Split tube furnace up to 1300°C - FST/FZS



The split tube furnace type FST/FZS can be operated in both vertical and horizontal orientations up to 1300 °C

The split tube arrangement of the heating module allows for an easy positioning of the work tube or even whole reactors with multiple adapters. The opening mechanism of the furnace allows faster cooling of the sample as well. The insulation consists of light, multi-layer fibre material.

The split rectangular housing with slots for convection cooling provides a cool outer case at any point of time. A bracket handle is attached to the upper half of the split tube furnace with two quick-action clamps to safely lock the furnace. The two furnace halves are made of vacuum formed fibre modules with heating elements mounted to the insulation by a ceramic holding ridge. A safety door switch protects personnel by switching off the heating elements immediately upon opening the door.

This split tube furnace is available as a single-zone version (FST) as well as a three-zone version (FZS) for comprehensive temperature control.

Customized versions and a comprehensive range of tube furnace accessories complete the available options.
