How frequently must pharmaceutical equipment be re-passivated?
May 13, 2010
In the pharmaceutical industry, passivation of stainless steel vessels has been a standard. Is there any recommendations for how often passivation should be performed?

Dear Mr. Reilly,
It is important to ensure the passivation quality of the SS vessels and reactors periodically.
Some meters are available in the market to check the passivation quality.
