The Carbolite Gero CWF 11/5 is a high-precision, bench-mounted laboratory chamber furnace engineered for general-purpose thermal processing, micro-sample ashing, calcination, and materials testing. Providing a compact and space-saving chamber volume of 5 litres and a maximum operating temperature of 1100 °C, this muffle furnace is the ideal choice for laboratories with limited bench space or those processing smaller batch sizes. The heating architecture integrates free-radiating wire-wound elements with energy-efficient, low thermal mass insulation to guarantee excellent thermal response and optimized temperature uniformity.
Operational safety and structural durability are foundational to the CWF 11/5 design. It features an ergonomic vertical lift door mechanism that safely positions the radiant, hot inner insulation surface away from the operator during loading and unloading tasks. To prevent mechanical degradation and abrasion from recurring sample handling, the furnace entrance, structural hearth, and element carriers are manufactured from heavy-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.
Space-Saving Footprint: The 5-litre internal chamber offers an ultra-compact solution for precise thermal workflows without sacrificing industrial build quality.
Vertical Lift Door with Soft-Close: Upward-opening door system shields the technician from direct radiant heat, enhanced by a built-in smooth soft-close mechanism.
Heavy-Wearing Alumina Ceramics: Hard-wearing alumina element carriers, furnace entrance, and base hearth resist mechanical friction and chemical cross-contamination.
Energy-Efficient Thermal Shielding: Low thermal mass insulation ensures quick heat-up rates (reaching max temperature in 47 minutes) and maintains 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 a delayed start function.
Service-Friendly Layout: Direct access to internal electronic components and heating configurations simplifies routine maintenance and calibration processes.
