1. Heat Resistance: It boasts a low coefficient of thermal expansion, can endure substantial temperature variations, and can be directly heated by open flame without a propensity for cracking.
2. Chemical Stability: It exhibits strong corrosion resistance and is not prone to reactions with chemical reagents, making it suitable for containing and handling multiple chemical samples.
3. Mechanical Properties: It possesses high hardness, excellent abrasion resistance, and an extended service life.
4. Round Bottom Design: Heat is evenly distributed, facilitating liquid mixing and stirring and minimizing splashing.
5. Ground Joint Design: It features superior sealing performance and can closely cooperate with ground stoppers and the like to prevent leakage, being suitable for sealed operations.

Working Environment Conditions:
1. Temperature: The temperature range is from 0 to 300°C. It can withstand considerable temperature variations and can be directly subjected to open flame heating. Nevertheless, when heating, a terra cotta net or the like should be placed beneath to ensure uniform heat distribution and prevent local overheating.
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: Add zeolite for distillation, 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.
