How to Extend Service Life of Microwave Furnaces

 

1. When microwave laboratory furnace is used for the first time or is reused after a long period of inactivity, thermal structure and furnace tube must be heated. The heating profile shall be determined by the size of microwave chamber, size and material of tube, etc.The microwave lab furnaces should preferably work 50℃ below the rated temperature.

2. The muffle furnace and controller must work in a place where the relative humidity does not exceed 85%, and there is no conductive dust, explosive gas or corrosive gas. When materials with grease need to be heated, a large amount of volatile gas will affect and corrode/contaminate the surface of the electric components and thermal structure, causing it to be destroyed and shorten the life. Therefore, the pre-heating is very necessary.

 

3, Microwave furnace controller should be limited to use in the ambient temperature range of 0-40 ℃.

 

4. According to the technical requirements, regularly check whether the wiring of the electric furnace and the controller is in good condition, whether the pointer of the indicator is stuck or stagnated when it is moving, and use the potentiometer to calibrate the errors caused by magnetic steel, demagnetization, wire expansion, etc.

 

 5. Do not pull out the thermocouple suddenly at high temperature to prevent the jacket from bursting.

 

6. ​​Always keep the microwave furnace chamber clean and remove oxides in the chamber, tube, crucible in time.
