Hash COD reagent 2125815-cn

Hash reagents can use reagent blank correction and standard adjustment functions to correct system differences in test results. The large screen COD measurement results can be displayed, and COD concentration, absorbance, or transmittance values can be displayed as needed

Features:
The prepared reagents are packaged in colorimetric bottles or sealed bags for one experiment.
Small processing capacity and * short preparation time.
Reduce errors in manually preparing reagents to provide results with high accuracy and good reproducibility.
Reduce and avoid the use of hazardous chemical reagents, such as nitrate determination without cadmium, ammonia nitrogen determination without mercury, etc.
Processing the reacted sample in a capped reagent bottle is simpler and more feasible.
Reduce the waste liquid generated in the laboratory and the resulting waste liquid treatment costs.

Accessory, or 4 AA alkaline batteries

The laboratory should only store a small amount of drugs that need to be used in the short term. Flammable and explosive reagents should be placed in iron cabinets, and there should be ventilation openings at the top of the cabinets It is strictly prohibited to store a total of 20L bottled flammable liquids in the laboratory. A large amount of reagents should be stored in the reagent warehouse. For general reagents, such as elemental salts, they should be stored in an orderly manner in the reagent cabinet, and can be stored according to the periodic group of elements, or classified according to acids, bases, salts, oxides, etc. When storing reagents, attention should be paid to the storage period of chemical reagents. Some reagents may gradually deteriorate and even form hazardous substances during storage. Such as ethers, tetrahydrofuran, dioxane, alkenes, liquid paraffin, etc., under visible light conditions, can form peroxides if exposed to air, and the longer they are stored, the more dangerous they become. Some reducing reagents, such as triphenylphenol, titanium trichloride, sodium tetrahydroborate, as well as metal wires, aluminum, magnesium, zinc powder, etc., are easily oxidized and deteriorated by oxygen in the air.
