Table-top bottom loading furnace with stirring capability
Achieve precise thermal processing with controlled heating and optional stirring, ideal for creating consistent, high-quality materials in research, metal processing, and ceramics.

Heats and Controls Temperature for Material Processing
The BLF1700 from Across International is a motorized, table-top bottom loading furnace designed for demanding thermal applications needing precise control. Utilizing Molybdenum Silicide (MoSi2) Type 1800 heating elements, it achieves temperatures up to 1700°C, ideal for processing ceramics, metal alloys, and synthetic diamond materials. With a Eurotherm multi-segment PID controller, it ensures an optimum thermal process, minimizing overshoot. The motorized bottom elevator hearth enhances operational ease, while optional stirring facilitates improved material uniformity. Designed with high-quality Mitsubishi alumina fiber insulation, it reduces heat loss, ensuring energy efficiency. This furnace is suited for research and development, industrial, and educational settings, providing reliable temperature control crucial for metallurgy and material science.
