Special Price for Kit Pesticide Residue Tester - DRK-880 18-Channel Pesticide Residue Detector – Drick
Special Price for Kit Pesticide Residue Tester - DRK-880 18-Channel Pesticide Residue Detector – Drick Detail:
Channel pesticide residue detector, using enzyme inhibition, referring to national standards, can quickly detect pesticide residues in tested samples, and is widely used in organic phosphorus and carbamate pesticide residues in vegetables, fruits, grain, tea, water and soil The rapid testing is suitable for agricultural testing centers at all levels, production bases, farmer’s markets, supermarkets, hygiene, environmental protection, hotels, restaurants and other fields.
Under certain conditions, organophosphorus and carbamate pesticides can inhibit the normal function of cholinesterase, and the inhibition rate is positively related to the concentration of the pesticide. Under normal circumstances, the enzyme catalyzes the hydrolysis of the nerve conduction metabolite (acetylcholine), and the hydrolyzed product reacts with the color reagent to produce a yellow substance. Use a pesticide residue detector to measure the absorbance change with time to calculate the inhibition rate, which can be judged by the inhibition rate Find out whether the sample contains organophosphorus or carbamate pesticides.
Large screen true color touch screen
