1. Material: High borosilicate glass, which is characterized by high temperature resistance, strong chemical stability, and high mechanical strength.
2. Structure: The bottleneck is conducive to pouring and connection. The wide and thick mouth facilitates the installation of various accessories. The geometric structure enables uniform heat distribution.
3. Uniform and efficient heating: The spherical flask body design ensures more uniform heating during heating, reduces the generation of local overheating or cold spots, is conducive to the uniform progress of reactions, and enhances the reliability of experimental results.

Working Environment Conditions:
1. Temperature: The normal operating temperature is approximately 230°C, the instantaneous temperature resistance is about 300°C, and the temperature difference resistance is approximately 270°C.
2. Chemical Environment: Resistant to acid and alkali corrosion and has good hydrolysis resistance.
3. Mechanical Environment: Possesses high mechanical strength and high impact strength.
4. Optical Environment: Exhibits good light transmittance, with a light transmittance exceeding 92%.
5. Electrical Environment: Has a large electrical resistivity.

Notes:
1. Heating Mode: Direct flame heating is prohibited. Indirect heating methods such as water bath, oil bath, sand bath or heating jacket should be adopted.
2. Capacity Limitation: When heating, the liquid contained should not exceed 2/3 of the flask's volume and should not be less than 1/3 to prevent liquid boiling over or uneven heating.
3. Handling Method: When holding the flask, hold the outer wall. Fingers should not touch the inner wall to avoid burns or interference with the experiment.
4. Experiment Completion: After the experiment, if there are conduits, etc., remove the conduits first to prevent backflow, then remove the heat source. Wait for the flask to cool down statically before carrying out subsequent processing.
5. Storage Requirements: It is not suitable for long-term storage of chemical reagents. After use, it should be washed, dried and stored upside down immediately.
