The Carbolite Gero CWF-BAL 11/21 is a high-performance, bench-mounted laboratory chamber furnace integrated with a precision weighing balance system specifically engineered for thermogravimetric analysis (TGA) and Loss on Ignition (LOI) applications. Providing a well-proportioned chamber volume of 21 litres and a maximum operating temperature of 1100 °C, this analytical furnace is ideal for determining the inorganic substance content in materials such as cement, lime, calcined bauxite, and refractories. The integrated balance works independently of the heating control layout, delivering real-time, continuous monitoring of sample mass variation throughout the entire thermal processing cycle.
Thermal regulation is managed by an advanced Eurotherm 3216CC digital PID controller, which supplies a precise single-ramp profile to setpoint and integrated process timing. Mass loss telemetry captured by the balance can be easily tracked and graphed via a connected computer utilizing the supplied software package. To ensure rigorous workplace ergonomics and safe everyday laboratory operation, the furnace incorporates a vertical lift door configuration that directs radiant heat away from the technician. Built with free-radiating wire-wound elements and tough alumina ceramic interiors, the CWF-BAL 11/21 guarantees high thermal performance and structural resistance against heavy material loading.
Integral Weighing Balance: Built-in balance mechanism operating independently from the heating array, offering a standard capacity of 3 kg with a high-resolution readout of 0.01 g.
TGA Data Logging Software: Includes specialized software to continuously track, chart, and export sample weight variations and mass drop metrics over time via PC interface.
Vertical Lift Door with Soft-Close: Upward-opening door system isolates the operator from the white-hot inner insulation face, paired with a mechanical dampening system for smooth closing.
Heavy-Wearing Alumina Liners: Structural alumina element carriers, furnace entrance, and base hearth stand up to repeated friction from crucible loading and avoid sample cross-contamination.
Advanced 3216CC Controller: Fitted with the industrial Eurotherm 3216CC digital controller as standard, supporting automated process timing and single-ramp profiles.
Free-Radiating Wire-Wound Elements: Exposed element arrays offer excellent radiant heat distribution, linear thermal tracking, and fast thermal response times.
