[Nhcoll-l] Diluting ethanol

[Dirk Neumann]

... I simply used a big plastic rod for stirring our 60 litre drum, very simple and effective ...

All the magnetic stirrers I have seen are relatively small and would have little to no effect in that volume of fluid.  We have had great success with air bubblers (simply placing a tube with a weight on the end connected to an air source) in mixing alcohol solutions.

Subject: [Nhcoll-l] Diluting ethanol

Hi all,
I just wanted to double check if anyone has used magnetic stirrers for large volume (~25-100L) to dilute ethanol for use in collections?
If so, what brand have you used, and what are the pros and cons of these units?
Thanks,
Anja
