Fully automatic liquid-liquid extractor with airflow automatic cleaning and air release

working process

The multi link automatic liquid-liquid extractor adopts gas-liquid bidirectional mixing technology, which is used for liquid-liquid extraction pretreatment of oil, volatile phenols, anions and other items in laboratory water quality testing. Widely applicable to laboratories that require extraction and treatment in environmental protection, hygiene and epidemic prevention, water supply and drainage, universities, research institutes, related enterprises, and other fields.

The traditional process of radioactive water sample treatment includes a series of steps such as automatic liquid-liquid extraction instrument sampling, concentration, transfer, washing, burning, ashing, weighing, etc. When concentrating and heating, the sample size should not exceed half of the beaker, and the temperature should not exceed 80 ℃. The operation must be careful and meticulous. The entire water sample pretreatment process is quite long and cumbersome, which brings a lot of inconvenience to the experimenters. The multi link automatic liquid-liquid extraction instrument integrates the far-infrared radiation heating system, intelligent sampling system, and high-precision concentrated automatic liquid-liquid extraction instrument scaling system according to the national standard method. It has functions such as adjustable heat source power, constant temperature heating, modular heat source kit conversion, slow sampling in batches, quantitative control of evaporation and concentration, intelligent voice alarm, etc., realizing various sample evaporation and concentration without personnel duty, intelligent automation, safety and reliability. Suitable for pre-treatment of total alpha beta gamma radioactive indicators in environmental samples such as drinking water, surface water, sewage, and atmospheric deposition in various industries.
Combining traditional methods of automatic liquid-liquid extraction, the shortcomings are eliminated, and a vertical oscillation extraction method is adopted. The extraction process automatically releases gas, and the gas source is collected and processed uniformly through a protective core. One click start, automatic injection, silent oscillation extraction, unified collection of exhaust gas filtered by the filter element and automatically discharged, realizing the intelligence and automation of the entire extraction experiment. The multi link automatic liquid-liquid extraction instrument has a high degree of automation, which not only improves the extraction efficiency, but also effectively avoids the contact between people and toxic and volatile gases, as well as the secondary pollution caused by direct discharge of exhaust gas.
