The Carbolite Gero CWF 12/5 is a high-precision, bench-mounted laboratory chamber furnace engineered for general-purpose thermal processing, micro-sample synthesis, materials testing, and industrial ashing routines. Providing a compact and space-saving chamber volume of 5 litres and a maximum operating temperature of 1200 °C, this muffle furnace is the ideal configuration for advanced academic research or laboratories treating smaller batch sizes under precise heat profiles. The heating architecture integrates free-radiating wire-wound elements with energy-efficient, low thermal mass insulation to guarantee deep thermal saturation, exceptional thermal response, and optimized temperature uniformity.
Operational safety and structural durability are foundational to the CWF 12/5 design. It features an ergonomic vertical lift door mechanism that safely positions the white-hot radiant inner insulation face away from the operator during loading and unloading tasks, directing the residual heat upward. To prevent mechanical degradation, friction, and thermal shock from recurring sample handling, the furnace entrance, structural hearth, and element carriers are manufactured from premium-grade hard-wearing alumina ceramics. Thermal management is governed by the reliable Carbolite Gero 301 digital PID controller, offering precise single-ramp control, an automated delayed start, and integrated digital process timing.
Compact and High-Performance Design: The 5-litre internal chamber combined with a 1200 °C thermal limit offers a compact yet powerful solution for precise material profiling and heat treatment.
Vertical Lift Door with Soft-Close: Upward-opening door system acts as a shield to protect the technician from direct radiant heat, enhanced by a built-in smooth soft-close dampening mechanism.
Heavy-Wearing Alumina Ceramics: Tough alumina element carriers, furnace entrance, and structural base hearth resist mechanical friction and chemical cross-contamination.
Energy-Efficient Thermal Shielding: High-grade low thermal mass insulation ensures quick recovery and heat-up rates (reaching max temperature in 51 minutes) while maintaining low outer casing temperatures.
Intuitive Digital Automation: Outfitted with the Carbolite Gero 301 PID controller as standard, supporting single-ramp heating profiles, digital process timing, and automated delayed start functions.
Service-Friendly Layout: Direct access to internal electronic components and heating configurations simplifies routine technical service, maintenance, and calibration processes.
