- Hi all, Here is a pic of my N/S still, I still don't know how it will
perform with the return into the column. My first wash is yet to
ferment out. I have 16 scrubbers in the 1 metre section below the
return. Just doing a distilled water run with the scrubbers in and the
take off tap wide open I was collecting at the rate of 28 mL per
minute, I'm just hoping that is an indication of the purity I will get!
Regards to all,
