Heating Mantle

1. Heating Characteristics: Heating is achieved by an electric heating mantle, featuring a large and uniform heated area, rapid temperature increase, with a maximum attainable temperature of 380°C. It can heat and stir both standard and non-standard reaction flasks.
2. Temperature Control System: It is equipped with a dual-screen digital display, possessing self-tuning functionality, high measurement precision, and low temperature overshoot. The operation is facilitated by single-key touch, with temperature measurement conducted by internal and external thermocouples. The output is controlled by a silicon-controlled rectifier and is equipped with protection against thermocouple disconnection.
3. Stirring Function: It employs a DC brushless motor, which offers stable performance, low noise, long service life, and no spark generation. It has stepless speed regulation, providing stable operation at low speeds and powerful performance at high speeds. It also features a digital display of rotational speed, enabling automatic stirring.
4. Inner Liner and Control: Alkali-free glass fiber is used as the insulating material, within which Cr20Ni80 alloy wire springs are placed and vacuum-shaped with aluminosilicate cotton fibers. It demonstrates characteristics such as high temperature resistance and rapid temperature rise. The intelligent temperature control panel ensures more precise readings.
5. Safety Performance: It incorporates an over-temperature protection function. When the temperature exceeds the preset range or the current is excessive, the equipment will automatically cease operation to avoid accidental incidents. It is also equipped with an anti-dry-burning feature.
6. Simple Operation: The panel is concise and clear, and the operation process is straightforward. Users can proficiently master the usage method without the need for complex training, significantly enhancing experimental efficiency.
7. Applicability: It exhibits strong multifunctionality, capable of simultaneously conducting magnetic stirring and electric heating operations, suiting various experimental requirements.

Working Environment Conditions:
1. Ambient Temperature: Generally, it should range between 10°C and 40°C to guarantee the normal operation of the equipment and the accuracy of temperature control.
2. Relative Humidity: The relative humidity of the working environment shall not exceed 85% to avoid excessive moisture causing dampness, electrical leakage or damage to the equipment.
3. Placement Requirements: It should be placed on a horizontal, flat, dry and anti-slip ground. The workbench should be set in a place with less vibration interference.
4. Safety Distance: The equipment should not be placed close to heat sources and must not be used in areas with explosive hazards.
5. Ventilation Conditions: It should be placed in a well-ventilated place and kept away from flammable, explosive items and strong magnetic field equipment.
6. Grounding Requirements: This product must ensure that the equipment is well grounded to prevent electrical leakage accidents. When storing, it should be kept dry and not be exposed to moisture.
7. Power Supply Requirements: Before use, check whether the power supply voltage complies with the equipment requirements and the power cord should be intact.

Precautions:
1. Container Selection: The heating container should be compatible with the electric heating mantle and should not be too large or too small. When using a glass container, direct contact between the container and the inner sleeve of the electric heating mantle should be avoided. Materials such as sea sand can be filled to ensure uniform heating of the container.
2. Heating Operation: Heating should be carried out gradually to prevent container rupture or sample splashing due to sudden temperature increase. During the heating process, close attention should be paid to temperature changes to prevent damage to the sample or equipment due to excessive temperature.
3. Stirring Operation: The electric heating mantle is equipped with a stirring function. Ensure that the stirring bar can rotate freely after being placed in the container and avoid collision with the container wall or bottom. The stirring speed should be appropriately adjusted according to the experimental requirements and the nature of the sample.
4. Cleaning and Maintenance: Dirt and residues on the surface of the electric heating mantle should be promptly cleaned after use to keep the equipment clean. The heating elements and temperature control system of the electric heating mantle should be regularly inspected to ensure their normal operation.
5. Safety Protection: Appropriate protective equipment such as gloves and goggles should be worn during operation to avoid burns from high temperatures and corrosion from chemical reagents. When heating volatile, toxic or corrosive substances, the operation should be conducted in a fume hood and corresponding protective measures should be taken.
