Most of the synthesis experiments are done using same procedure if your lab has no well organized schlenk-manifold. It is much easier and cheaper option.
in order for the gas from the balloon to replace the air in the system, it is necessary that the air from the system escape into the atmosphere just through this needle
Just use cable ties to attach the balloon to the needle.
Why cut the balloon?
I did this all through grad school. But I didn't cut the balloon, and held it to the needle with rubber bands.
Dont you have a schlenk-manifold or something? I would not call this "inert" atmosphere...just slightly better than regular atmosphere
Agreed

why put the needle at the 2:30? is it necessary?
