chemical composition Root contains 3,4-dihydroxyacetophenone, hydroquinone, scopoletin, esculetin, homovanillic acid ) And glaberide I. The triterpenoids were separated from the roots: ilexisaponin A1, ilexgenin A, holloside B1, B2, B3, ilexolide A, and holly three Ilexoside) A, D, E, J, K, O, pubescenic acid. Brand computer chips, dual-frequency integrated circuits, cross-magnetic induction detection, bringing higher accuracy, reliability and stability. 2. Automatic control system, using special magnetic materials and unique technology, the detection accuracy of the probe is particularly high, and the accurate position of the broken needle is displayed in 8 detection areas. 3. Dual probe design, double detection function, higher safety performance, compared with other types of needle detectors, at the same detection height, the sensitivity is increased by 10%. 4. Automatic detection, automatic induction, automatic stop when no detection is needed, 0-10 sensitivity adjustment, when there is a broken needle, the conveyor belt automatically stops and returns backwards. 5. With a counting function, it can count the number of qualified or unqualified products. 6. It has two alarm modes: sound effect and light alarm. 7. Luxurious appearance, novel style, time-saving and power-saving, simple operation Rapid PCR detection,Rapid Detection Rapid Detection PCR Kit Viral Antigen Detection Jiangsu iiLO Biotechnology Co., Ltd. , https://www.sjiilobiotech.com
