Shanghai Naiai Instrument is an instrument enterprise focused on experimental instrument design, research and development, production, and sales. Currently, we sell and produce integrated distillation instruments, traditional Chinese medicine sulfur dioxide distillation instruments, COD digestion instruments, high chlorine COD digestion instruments, sulfide acidification blowing instruments, fully automatic liquid-liquid extraction instruments, volatile oil determination instruments, and more.

The intelligent liquid-liquid extraction instrument is mainly used to replace hand cranked extraction in liquid-liquid extraction and optimize the liquid-liquid extraction process. This instrument replaces manual shaking and adopts a semi enclosed air flow internal circulation oscillation. Its principle is to use air pressure to fully combine water samples and extractants and collide vigorously to achieve the purpose of extraction, reducing unnecessary labor for experimental personnel, protecting the health of operators, improving extraction efficiency, and making analysis results more stable and reliable. Suitable for situations requiring liquid-liquid extraction such as petroleum in water quality monitoring, and can also be used for automatic liquid-liquid extraction of volatile phenols and anionic surfactants in water.

Main features

1. The instrument body adopts a frame integrated design, which is stable and reliable. The main body is made of branded cold-rolled plate with electrostatic powder coating, which is more wear-resistant and corrosion-resistant;
2. From air to contacts, relay protectors to button switches, etc., use Chint/Delixi or equivalent electrical brands to ensure instrument quality and service life;
3Adopting a PLC control system with stable and powerful performance, the 7-inch touch screen can achieve full process control such as automatic extraction, automatic exhaust, automatic cleaning, and automatic waste discharge;
4. It can extract 1 to 4 samples at once, and the sample bottles are four sets of three port separating funnel extraction bottles with polytetrafluoroethylene valves, with standard 500ml or 1000ml capacity;
5. Each extraction bottle has an independent glass air duct inserted into the bottom of the extraction bottle (which can be replaced with a PTFE blowing plug and PTFE air duct according to customer needs);
6. Adopting the semi enclosed airflow oscillation principle and continuously inflating with an internal air pump to achieve oscillatory extraction, the extraction intensity can be adjusted from weak to strong;
7. During the reaction process, exhaust gas is generated, which is automatically and uniformly discharged and treated without the need for manual venting, while avoiding the risk of bursting of fully enclosed extraction bottles;
☆8. Each extraction bottle is equipped with a specially designed glass spray cleaning plug, which uses a constant pressure scattering wide-angle cleaning technology to fully cover the inner wall of the separation funnel. The dual channel automatic suction of detergent or pure water enables automatic rinsing of the extraction bottle;
☆9. The cleaned waste liquid is discharged into the waste water tank inside the host through an independent push-pull waste liquid collection tank, which is made of POM material resistant to organic solvent corrosion;
10. The waste liquid tank is equipped with a liquid level device, which automatically starts the waste liquid discharge program after reaching the preset water level. After filtering some toxic and harmful substances through activated carbon, the waste is uniformly discharged;
11. The system comes with an instruction manual and a QR code for the service center. Scanning the code with your phone will automatically view the electronic instruction manual and connect to the service center with just one click.
