I need your help about my project.
I will do fungal fermentation. Previously I used erlenmeyer 500 ml for the process but unfortunately there are many people in my lab use the same volume of erlen so there are't enough of erllen for my project. I should modify and I think I could use Duran bottle 500 ml.
Since the bottle neck is wide, can I used the original cap and cover it with parafilm to avoid contamination? Or I should put cotton plug and close it with alumunium foil?
Thanks for your advice!
