Fully Automatic Liquid-Liquid Extraction Apparatus CHZDCQ-6 Water-Oil Extraction UnitKey Features:

1. 7-inch large LCD touch screen, one-touch operation system, the display is fixed in front of the machine for easy operation by lab personnel, allowing for self-setting of various instrument parameters.

2. Supports extraction bottles in various specifications, with a snap-on design for easy and simple replacement; all gas valves are made of PTFE material.

3. 6-position operating system, capable of extracting 6 samples simultaneously, with an automatic extraction program running, automatic settling and stratification, and individual control for each sample.

4. Extraction time, cleaning time, intermittent time, and extraction cycle can all be set and adjusted. An alarm function is accompanied by the completion of extraction and cleaning.

5. Auto-waste liquid discharge with a stainless steel telescopic waste liquid tank, featuring built-in waste liquid activated carbon filtration and purification function. After being filtered and adsorbed by the activated carbon storage tank, the waste liquid is collected and treated centrally, reducing environmental pollution. Suitable for the use requirements of various reagents, comes with a vacuum filtration system, manual waste liquid discharge.

6. Waste gases are produced during the reaction process, which are automatically discharged and treated uniformly. Manual venting is also available, while avoiding the risk of explosion associated with fully enclosed extraction bottles.

7. Utilizing a fixed-pressure scatter-wide-angle cleaning method, it covers the entire inner wall of the separatory funnel with a single-button automatic cleaning, achieving a cleaning effect of;

8. The unit features electrical leakage protection, overvoltage and overcurrent protection devices, and is equipped with 6 built-in stable voltage systems to enhance the consistency of the machine's extraction efficiency.

9. The extraction strength is adjustable via a knob, and each group can be individually set to adjust.

10. Utilizes an automatic metering pump for sample feeding and manual addition, eliminating direct contact with toxic reagents, safeguarding staff health, and ensuring quick and convenient operation.

11. Employing a semi-enclosed air flow oscillation principle, the system achieves oscillation extraction through a continuous aeration method powered by an internal air pump. Extraction intensity can be adjusted from weak to strong.

The automatic liquid-liquid extraction instrument is a common pretreatment operation in laboratories at all levels. Manual extraction is labor-intensive, inefficient, and poses a significant risk of inhaling toxic gases. The commonly available automatic liquid-liquid extraction units are mainly reciprocating oscillating, 360-degree flipping, stirring, and jet types, each with its own drawbacks. The first two require manual venting, which only saves on the oscillation process, while the latter two are prone to solvent evaporation and are difficult to clean. The automatic liquid-liquid extraction instrument draws on the strengths of similar products while avoiding their shortcomings, creatively using a closed-gas flow oscillation internal circulation principle. It can be started with a single button, automatically extracts, vents during extraction, automatically cleans after extraction, and the waste liquid is adsorbed by an activated carbon adsorption tank before being automatically discharged. All operational instructions and parameters can be controlled through a liquid crystal touch screen. It boasts high automation, time and labor savings, energy conservation, and environmental protection. It is suitable for various applications requiring liquid-liquid extraction in water quality monitoring, such as water oil, volatiles, and other scenarios.

Fully Automatic Liquid-Liquid Extraction Instrument CHZDCQ-6 Water-Oil Extraction UnitThe principle of the fully automatic liquid-liquid extraction instrument is to utilize air pressure to thoroughly mix and vigorously collide the water sample with the extraction agent, achieving the extraction purpose. It replaces manual shaking, reduces the labor intensity of laboratory personnel, avoids direct contact with toxic reagents, and protects the health of the operators. The entire extraction process does not require manual venting; it can automatically drain and clean the liquid-liquid extraction instrument. Additionally, the automatic liquid-liquid extraction device significantly reduces environmental pollution, improves extraction efficiency, and ensures stable analysis results. It is widely applicable to all liquid-liquid extraction tasks, including oils, volatiles, anions, and more, in water bodies.
