Description
Code: L.803.xxx.xx
Use
For determining the ash content of paper and pulp samples.
Device description
The high-precision electric muffle furnace is a universal laboratory furnace that fires up to 1100°C and is designed for material tests and heat treatments such as hardening, loosening, normalizing ceramic and earthenware samples and for determining the ash content of pulp and similar products. An extraction system can also be installed in the device to remove gases or smoke released during thermal processing. The oven is ideal for scientific laboratories, educational institutions, ceramics studios, medicine and the pulp and paper industry.
