Normally they are blow dry with nitrogen at a low rate into a knock out. And yes this is technically evaporation but the typical amount is very small. You can cool the knock out if you want to try and collect the bulk of the liquid.

Hi, all,

 

I am searching for alternatives on behalf of a research group whose current practice is to invert columns with wet chromatography media over old shipping cans in fume hoods.  The issues are:

  • that the media is not readily transferable when it is wet
  • that the open can will be characterized as a violation by an environmental inspector since this is disposal by evaporation into exhaust.

Any alternatives you've encountered or experiences with environmental inspection verdicts on these would help immensely.

 

Thanks,
