3. Quick user guide for glove box (OMNI-LAB SYSTEM) Glove box pressure control Antechamber evacuate/refill procedure Kyung-Wan NamJun Wang If there is any question, please contact Kyung-Wan Nam (knam@bnl.gov, #3202) or Jun Wang (junwang@bnl.gov, #2661).knam@bnl.govjunwang@bnl.gov Only the mini antechamber can be used! Important ▪ Everything that you transfer into the glove box needs to be dried first. ▪ Chemicals (except electrodes and electrolytes) are not allowed to be transfer into the glove box unless authorized. ▪ Please keep the glove box clean and neat. Temporarily used tools and samples should be removed from the glove box after the use. This glove box can only be used for assembling/de-assembling lithium-ion battery cells.  Before using, the low limit pressure needs to be set to -1.0” by pressing PRESSURE LIMITS key on the touch screen first then DEC or INC key to adjust pressure shown on the right.  The work pressure can be adjusted between the low and high pressure limits by footswitch.  When finished, low limit pressure should be set back to +1.0”.  When transferring tools and materials into glove box through mini antechamber, both the antechamber doors must be closed!  The antechamber atmosphere can be made inert by using one of the following combinations of evacuation & refill times and cycles: - 1 cycle, 10 to 15minutes or - 2 cycles, 3 to 5 minutes each, or - 3 cycles, 1 to 2 minutes each Evacuate/refill valve for mini antechamber
