VBF1200X 1200°C Top-Loading Muffle Furnace with 9.5″ Diameter x 8.6″ Height (9L) Chamber and PID Controller
The VBF1200X furnace is designed for laboratory sintering tasks requiring precise temperature control within a spacious 9-liter chamber. Its top-loading design facilitates easy placement and removal of ceramic parts and components, making it suitable for materials research and small-scale production workflows that demand uniform heating up to 1200°C.
This furnace operates with a maximum continuous temperature of 1100°C, with the capability to reach 1200°C for short durations up to 3 hours. The heating elements are made from a molybdenum-doped Fe-Cr-Al alloy, ensuring durability and consistent performance. High-quality ceramic fiber insulation minimizes heat loss and improves energy efficiency during operation.
