Standard STF series furnaces cover a range from 1200°C to 1300°C, using only wire heating elements for the process.
STF series enable the user to heat up to 1300 Degrees Celsius, as well as to operate the furnace with multiple zones of different lengths.
STF series ensure perfect temperature uniformity with quick and easy replacement of the reactor used.
