Supply of AE-03 Automatic Extractor Introduction:
Technical Principle: For the determination of petroleum and animal/vegetable oils using the infrared spectrophotometry method, water samples need to be extracted. The separatory funnel is placed on the automatic extractor stand, and both the water sample and extraction solvent are poured into the funnel. Since the extraction solvent has a higher specific gravity than water, it settles at the bottom of the funnel due to gravity. However, when the air pump blows air into the bottom of the funnel, the extraction solvent churns upward and rapidly mixes thoroughly with the water sample above. The air volume of the pump can be adjusted, and the total extraction time can be controlled by a time relay, allowing the extraction solvent to fully extract oil substances from the water.

Supply of AE-03 Automatic Extractor Main Features:
Comparison with Traditional Extraction Methods

Criteria: Automatic Extractor / Manual Extraction with Separatory Funnel

Safety:
Automatic Extractor: Operators do not directly contact carbon tetrachloride, ensuring high safety.
Manual Extraction with Separatory Funnel: Operators need to open the stopcock of the separatory funnel to release gas during the process, leading to direct contact with carbon tetrachloride and poor safety.

Extraction Efficiency
Automatic Extractor: The air volume of the pump can be adjusted, allowing thorough contact between the extraction solvent and water sample, resulting in high extraction efficiency.
Manual Extraction with Separatory Funnel: Relatively lower extraction efficiency.

Repeatability
Automatic Extractor: Once conditions are set, no manual intervention is needed; purely mechanical operation ensures good repeatability.
Manual Extraction with Separatory Funnel: High human influence, unstable conditions, and poor repeatability.

Labor Intensity
Automatic Extractor: Fully automated operation with the capability to extract multiple samples simultaneously, resulting in low labor intensity.
Manual Extraction with Separatory Funnel: High labor intensity when dealing with large water sample volumes or numerous samples.
