Features

• A water-cooled copper hearth has 4 small cavities for alloy melting of  4 x 8 g up to 2500ºC max
• The central tube holder allows refractory tube seals, such as Ta, Nb, and Mo.
• 6.6 " ID (168 mm) quartz chamber for observation and protection. 
• Easy electrode tilting and height adjustment
• Compact footprint: can put in a standard Ar gas glovebox with a purification system
• The power and water feedthrough will be provided for the glovebox version. 
• Vacuum suction casting 4 mm Dia. The sucking force is generated by evacuating the bottom cold copper casting mold. This results in rapid solidification of the melt which is ideal for reducing the shrinkage cavity defects.
