1. Heat Resistance: It has a low coefficient of thermal expansion and is capable of withstanding heating.
2. Chemical Resistance: It exhibits strong chemical stability and is resistant to the corrosion of multiple chemical reagents, making it suitable for a wide range of experimental environments.
3. Structural Design: The conical shape of the bottle body is conducive to mixing. The narrow mouth is convenient for adding materials and sealing. Capacities are optional and some are equipped with scale marks.
4. Transparency: It is colorless and transparent, facilitating the observation of experimental phenomena.

Working Environment Conditions:
1. Temperature Range: Capable of withstanding from room temperature to approximately 300°C.
2. Chemical Environment: Resistant to the majority of acids, bases, and salts, and suitable for high-purity chemical experiments.
3. Optical Properties: Exhibiting high light transmittance, and suitable for optical observations.
4. Mechanical Properties: Characterized by low density, high hardness, high impact strength, scratch resistance, and suitable for experimental environments that require frequent operations and movements.

Precautions:
1. Uniform Heating: Prior to heating, dry the liquid on the container's surface and place it on an asbestos net to ensure uniform heat distribution. Do not conduct dry heating.
2. Liquid Volume Control: The liquid to be heated within the container should not exceed two-thirds of its capacity.
3. Avoidance of Temperature Shock: Do not place a heated container on a cold and damp countertop or a cold container on a heat source to prevent the container from cracking due to temperature variations.
4. Handling of Corrosive Liquids: When heating corrosive liquids, cover the mouth of the container with a watch glass.
5. Integrity Inspection: Before usage, inspect the conical flask for cracks, notches, scratches, or other defects. The use of corroded or damaged products is prohibited.
6. Sealing: Employ an appropriate stopper (such as a rubber stopper or metal cap) to ensure a tight seal and prevent liquid evaporation and the ingress of external impurities.
7. Storage Conditions: Store in a dry and clean location, avoiding collisions and damages.
8. Cleaning: Promptly clean after usage to prevent residue from adhering to the bottle walls. A soft brush and appropriate detergent can be utilized for cleaning.
9. Disinfection: High-temperature and high-pressure sterilization is feasible, but ensure that the temperature and pressure changes during the sterilization process do not cause damage to the conical flask.
10. Oscillation Operation: During oscillation operations, ensure that the volume of liquid in the bottle is appropriate to prevent spillage.
11. Titration Operation: During the titration process, the straight-mouth design facilitates the insertion and operation of the burette. Ensure a proper fit between the burette and the bottle mouth to prevent liquid spillover.
12. Marking: Make markings on the bottle body to record experimental contents, dates, and other information for convenient experimental management and traceability.
