Sue,
I know it is a pain, but you should send the Osmium back to the vendor.
They probably have a formal complaint system and would like the item so
that they can try to resolve the issue. If you are getting a replacement,
see if they have a different lot number than the one you received.

We are experiencing a recurrent problem with the osmium tetroxide
crystals going into solution (4g/100ml of MilliQ distilled water or
glass distilled water). The solutions are cloudy, not clear as they
have always been in the past. We have tried changing glassware,
checked the water etc. The source of the osmium is a very reputable
company that we have always gotten the OsO4 from in the past and they
are willing to replace our osmium stocks & solutions but if we can
avoid shipping all of this hazardous material we would like to. Does
anyone know if filtering the cloudy OsO4 suspension would be an
option?
Thank you,
