The pill or flea as they are known have a tough teflon coating.
I used them in experiments using extremely sensitive transition metal catalysts for analysis metathesis reactions for the preparation of DNA intercalators from dialkenes.
However, I have seen some stained from chemicals but in general they are unreacted. They could react with some of the indicator dyes we use.
On the other hand, if they are cheap cheap ones from China...
