Do I need nitrogen purge?
Only if your process requires an N2 environment in the process chamber. The nitrogen purge can reduce air turbulence in the chamber. All spin coating models come standard with a height adjustable syringe holder and diffuser with nitrogen connector, that you can simply connect to your nitrogen supply (ID 4mm – OD 6mm tubing). But you hook up the nitrogen only if you want to.
