Microwave ashing ovenBy directly applying microwave energy to sample molecules, high-frequency vibrations are generated through molecular polarization, converting electromagnetic energy into thermal energy and achieving rapid temperature rise inside the sample. Its heating method is completely different from the external heat conduction of traditional muffle furnaces.

Technical advantages:

1. Penetrating heating: Microwaves can penetrate the sample, causing synchronous heating of the interior and surface, avoiding the "from outside to inside" thermal hysteresis problem of traditional heating.

2. High frequency vibration generates heat: molecules vibrate billions of times per second and generate heat through friction, with much higher efficiency than traditional thermal radiation.

3. Airflow co oxidation: By designing a downward pressure airflow, high concentration oxygen is introduced to accelerate the oxidation and decomposition of organic matter, reducing the ashing time from "hour level" to "minute level".
