CZOCHRALSKI FURNACE (CZ) Puller

Czochralski furnace for single crystal

The Czochralski furnace CZ Puller, from ECM Lab Solutions, come in a variety of sizes, heating power elements and intensities. The heating technology of this czochralski furnace can be inductive or resistive depending on the process requirements. The size of the crucible can reach 400 mm diameter and have a working temperature up to 2300°C.  Czochralski furnaces are all equipped with the precise and stable Cyberstar pulling head having a conversion rate of 0.01 to 100 mm/h translation speed. Full monitoring and control of the growth is provided with the inclusive intuitive and user friendly Cyberstar pulling software. This allows for the fully automatic growth of the crystal after the dipping of the seed which is based on predefined crystal geometry, created by the user, in the dedicated geometry definition window of the software. The design variety of the czochralski furnace makes it ideal for laboratory use, as well as, for universities and R&D centers.
