Temperature range and maximum temperature:
Select the appropriate temperature range according to experimental requirements to ensure that the electric furnace can reach the required maximum ashing temperature.
Pay attention to the maximum temperature limit of the electric furnace to avoid exceeding the rated temperature and causing the electric heating element to burn out.

Furnace capacity and sample size:
Select the appropriate furnace space based on the quantity and volume of experimental samples, ensuring that the samples can be evenly placed and fully ashed.

Control method:
It is recommended to choose a digitally controlled electric furnace for convenient temperature and time setting, improving the accuracy and repeatability of experiments.

Security:
Ensure that the electric furnace has necessary safety protection functions, such as over temperature alarm, ground leakage circuit breaker, etc.
The electric furnace should be placed on a stable table, and there should be no flammable or explosive substances around it to ensure the safety of the experimental environment.

Insulation materials and heating elements:
Choose high-quality insulation materials and heating elements to improve the thermal efficiency and service life of the electric furnace.
The insulation material should be able to withstand high temperatures, and the heating element should be able to work stably and have good oxidation resistance.

Convenience of operation:
The operation of the electric furnace should be simple and easy to understand, making it convenient for experimental personnel to set up and adjust.
The controller should be able to accurately display real-time temperature and output power information for easy experimental monitoring.

Daily maintenance and cleaning:
Choose an electric furnace that is easy to maintain and clean, regularly clean the oxide and residue inside the furnace, and keep the furnace clean.
Pay attention to the maintenance and replacement of thermocouples, and avoid pulling them out suddenly at high temperatures to prevent the jacket from exploding.

After sales service and brand reputation:
Choose well-known brands and electric furnaces with good reputation to ensure product quality and after-sales service.
Understand the warranty period and maintenance service policy of electric furnaces, so that problems encountered during use can be resolved in a timely manner.

Special requirements:
If the experiment involves corrosive samples or special ashing conditions, an electric furnace with corresponding protective functions should be selected.
For experiments that require long-term continuous operation, electric furnaces with good durability and stability should be selected.
