[Histonet] RE: Disposal of Ventana DAB waste

[Emma JONES]

Hi Joe,=20
A specific answer to your question, regarding Ventana not DAKO waste. =
The volume of  DAB in the waste is very small and diluted considerably =
by the other solvent free solutions.
It can be thrown down the sink, washed down with plenty of water.

However there is a technique for deactivation of DAB which is applicable =
to any form of DAB waste.
Prepare a 2 mol/litre H2SO4 solution, and a 0.2 mol/litre KMnO4 solution
	- Add 50 ml of each solution to the Ventana DAB waste to be destroyed
	- Let the 3 solutions react overnight
	- Discard the solution into a regular sink, and wash down with plenty =
of water.

Hope this is of use,=20
Best regards
Emma
