Introduction: The fully automatic rotary oscillating octal extractor is a liquid-liquid extraction device used in chemical laboratories. At present, in the domestic laboratory, the liquid-liquid chemical extraction is commonly used for shaking extraction or hand-shaking extraction with a separatory funnel. These two methods are cumbersome, low in extraction efficiency, and labor-intensive, and the organic solvent used in extraction will bring physical harm to the experimenter. For this reason, our unit has developed an automatic rotating and oscillating eight-unit extractor. This product is fully automatic and consists of three parts: an extraction bottle, an adjustable frequency motor and a control system. Its working principle is to make the extractant rotate back and forth in the extraction bottle from top to bottom, and then from bottom to top through the adjustable frequency motor, so that the extractant and the water sample are fully combined and violently collided, and the rotation is oscillated to achieve the purpose of complete extraction. At the same time, the whole extraction is completed in a closed extraction bottle, which completely solves the problem of reagent volatilization, makes the extraction result more stable and reliable, and the extraction data is authentic and credible. The fully automatic rotary oscillating octal extractor can be widely used in the extraction of surface water, tap water, industrial waste water and domestic sewage, mainly for petroleum in water bodies. Features: 1. Speed: 0-200 revolutions per minute, digital display adjustable; rotation mode: forward or reverse 2. Closed extraction, fully simulating manual hand shaking, 360-degree rotation, making extraction results more realistic and reliable 3. The extraction efficiency is greater than 95%. Essentially different from ordinary oscillators, making the extraction data more authentic and credible 4. The extraction automation is high and the extraction speed is fast. Extract multiple samples simultaneously in 2 minutes 5. Extraction time: full digital timing, seconds, minutes, hours optional 1s-99h99m 6. Compliant with HJ 637-2012 (replacing GB/T16488-1996) standard, it can rotate at a speed of 180-200rpm, and the oscillation frequency can reach 300 times during the rotation 7. It is equipped with a sanitary stainless steel cleaning tank with its own liquid discharge valve, which is convenient for waste liquid discharge and extraction bottle cleaning 8. The flip-top design can quickly pick and place the extraction bottle, which is convenient and fast 9. The number of samples that can be extracted at one time is large, and the instrument is small in size, and can be placed in a fume hood according to standard regulations Technical parameter: Model:UPQ-XZD08 Sampling volume: 1000ml Number of samples: 8 Remarks: It is used for the extraction of petroleum, anions, volatile phenols, etc. in industrial wastewater and domestic sewage.
