Re: Histobath


We disinfect our nitrogen flask every night.
We also have a flask we only use to decant nitrogen into freezing
sprays.  These sprays are used by dermatology on warts.  Our worry
was that virus particles from specimens could contaminate the flasks
and then infect the dermatology patients.
