STF Series Tube Furnaces

LABTHERM STF series tube furnaces are tube furnaces that could be used when laboratory experimentation is performed horizontally or vertically. 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. STF series (1200-1300) are tube furnaces, suitable for heat treatment processes which are performed under controlled atmospheric conditions. Wire heating elements located around the hot-zone enables the easy replacement of the tube. Operator can utilize any type of tube/reactor and easily change as required STF series enable the user to heat up to 1300˚C as well as operate the furnace with multiple zones of different lengths
