The Carbolite Gero CWF 13/23 is a high-performance, bench-mounted laboratory chamber furnace precision-engineered for high-temperature thermal processing, advanced material synthesis, ceramic co-firing, and industrial ashing routines. Providing an optimal chamber volume of 23 litres and an elevated maximum operating temperature of 1300 °C, this muffle furnace perfectly bridges the gap between compact laboratory footprints and elite thermal power. The heating architecture integrates free-radiating wire-wound elements paired with energy-efficient, low thermal mass insulation to guarantee deep thermal saturation, exceptional thermal response, and optimized temperature uniformity, reaching maximum temperature in just 55 minutes.
Operational safety and comprehensive workplace ergonomics are fundamental to the CWF 13/23 design. It features a robust vertical lift door mechanism that safely positions the white-hot radiant inner insulation face away from the technician during sample loading and extraction, directing the residual heat upward. In this 23-litre model, a smooth mechanical soft-close dampening system is integrated as standard to eliminate structural vibration and jar during door closure. To protect the structural core from intense mechanical wear, friction, and thermal shock, the furnace entrance, heavy-duty base hearth, and element carriers are manufactured from premium-grade hard-wearing alumina ceramics. Thermal cycles are precisely governed by the digital Carbolite Gero 301 PID controller, supporting smooth single-ramp control, automated delayed start, and integrated process timing.
Elite Temp & Optimal Volume Combination: The 23-litre internal chamber combined with an elite 1300 °C thermal limit offers a robust, high-performance solution for precise advanced material profiling, technical ceramics, and medium-batch sintering.
Vertical Lift Door with Soft-Close: Upward-opening door architecture acts as a structural shield to protect the user from direct radiant heat exposure, enhanced by an integrated soft-close dampening mechanism.
Heavy-Wearing Alumina Ceramics: Tough alumina element carriers, furnace entrance, and structural base hearth resist mechanical friction from crucible loading and avoid sample cross-contamination.
Energy-Efficient Thermal Shielding: High-grade low thermal mass insulation ensures excellent temperature retention and cycle stability while maintaining low outer casing temperatures for workplace safety.
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, component replacement, and calibration processes.
