[Histonet] Tissue Tek VIP 5 processor

[Rene J Buesa]

If by green discoloration you mean that it seems as if the metal is greenish?
If that is the case maybe so much scrubbing may have removed part of the nickel platting of the retort and a copper shim is becoming evident (I think).

Subject: [Histonet] Tissue Tek VIP 5 processor

We have had our Tissue Tek VIP 5 floor model processor for five years. Here is a little background: We are an animal diagnostic facility, there is no formalin in the processing cycle, and we perform weekly cleaning/maintenance. The retort chamber is wiped down every day after the processing and cleaning run. However, the retort chamber has recently had a green discoloration form on the sides and bottom and I'm not sure what would be causing it. Any ideas?

Thanks,

Jamie
