The Carbolite Gero CWF-B 11/13 is a specialized, bench-mounted laboratory chamber furnace precision-engineered for applications requiring complete sample combustion, controlled ashing, and efficient exhaust gas venting. Providing a balanced chamber volume of 13 litres and a maximum operating temperature of 1100 °C, this model stands out from the standard CWF series through its enhanced airflow system and an extended chimney (CWF-B) architecture. This integrated ventilation profile allows fresh air to enter via dedicated ports in the door plug and circulate through the chamber, actively promoting the complete, rapid, and efficient burn-off of organic and inorganic specimens.
Operational safety and laboratory ergonomics are central to the CWF-B 11/13 design. It features a robust vertical lift door mechanism that safely positions the white-hot radiant inner insulation face away from the technician during loading and sample extraction, directing residual heat upward. In this 13-litre configuration, a mechanical soft-close dampening system is integrated as standard to ensure smooth and vibration-free door closing. To safeguard the structural core from intense mechanical wear, friction, and thermal shock during crucible handling, 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 and integrated process timing.
CWF-B Enhanced Airflow & Tall Chimney: Air inlets integrated into the door plug paired with a rear-mounted chimney draw air directly through the chamber, significantly accelerating complete sample combustion.
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 a smooth soft-close mechanism.
Heavy-Wearing Alumina Ceramics: Hard-wearing alumina element carriers, furnace entry, and bottom hearth resist mechanical abrasion and sample cross-contamination.
Energy-Efficient Thermal Shielding: Advanced low thermal mass insulation ensures fast cycle times (reaching maximum temperature in 60 minutes) while maintaining a low outer casing profile 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 sub-assemblies simplifies routine technical service, component replacement, and calibration protocols.
