The CM 1000 Series Tube Furnaces deliver precise and repeatable temperature control up to 1,200 °C (2,192 °F) for demanding laboratory environments. With half‑round ceramic heating elements mounted on either side of the chamber, and lightweight fiber insulation, these furnaces offer excellent thermal uniformity in a robust yet compact form.
Designed for modular versatility, the 1000 Series supports single or multi-zone configurations, tube diameters of 3″ to 8″, and heated lengths between 12″ and 48″. Standard construction includes a rugged hinged steel shell, unheated vestibules, and mounting brackets that accommodate both horizontal and vertical orientations.
Common applications include material diffusion, annealing wire/strips, sample conditioning, catalyst activation, and inert/vacuum atmosphere processes. These furnaces are built to last—some units remain operational after decades in high-use environments—and are easily maintained thanks to accessible parts and programmable controls.
