fina precip

Did anyone ever have a red precipitate form on the bottom of their fina weeks after it was made? The only thing I think I did was use the same needle to draw out of a test vial and the fina vial, and maybe some of the test oil got in there (although it's not red, maybe the mix made it red). I don't know what blood looks like in a vial, and would have no idea how it would get in there, since I use different gauge and length needles for drawing and for injecting. But OMG, if it's blood I guess that means I gotta do the whole oven sterilizing method. Has anyone seen this before?

I wouldnt worry, you're find. It is just some of the binders that made their way through the filter. Mine usually does the same thing

Thanks Skrilla! That was the response I was hoping for, but I was not sure.
