Yamato muffle furnaces are recognized for their durability and tightly sealed doors which is of utmost importance when the furnace reaches their maximum temperatures of over 1000°C. The FO Series represents the standard type of muffle furnaces that use a microprocessor-controlled thermoregulator characterized by excellent repeatability. They are used for high temperature applications such as fusing glass, creating enamel coatings, ceramics, soldering and brazing metals, alloying, fusion, heat treating, melting, annealing, metallurgy, mining, environmental testing, pharmaceutical development, in R&D and more.
