Our S-Series blocks are designed for use with Sirona’s inLab and MC XL milling systems. For ultimate compatibility, our S-series blocks all have a type B mandrel, and are marked with a bar code and a *z number on the block which is read by the Sirona milling equipment to indicate precise material density.  Crystal Zirconia blocks are sold to dental labs only in the US at www.dentalzirconia.com.
