COD solid consumables
Classic LH-D/E series dish colorimetry
Features
1. High stability, high accuracy, wide measurement range
2. Powder sealed packaging, easy to transport, easy to store, long shelf life
3. Telephone anti-counterfeiting inquiry of original special reagents to ensure measurement accuracy
4. Quantitative reagent packaging, users do not need to weigh again, and the preparation method is simple
LH-D/E configuration method
Take LH-DE100 as an example:
1. Add all LH-D-100 reagents to a beaker, add 75mL of distilled water and stir continuously, add 5mL of analytical pure sulfuric acid during stirring, and bottle and seal after the reagent is completely dissolved.
2. Add all LH-E-100 reagents to a beaker, slowly add 500mL of analytical pure sulfuric acid several times while stirring continuously, and bottle and seal after stirring continuously until the reagent is completely dissolved.
COD liquid consumables
1, LH-COD-YD/E series dish colorimetry
2, LH-COD-YK series tube colorimetry
Features
1. Directly measure and use, greatly reducing reagent pretreatment and preparation time, quickly responding to experimental needs, and improving detection efficiency.
2. Adopting advanced production technology, strictly managing quality level, with good reproducibility, effectively reducing human errors.
3. No complicated configuration work is required, just add it to the water sample according to regulations to detect the value according to the process.
4. Effectively reduce the chance of experimental personnel contacting chemical hazardous substances, ensure the health of personnel, and at the same time, the amount of prefabricated reagents is smaller and the output of waste liquid is less.
COD prefabricated consumables(COD Vials)
LH-COD-YZ series
Features
1. Multiple range selection: The range is from 3-150mg/L, 20-1500mg/L, 200-15000mg/l, and users can choose according to different needs.
2. Reliable quality: Strict internal production and product quality control ensure the quality and stability of reagents.
3. Easy operation: No need to prepare reagents by yourself, saving time and improving safety. The operation is simple and easy to learn, and the illustrated operation guide is easy to master.
4. Time-saving and efficient: The digestion time is only 20 minutes. The entire test process includes steps such as water sample digestion and colorimetric determination. The detection time is short, which greatly improves the test efficiency.
5. Reduce costs: The detection cost is lower than similar products on the market, especially when used on a large scale, the cost advantage is more obvious.
6. Reduce environmental impact: The secondary pollution to the environment is small, and the sealed reagent tube can prevent harmful substances from splashing and improve the accuracy of measurement, ensuring the safety of the digestion process.
7. Improve safety: Avoid direct contact with chemicals, reduce the danger of chemicals, and are very friendly to experimenters and operation processes.
8. Reduce the use of chemicals: Prefabricated reagents complete the weighing, dissolution, mixing, and packaging processes in the factory in advance, and are directly used for sample testing, thereby reducing the use of chemicals.
9. Replace other brands of reagents: Lianhua’s COD prefabricated reagents can replace other brands of reagents, with higher cost-effectiveness and stable supply, without worrying about international situations or product price fluctuations
These advantages make COD prefabricated reagents widely used in laboratory and on-site water quality testing, especially in the investigation of sudden water pollution accidents that require a large amount of water quality data, and can quickly obtain a large amount of real-time water quality data.
