Hi,

The hazardous waste has to be marked with full names.

DAPI appears to be problematic.

Its right complete name is

4',6-diamidino-2-phenylindole

It is usually sold as dihydrochloride salt (but DAPI does not mean dihydrochorine :)).

Please, do not bring down to the storage room unknown waste - at least do explain to "ongelmajäteyhdyshenkilö" (Harri Elamaa) how you have tried to find out what the waste contains.

Regards

Pekka
