400C Max. Zone Melting Furnace for Directional Solidification and Purification - OTF-1000XCBZ-AB

OTF-1000XCBZ-AB is a 400°C Max zone melting system that is equipped with a touch screen for ease of control. Such a system is widely used for metallic material directional solidification, purification, and single crystal growth.

Specifications:

Feature	Vacuum/Atmosphere protective environment for samples. Maximum travel distance: 450 mm.  Single heating element for a maximum temperature gradient. Adjustable temperature gradient for versatile materials. (~50°C/cm) Moving/Pulling Speed: 0 - 55mm/Hr adjustable. Ideal for low-melting-point material directional solidification, purification, and single crystal growth.
Heating Module	The Heating Module is made of a resistance wire ring heater, one RTD sensor for temperature control, two extra RTD sensors for temperature monitoring, two cooling air knives. The positions of air knives are adjustable.  Max. working temperature is 400ºC The ID of the ring heater is 32 mm The heating zone length is 40 mm The heating module is fixed on a linear module to achieve accurate verticle movement. The spare heating module is available upon request at the extra cost
