General Chapters: 281 RESIDUE ON IGNITION

A muffle furnace may be used, if desired, and its use is recommended for the final ignition at 600 50. Calibration of the muffle furnace may be carried out using an appropriate digital temperature meter and a working thermocouple probe calibrated against a standard thermocouple traceable to the National Institute of Standards and Technology.

Ashing Furnaces up to 1100 C Nabertherm

Ashing furnace LV ../11 is designed especially for ashing processes to 1050 C in the laboratory. Applications include determining loss on ignition, ashing food and plastics for subsequent substance analysis. A special fresh-air and exhaust air system ensures that the air is replaced 6 times per minute so that there is always sufficient oxygen for the ashing process.

The Muffle furnace is VERY hot. For safety, you must use asbestos gloves any time the temperature in the furnace exceeds 100C. If samples are rich in organics, it is possible that when they burn up, some ash may float between samples and cause cross-contamination. To minimize this, use big sample containers and burn fewer samples at a time.
