1. Structural Design: The main body is conical, spherical or cylindrical, and the Stopcock is connected by ground joint, facilitating liquid stratification and controlling the outflow.
2. Material Properties: The highly transparent glass is chemically resistant and suitable for a wide range of chemical environments. It possesses a certain degree of heat resistance; however, sudden cooling and heating should be avoided.
3. Operational Performance: The liquid outflow can be precisely controlled. It is easy for layering observation and cleaning, thereby improving the efficiency and accuracy of experiments.
4. Extensive Applications: It is utilized for the separation of immiscible liquids, such as organic solvents and aqueous phases, and is applicable in fields like organic chemistry and analytical chemistry.

Working Environment Conditions:
1. Temperature: Utilized at ambient temperature (15 - 30℃), with extreme temperatures to be avoided.
2. Pressure: Applicable in an ambient pressure environment, and pressure shock should be evaded.
3. Humidity: Employed and stored in a dry setting, with excessive humidity to be prevented.
4. Chemical Environment: Resistant to the corrosion of multiple chemical reagents, yet prolonged contact with strongly corrosive substances is necessary to be avoided.
5. Mechanical Conditions: Placed stably, handled delicately, and collision and vibration should be precluded.
6. Illumination: Direct intense light should be evaded, and shading is necessary when required.
7. Vibration: Vibration should be mitigated to ensure the liquid stratification effect.
Precautions:
1. Seal inspection: Ensure a good seal of the Stopcock or Glass Stopper before use to prevent liquid leakage.
2. Appropriate filling: The volume of the liquid poured should not exceed two-thirds of the funnel's capacity to avoid overflow and interference with stratification.
3. Gentle handling: Due to the fragility of glass, handle the funnel delicately to prevent collision and dropping.
4. Timely cleaning: Clean promptly after use to maintain cleanliness. Regularly inspect the flexibility and sealing performance of the Stopcock or Glass Stopper.
5. Avoid cross-contamination: When dealing with different liquids, use dedicated funnels or conduct thorough cleaning to prevent cross-contamination.
5. Protective measures: When operating with toxic or corrosive liquids, wear protective gloves, goggles, etc.
6. Standing for stratification: When separating liquids, allow sufficient standing time for complete stratification of the liquids.
7. Slow liquid discharge: When releasing the liquid, rotate the stopcock slowly to control the flow rate and prevent the carry-over of the upper layer liquid.
8. Proper storage: When not in use for an extended period, store the funnel in a dry, well-ventilated, and shady area, avoiding direct sunlight and humidity.
9. Avoid extreme conditions: Do not use the funnel in extreme temperatures, pressures, or chemical environments to prevent damage.
