VBF-1700X-BSA40 Bottom Loading Box Furnace with 40L Capacity, Continuous 1700°C Operation, and Electric Motor Sample Platform
The VBF-1700X-BSA40 is designed for laboratories requiring precise high-temperature thermal processing with rapid heating and cooling cycles. Its bottom-loading design facilitates easy and safe sample handling, driven by an electric motorized platform that minimizes operator exposure to extreme heat. This furnace is ideal for applications demanding continuous operation at temperatures up to 1700°C, with short-term capability reaching 1750°C for up to one hour.
The heating chamber is cylindrical, measuring 400 mm in width, 340 mm in depth, and 300 mm in height, providing a nominal volume of approximately 40 liters. The furnace employs ten Kanthal 1800°C grade molybdenum disilicide (MoSi2) heating elements, ensuring uniform and efficient heating. The unit features a two-layer casing with an air cooling gap, and the outer casing can optionally be constructed from stainless steel for enhanced durability.
