The CWF laboratory furnaces are a versatile range of chamber furnaces that can be easily mounted on a bench. They come in five different sizes and can reach a maximum temperature of 1300°C.
The CWF-B furnaces are designed to improve airflow by adding air inlet holes in the door and a tall chimney that quickly removes fumes from the furnace.
If you need to monitor sample weight changes during the heating process, the CWF-BAL furnace with an integral balance is the best choice. This furnace is ideal for thermogravimetric analysis (TGA) and loss on ignition (LOI) applications. It is particularly useful in determining the inorganic matter content in materials such as cement, lime, calcinated bauxite, and refractories.
For applications involving organic matter content, the AAF-BAL is the recommended furnace.

TECHNICAL DETAILS
Airflow in CWF-B
- Air inlets through the door plug
- Airflow through the chamber promotes the burning of the samples
- The chimney pulls air through the chamber
