XMark Ink Shield fixative spray

XMark Ink Shield is a quick drying fixative spray, applied after a specimen is marked with a dye. It forms a protective layer on the marked surface whilst still allowing the tissue processing reagents to penetrate the tissue.


  • Can be used with all dye colours and on all specimen types.
  • Specially designed for use with the XMark range and ensures that specimen margins, marked with Xmark dyes (including yellow, orange and red), are durable and unaffected during tissue processing.
  • Reduced leaching of dyes helps reduce the clogging up of the processors, eliminating potential failure and downtime.
  • Enables strong adhesion of dyes on particularly fatty tissues.
  • Clear.
