Carbolite FST & FZS Split Tube Furnaces

Carbolite Gero FST, FZS Horizontal and Vertical Split Tube Furnaces, maximum temperature 1300°C

FST a single-zone furnace range, and the FZS are three-zone models. Both can be used either vertically or horizontally. The split heating module allows either easy positioning of the work tube or positioning around reactors which have 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.
