 ppm) for Li-Ion Battery Research - VGB-7H2-LD

In stock
Item Number: VGB7H2
Transported by LTL Freight (Truck)
VGB-7H2 is a dry glove box with automatic moisture purification system, which can provide a dry gas environment with moisture lower than 1 ppm. It is a cost-effective solution for Li-Ion battery research at low cost because most Li-ion battery's electrolyte is sensitive to moisture, but not oxygen. One slidable Sample Shelf is built on top inside glovebox to make operation easy.
Working Voltage 220V 50/60Hz, Single Phase (110V AC is available at extra cost)

Purification System
  • Automatic moisture remove to < 2 ppm (Li-Ion battery assembling requires <11 ppm moisture)
  • Precision Humidity Analyzer with KF25 Flange (0-999 ppm) is installed on the Purification System with accuracy  +/-0.1 ppm
  • Large capacity moisture filter built-in bottom of a mobile cart, which can soak moisture up to 1.5kg
  • Regeneration Temperature Controller is built-in for automatically regenerating the filter
  • The automatic pressure control system is built in to keep the pressure at a constant level
  • 6" color PLC touch panel is included which can set and display the humidity and pressure level. (Please click the first picture below for details)
  • The control panel is removable, which can be placed anywhere for easy operation          
Purification Pipeline 304 stainless steel, KF40 port
Vacuum pump
  • Heavy-duty vacuum pump with filter is included for faster vacuum and removing moisture
  • Stainless steel vacuum bellow and valve are included


Gasses Requirement
  • Working gasses: Atmospheric Gases, N2, Argon          
  • Regeneration Gas: 95% N2 + 5%H2
  • One float meter built on the front of a mobile cart for accurate gas filling
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
  • The power cord was included (For use with 208~240V power supply, no plug will be included) 
  • 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
Application Notes & Warnings
  • The interconnections between the glovebox chamber and the gas purification system must be unimpeded during the purification cycles. 
  • The use of corrosive gasses is prohibited as they will damage the water sensors.
  • Regularly perform regeneration to maintain optimum purification efficiency. 
  • The H2O 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. 
  • 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 purification pipeline.
