  • Suitable for detection items: automatic liquid-liquid extraction of volatile phenols, anionic surfactants in water or sample volumes below 500ml.


    The intelligent liquid-liquid extraction instrument that can be operated remotely by a tablet computer can be started with one button, automatic liquid-liquid extraction, the extraction process does not need to be manually vented multiple times, automatic pure water, tap water cleaning waste liquid automatic collection, automatic activated carbon filter discharge

    Product performance standards:
    GB7494-87 "Determination of Anionic Surfactants";
    HJ503-2009 "Water quality-Determination of volatile phenol 4-aminoantipyrine spectrophotometric method"

    product description:
    Liquid-liquid extraction is a very common pre-processing operation in laboratories at all levels. The traditional manual liquid-liquid extraction is labor-intensive, low-efficiency, and operators can easily inhale toxic gases. At present, the common automatic liquid-liquid extraction instruments in the domestic market are mainly vertical oscillation and 360-degree turners, but they partially solve the manual shaking process, and cannot automatically wash and clean, and the efficiency is not high.
    Shengtai STC-302B intelligent automatic liquid-liquid extraction instrument creatively adopts the principle of closed air-flow oscillation internal circulation, the extraction process only needs one button to start, no need to manually vent multiple times; after the extraction, it can automatically pump into pure water or clean, and one button clean , The cleaning waste liquid can be automatically collected or discharged after the toxic gas is automatically filtered.

    Instrument innovation:
    (1) The first liquid-liquid extraction instrument with automatic extraction, automatic cleaning, and automatic waste discharge;
    (2) Creatively adopt the principle of closed air flow internal circulation and oscillation, without manual venting during the extraction process;
    (3) One-key extraction and shaking, automatic standing and layering;
    (4) Automatic inhalation of detergent, automatic washing and cleaning;
    (5) The waste liquid is automatically discharged and automatically filtered and adsorbed by the activated carbon storage tank;
    (6) Six groups of samples can be extracted at one time, with high extraction efficiency and simple and convenient operation;
    (7) Tablet computer remote control operation, one-key setting of operating parameters and automatic operation;
