High temperature melting vacuum crucible furnace details

The 1250C vacuum crucible furnace is designed for sintering ceramic parts and components in the laboratory.

The crucible furnace has a unique ceramic fiber insulation around the furnace chamber, providing excellent uniformity and energy efficiency.

The heating element is embedded in the insulating material to maximize the transfer of heat to the chamber. The highest temperature can reach 1250°C
