VBF-1600X-B Vertical Atmosphere Controlled Furnace with 11″ I.D. x 13″ Chamber, Automatic Bottom Loading, and 1600°C Max Temperature
The VBF-1600X-B furnace is engineered to support precise sintering and annealing processes for semiconductor wafers and advanced materials requiring controlled atmospheres. Its vertical design with an 11-inch internal diameter and 13-inch length sealed chamber accommodates samples up to 50 kg, facilitating efficient bottom loading via an automated motorized mechanism. This setup enhances operational safety and ease of sample handling in vacuum or inert gas environments.
Operating temperatures range continuously from 800°C to 1600°C, with short-term capability up to 1700°C for less than one hour. The furnace achieves vacuum levels down to 10⁻² torr using an integrated mechanical pump and features water-cooled stainless steel vacuum flanges to maintain seal integrity. Temperature uniformity is tightly controlled within ±0.5°C, supported by a programmable Eurotherm controller with PID and auto-tune functions, ensuring precise thermal profiles for complex thermal cycles.
