[Histonet] Rotring ink for marking arteries and veins

[Sarah Jones]

Hello Netters,
  I had a researcher come in and ask about Rotring ink.  It was used in
a procedure to inject and mark the arteries and veins with different
colors.  I know Polysciences has the Batson's Anatomical Corrosion Kit. 
I spoke to Pam Marcum at Polysciences and she said the Batson's is not
Rotring ink.  She thought Rotring ink may be a tattoo ink.  Does anyone
know what Rotring ink is, where it can be purchased, and how it would be
diluted to inject into the vessels?  
Thanks, Sarah
