What type of Reagent should you choose?

General Guidelines:

  • For the most accurate results, tablet reagents are the best form of reagent. Lovibond® tablets have a guaranteed shelf life of 5 or 10 years. Each tablet is sealed in foil, eliminating the possibility of indicator aging. Tablets also have greater accuracy in terms of their manufacture – the amount of reagent contained in each tablet is extremely accurately dosed when compared with powder reagents. However, the disadvantage is that they need to be crushed with a rod before use. For example, DPD tablets.

  • Powder reagents are more convenient to use, as they do not require crushing. However, they are often less accurate than tablets and the packaging can also create more litter.

  • DPD Powder Pop Reagent Dispenser – this is ideal for bulk testing. Companies that do bulk tests (100 – 1000) find it reduces the need for opening individual packages and provides high reproducibility.

  • Liquid reagents are best to use when more complex mixes of reagents are to be used, eg.

  • Tube tests make measurement of more complex tests easier and more accurate, as the chemicals are already precisely mixed, eg COD (Chemical Oxygen Demand), Nitrates. However, they are expensive.

Which reagents do you need to test specific parameters?

For a list of available reagents, please see the attachment Lovibond® Reagents Table under the Downloads tab. It lists all Lovibond® reagents available for the different instruments.

There is also an attachment of the Applications suitable for the reagents, eg Waste water / effluent water / sea water.

If you need to perform a specific test and are not sure which reagents you need, please send us an email with the test you want to perform, the range or what type of water you are testing, which instrument you have and we will recommend a reagent.
