EVAP1:  Checked seal and no visible deterioration was observed.  Oil level in roughing pump was good.  Circulated argon to observe functionality of the gloves and to check appropriate gas flow. 

EVAP2:  Visually inspected the connections at the back of the evaporator.  A loose connection had been observed on the previous day but fixed.  Roughing pump running well and system operational.  The door seal could not be checked but it is working properly as evidenced by the fact that the evaporator was in use. No major maintenance required at this moment.
