Specifications

 OTF-1200X-SCB is a compact crystal grower for both CZ and Bridgeman methods up to 1100°C. The precision pulling & rotation mechanism is built on a compact two-zone vertical tube furnace with 2" quartz tube and vacuum-sealed flange, which can pull a single crystal from a melt in the crucible via seed or move down to grow the crystal via a capillary. Note:  Upgrade to a vacuum-sealed quartz tube and a hermetic pulling mechanism since Jan 5, 2021, which is compatible with volatile materials and growth in a controlled atmosphere.
