1. Material Advantage: Utilizing high borosilicate glass, it exhibits a low coefficient of thermal expansion, high-temperature resistance, and strong chemical corrosion resistance, thereby being suitable for diverse experimental environments.
2. Ground Joint Design: The ground joint undergoes meticulous processing, ensuring excellent sealing performance and enabling a snug connection with standard ground joint accessories to prevent the leakage of gas or liquid.
3. Double-joint Structure: The central joint is employed for adding reactants or connecting condensers, while the side port can be utilized for inserting thermometers or other auxiliary devices, presenting diverse functionalities.
4. Strong Durability: It demonstrates superior mechanical shock resistance and a prolonged service life, being suitable for frequent usage.
5. Safe Operation: With favorable sealing performance and heat resistance, it guarantees the safety and accuracy of the experimental process.

Working Environment Conditions:
1. Temperature: The temperature range is from 0 to 300°C. It can withstand considerable temperature variations.
2. Humidity Conditions: It should be stored in a dry environment, with the humidity typically controlled within 45% - 65% RH to avoid the negative impact of moisture on its performance and service life.
3. Chemical Environment: It possesses excellent chemical stability and demonstrates good resistance to acids and alkalis. Nevertheless, prolonged exposure to strong alkalis should be avoided.
4. Mechanical Environment: Handle it delicately to prevent collisions and drops, which might result in cracks, scratches, and other defects.
5. Pressure Conditions: It can generally withstand a pressure of approximately one atmosphere (gauge pressure).

Precautions:
1. Cleaning: Clean promptly using a soft brush and neutral detergent. Avoid hard objects and strongly corrosive cleaning agents.
2. Heating: Place a terra cotta net at the bottom, control the liquid volume within 1/3 - 2/3, and increase the temperature gradually.
3. Assembly: Ensure the ground joints are compatible, insert gently by rotating, and check for airtightness; the installation of accessories should be appropriate, neither too deep nor too shallow.
4. Experiment: Close the stopcock first and then cease heating; closely monitor chemical reactions and handle abnormalities promptly.
5. Storage: Keep it in a dry and well-ventilated area, store it upside down or flat, and store the ground glass stoppers separately.
