Fig.2 CZ Growth

• Two fixtures made of stainless steel are included for mounting quartz tubes. 
  • Half-end quartz tube: 20 OD×16 ID×150 H, mm
  • Half-end quartz tube: 15 OD×11 ID×150 H, mm
• Note: SS fixture may be oxidized at T > 800°C
• For volatile elements, the sample shall be sealed in a quartz tube using a VTS-1 tube sealer. 
  
• For Bridgeman growth w/o atmosphere control, please consider our OTF-1200X-S-VT-BMGH or remove the quartz tube for easy sample installation

•  Note: It is the customer's responsibility to create a suitable thermal gradient for crystal growth.

Water Chiller
(Optional)

• A water chiller is required to prevent top flange overheating but it is not included in the standard package.
