The evaporator#1 glovebox is leaking from the gloves, around the ports, and the base (possible more places).  It is evident that there were holes on the gloves.  When the glovebox is purged with Ar gas, one can feel that the gas is blown out from the base.  

Solutions:

New gloves are ordered from RENCO Co. (PO#TR189708). 

New seals & glove port rings have been implemented. 

More need to be done...
