VBF-1600X-L72 1600°C 3-Zone Heated Bottom Loading Box Furnace with 72L Chamber and Precise ±3°C Uniformity
The VBF-1600X-L72 is designed for laboratories requiring rapid thermal processing with precise temperature control in a spacious environment. Its bottom loading design facilitates safe and ergonomic sample handling, especially for heavy or bulky materials, while enabling fast heating and cooling cycles essential for advanced material synthesis and heat treatment workflows.
This furnace achieves continuous operation at temperatures up to 1600°C, with a short-term capability of 1700°C for up to one hour. The heating chamber measures 400 mm wide by 400 mm deep and 450 mm high, providing a nominal volume of approximately 72 liters. Within this chamber, a uniform heating zone of 300x300x300 mm maintains temperature stability within ±3°C, critical for consistent experimental results.
