Air-free synthetic chemistry

          
One N2 filled MBraun glovebox (O2<1 ppm, H2O<1ppm);  Seven Schlenk lines (4 for wet synthetic chemistries inside fume hood and 3 for high vacuum operation)
 
Electrochemistry characterization lab
This lab equipped with an Argon filled MBraun glovebox (O2<1 ppm, H2O<1ppm) with five electrical feedthroughs for electrochemical testing inside the glovebox. Four PAR 273A/273 potentiostat/galvanostat are located both left and right of the glovebox and one Autolab PGSTAT 302 potentiostat/galvanostat is located far right from the glovebox, behind the PAR 273A rack. All of them can be used the same time for electrochemistry testing inside the glovebox.  Also on the very left, there is  a Faradic cage, another PAR 273, a PINE RRDE system used by Prof. Koppang for teaching and aqueous solution electrochemistry. Very far left in the picture is one of the fume hoods for air sensitive chemistry with high vacuum Shelenk line inside.
