Subject: [Histonet] disposal of 3, 3'-Diaminobenzidine Tetrahydrochloride (DAB)

Dear HistoNet Community,


Recently we purchased an immunostainer . In the waste from the immunostainer there are small quantities of 3,3'-Diaminobenzidine Tetrahydrochloride (DAB) in the amount of e 35-38 mg per 20L of waste.
I want to hear from the community how you dispose of it. Do you use any of the methods available (permanganate/sulphuric acid and hydrogen peroxide/HRPA) to convert DAB to non-mutagenic compounds?

Thank you,

Iliana Dimitrova, RT, B.Tech., M.Sc.
