1. The entire machine is constructed using high-quality 304 stainless steel, aluminum alloy, and novel synthetic materials. These materials endow the machine with excellent corrosion and rust resistance properties, enabling it to endure various solvents.
2. All glass components are fabricated from high borosilicate glass. This glass is suitable for use with all media, excluding hydrofluoric acid, hot phosphoric acid, and high-temperature concentrated alkalis.
3. The variable-frequency speed-regulating motor features a brushless design, eliminating sparks and reducing noise levels. With a pure copper core, it can achieve high rotational speeds. The enlarged turbine contributes to the motor's safety, stability, and extended service life.
4. PTFE and specialty rubber composite seals ensure chemical resistance against a wide range of solvents while maintaining high vacuum integrity. Easy to install and replace.
5. The vertical high-efficiency condenser is designed to achieve a high recovery rate.
6. The machine is equipped with universal wheels with foot brakes, facilitating easy movement.

Precautions:
1. Conduct a meticulous inspection of the inner and outer walls of the glass reaction kettle for cracks, bubbles, or damage, with particular attention to the integrity of the glass layer. Verify the proper fit of all interfaces, ensuring no signs of looseness or leakage.
2. Examine the power cord for signs of aging, damage, or exposure, and ensure a secure connection of the plug. Confirm that the power supply voltage aligns with the equipment requirements, and take precautions to prevent the electrical components from being exposed to moisture.
3. Manually rotate the stirring shaft to ensure smooth rotation without collision with the thermowell. Check that the stirring paddle is vertically and securely fixed, ensuring concentricity.
4. Inspect all interfaces for proper alignment. Wipe each interface with a soft cloth and apply an appropriate amount of vacuum grease to enhance the sealing performance.
5. Ascertain the compatibility of the reactants and solvents with the material of the reaction kettle to avoid corrosion.
6. Ensure that the volume of the material does not exceed two-thirds of the kettle's volume for liquid substances or one-half for solid substances or reactions that generate gas, leaving sufficient space for expansion.
7. Tighten the bolts evenly and symmetrically to ensure that the sealing ring lies flat without distortion.  Gradually increase pressure and temperature to avoid sudden changes that may compromise sealing integrity. Never exceed 80% of the vessel's design pressure.
8. Refrain from running the equipment at high speeds under no-load conditions to prevent damage to the motor.
9. Avoid over-tightening PTFE switches (such as the discharge valve) to prevent damage to the glass components. After shutdown, loosen all PTFE switches to prevent piston deformation due to prolonged static conditions.
10. During operation, if it is necessary to close the jacket circulation ports simultaneously, install and open a pressure relief valve between the valve and the circulation port to prevent pressure build-up and potential rupture of the jacket.
11. After each use, select an appropriate solvent based on the nature of the residues for cleaning. Gently wipe the surfaces with a soft cloth or sponge to avoid scratching the glass. After cleaning, ensure thorough drying of the interior and exterior of the reaction kettle to prevent water accumulation over time.
