Graphite Platform Set (pre-insert) (10)

L'vov Platform Set (pre-inserted). Made from high purity, high density graphite, these tubes exhibit an extremely low "Coefficient of Thermal Expansion" (CTE), ensuring less stress placed upon the pyrolytic coating, thereby increasing their usable lifetime. Tube and platform CTE's have been closely matched, reducing the possibility of the platforms releasing from the walls. Thermal conductivity is uniform to allow for consistent, even heating, not only within the tube, but from tube-to-tube as well.
