# FST/FZS Split Tube Furnaces Up to 1300°C

**The FST, single zone, and FZS, 3-zone, split tube furnaces can be used either vertically or horizontally and have a maximum operating temperature of 1300 °C.** The split heating module allows easy positioning of the work tube or around reactors with fixed-end flanges. The split design may also allow faster cooling of the sample. Cooling channels are engineered into the housing to aid with convection cooling of the outer case. A handle is attached to the upper half of the split tube furnace with two quick-release clamps to unlock and lock the furnace safely. The two furnace halves are ceramic fibre modules with high-quality APM wire heating elements mounted in the insulation, held in position by a ceramic holding ridge. A safety switch protects the operator by switching off the heating elements once the furnace is opened. Customized versions and a comprehensive range of tube furnace accessories are available.
