Description
The Mellen Microtherm MTSC12.5R model with a 1.25″ bore delivers reliable, high-temperature performance up to 1,250 °C in air, suited for lab work, annealing, and controlled temperature processing. Its clamshell housing ensures quick sample or tube changes, improving workflow efficiency and safety.
Supported by Vulcan-style APM heating elements, the design ensures stable, no-sag performance during use. Encapsulated within ceramic-fiber insulation, the furnace achieves fast heat-up and consistent temperature control. Compatible with horizontal or vertical configurations, this model connects to external PID controllers (sold separately) for precise temperature regulation.
