Naphrax is a synthetic resin. Because of its surface contact with the diatom frustules, its resolution qualities are equivalent to that of a mountant with a refractive index of 1.74 at the least.
This Naphrax has Toluene added for ready to use resin upon arrival. We offer both, Naphrax Export (no Toluene added) and Naphrax with Toluene ready to use (this may have shipping restrictions)
