1、 Execution standards

The KD-1000 automatic liquid-liquid extractor operates in a fully automatic mode and consists of an extraction bottle, gas-liquid pump, and control unit. Its working principle is to use air pressure to fully combine the water sample and extractant and collide vigorously to achieve complete extraction. It completely replaces manual shaking, reduces the labor intensity of experimental personnel, avoids direct contact between humans and toxic reagents, protects the health of operators, and the entire extraction process does not require manual gas release, but can automatically drain and clean At the same time, the automatic liquid-liquid extraction device greatly reduces environmental pollution, improves extraction efficiency, and ensures stable and reliable analysis results. Can be widely used for liquid-liquid extraction of oil, volatile phenols, anions, and other substances in water bodies.

2、 Performance characteristics

★ (1) A liquid-liquid extractor that can automatically extract, clean, and discharge waste;

(2) During the entire extraction and cleaning process, the experimental personnel had no contact with harmful volatile solvents, ensuring their physical and mental health;

(3) Waste liquid can be collected manually or automatically discharged, suitable for extraction experiments of different samples;

(4) Large screen touch screen operation, user-friendly and convenient interface, easy for experimental personnel to operate;

★ (5) Adopting the semi enclosed airflow oscillation principle, automatic gas release can be achieved without manual release. Toxic gases can be collected and processed through activated carbon devices and automatically discharged, making the experimental environment safer. At the same time, it avoids the risk of extraction bottle bursting caused by fully enclosed design;

★ (6) Unlike other instruments with simple flushing function, this instrument adopts a constant pressure scattering wide-angle cleaning, covering the entire inner wall of the separating funnel, and the cleaning effect is more reliable;

(7) One click extraction oscillation, automatic static stratification, each sample can be individually controlled;

★ (8) Dual channel automatic suction of detergent and cleaning pure water, achieving automatic washing and rinsing;

(9) The waste liquid is automatically discharged, and activated carbon storage tanks can be used for automatic filtration and adsorption treatment;

(10) One to six samples can be extracted at once, with high extraction efficiency and simple and convenient operation;

★ (11) Intelligent microcomputer operation, using a 7-inch color touch screen, the display screen is fixed in front of the machine for easy operation by laboratory personnel, and various instrument parameters can be set independently;

(12) Extraction and cleaning can both be timed and operated at set times;

(13) One machine is versatile and can be used for liquid-liquid extraction of oil, volatile phenols, anions, and other substances in water bodies; The sample bottle can hold 6 1000ml separating funnels or 500ml separating funnels.

(14) The use of 24V safe voltage supply ensures absolute safety for experimental personnel under extreme conditions.
