LC-HVB-250V High-Temperature Vacuum Drying Oven, 250 L and 7500 W (CAT#: STEM-BC-3598-ZJF)

The LC-HVB-250V is a 250 L high-temperature vacuum oven for large-volume processing. It provides controlled drying and heat treatment for sensitive or oxidation-prone materials. Reduced pressure accelerates drying while allowing lower oxygen exposure. The chamber can receive inert gas through the standard valve and flow-control assembly. A 7500 W heating system provides temperatures from ambient plus 20°C to 350°C. PID control and a high-information LCD interface support precise and visible operation. The reinforced SUS304 chamber provides chemical resistance and structural strength. The V-series configuration requires an external vacuum pump, cooling-water connection, and evacuation before heating.
