The Carbolite Gero CTF 12/75/700 is a high-performance, single-zone horizontal tube furnace precision-engineered to deliver reliable and cost-effective thermal processing for advanced laboratory research, materials science, and industrial testing. Reaching a maximum temperature of 1200 °C, this model features a robust wire-wound heating element wrapped directly onto a fixed, integrated ceramic work tube. This streamlined, self-contained configuration eliminates the necessity of purchasing an independent work tube for standard open-air heating cycles, delivering an exceptional balance between operational efficiency and infrastructure economy.
The furnace body is conveniently mounted horizontally directly above its integrated control module to minimize the device's laboratory benchtop footprint. Thermal management is driven by the industry-standard Carbolite Gero 301 digital PID controller, which offers single-ramp heating to setpoint, an integrated process timer, and a delayed start function as standard. Offering a dependable 1100 °C continuous operating temperature and an extended uniform zone, the CTF 12/75/700 is an invaluable asset for academic research and advanced quality control applications.
Integrated Ceramic Tube Construction: Heating elements are wound directly onto the structural internal ceramic tube, eliminating initial secondary accessory setup costs.
Atmospheric Adaptability: For applications requiring high vacuum or modified gas atmospheres, a separate, extended inner work tube can be smoothly inserted to accommodate gas-tight end seals and flanges.
Core Heating Element Protection: Utilizing an optional secondary inner work tube effectively shields the primary ceramic assembly and heating coils from aggressive outgassing and sample cross-contamination.
Precision PID Regulation: Outfitted with the 301 digital controller as standard, providing rock-solid temperature stability and intuitive digital process timing.
Extended Thermal Uniformity: The 900 mm heated length yields a generous 455 mm uniform temperature zone ($\pm5$ °C) for highly accurate and stable sample profiling.
Space-Saving Benchtop Layout: The horizontal furnace chamber is stacked vertically above the control enclosure for a rigid, secure, and compact industrial footprint.
