Tubular experimental electric furnace is a commonly used experimental equipment used to heat experimental samples or reagents, mainly used for laboratory research and teaching. The following Zhonghuan electric furnace will introduce the operation steps and precautions of the tubular experimental electric furnace.
1. Operation steps:
Preparation: Place the tubular experimental furnace on a well-ventilated, dry table, making sure there are no flammable materials around. Check whether the power cord of the electric furnace is normal and whether the switch is off.
Sample preparation: According to the needs of the experiment, prepare the experimental samples or reagents to be heated properly to confirm that they do not have any impurities or contamination. Choose the appropriate heating tube or heating chamber according to the experimental requirements.
Mounting the sample: Carefully place the sample or reagent to be heated in the heating area of the heater, ensuring that the distance between the sample and the heating source is reasonable, and keeping the heating area ventilated.
Set the temperature: Set the appropriate temperature according to the experimental requirements and sample characteristics. In general, there is a temperature control knob on the temperature controller, which can adjust the temperature according to the need.
Boot operation: connect the power cord of the electric furnace, turn on the power switch, and the electric furnace starts to work. According to the characteristics of the experimental sample, the heating power is appropriately adjusted to control the heating rate of the sample.
Monitor temperature: During the heating process, the temperature changes of the sample are constantly monitored. Instruments such as thermometers or temperature sensors can be used for real-time monitoring, and the heating power can be adjusted in time to keep the temperature stable.
Heating is complete: When the sample reaches the preset temperature, or at the end of the experiment, the temperature control knob of the electric furnace is adjusted to the minimum and gradually cooled down. After waiting for the furnace to cool completely, carefully remove the sample using a tray or tool.
2. Precautions:
Safe operation: When operating the tubular experimental electric furnace, attention should be paid to safety, avoid touching the heating part and hot surface of the electric furnace, and avoid scalding or electric shock accidents.
Ventilation conditions: When operating the experimental electric furnace, ensure that the ventilation conditions are good to avoid harmful gases or odors. An exhaust system can be set up in the laboratory, or the electric furnace can be placed in a well-ventilated area.
Temperature control: The temperature should be set reasonably to avoid the temperature being too high or too low, which may cause damage to the experimental sample or lose the purpose of the experiment.
Heating area: When operating the tubular experimental electric furnace, the heating area should be kept dry and tidy to avoid debris falling into the heater and causing failure or danger.
Use time: When using the electric furnace for a long time, it is necessary to pay attention to rest in time to avoid excessive fatigue and overheating of the electric furnace, which will affect the experimental effect and safety.
Shutdown operation: After the operation is completed, the temperature control knob should be adjusted to the minimum, the power switch should be cut off, and the electric furnace should be completely cooled before cleaning and maintenance work.
Maintenance: Regularly clean the furnace shell and heating parts, check whether the power cord and switch are normal, and ensure the normal use of the electric furnace.
Through the correct operation steps and precautions, we can safely and efficiently use the tube experimental furnace for experimental research, and provide better conditions and guarantees for scientific research and teaching.
