For more than thirty years, Tintometer in Dortmund has been manufacturing reagents for water testing and marketing these reagents around the world under the brand name Lovibond.
For decades, the Tintometer® Group has been known as a producer of reagents for water analysis, which are supplied under the brand name Lovibond®. The wide range of applications requires different types of reagents. Also, users tend to have personal preferences as to which dosage system to use. Our broad product range covers blistered tablet reagents, powder reagents packed in aluminium foil and precise dosing liquid reagents in dropper bottles. With all our reagents, we strive to keep the formulations as environmentally friendly as possible. Hazardous substances are – whenever possible – replaced by harmless and functionally identical substitutes.
Where the required chemistry of the detection method makes the use of these substances absolutely necessary, the concentration levels are lowered to the minimum rate, without compromising the accuracy of the analysis results.
For example, our reagents for Pool & Spa water testing are free from boric acid, which is still frequently being used as an additive in the indus- try. The European Union (EU) has classified boric acid as a dangerous substance.
The Lovibond® DPD No. 1 tablets are not only 100% free from boric acid, they also guarantee compliance with the buffering effect required by the standard. This characteristic makes the tablet a leader in its field.
Our test tablets are manufactured in Germany under tightly controlled conditions on most modern machinery. Maintaining the highest quality standards permits Tintometer to guarantee our tablet reagents for a minimum of 5 years, and some for as long as 10 years. We can make this promise because each tablet is hermetically sealed within an individual aluminium foil pocket, protecting against challenging envi- ronmental conditions. This packaging keeps each tablet in perfect condition, right up until the time it is needed by the user.
Test tablets remain the most consistent and reliable reagent format available, consistently outperforming other reagent formats, and delivering maximum accuracy for the user.
The aluminium foil blister packaging brings added convenience to the tradition of protection achieved in the Lovibond® long established tablet production technology.
With the blister strip, the user just pushes the tablet through the protective foil, straight into the sample. Simple, time-saving and practical.
This type of packaging, long established in pharmaceutical applications, combines all the advantages of protective foil, with convenience for the user.
There are no safety risks if the tablets are used in line with the instructions supplied.
Safety data sheets are available for all reagents.

VARIO Powder Packs
The fast and easy use of VARIO Powder Packs has made them extremely popular for water testing applications in many countries throughout the world.The Lovibond Powder Pack programme provides more experienced users with a real alternative to existing measurement systems. The Vario Powder Packs are produced to the same high quality standards that have made Tintometer’s tablet reagents so successful for several decades. Parameters from aluminium and chlorine through to sulphate are just some of the well-known tests that are included in the VARIO Powder Pack range. Their chemical properties is suitable also for use with Hach® (Disclaimer) devices.

Lovibond tube tests enable the user to easily perform highly sensitive and precise water testing.When using tube tests measurement is considerably faster and easier, particularly in the case of standard and serial tests. The tube tests contain a precisely measured amount of reagent, thereby avoiding the presence of superfluous chemicals and optimising test sa-fety. Up to six different measuring ranges are available for the various tests. The tubes are made of special optical glass with a 16 mm in diameter. They are supplied in a storage and dispatch box together with the digestion or auxiliary reagents. This packaging unit contains 24 or 25 reaction vials and up to 2 zero vials for pho-tometer system calibration.
As a rule, liquid reagents do not consist of a single preparation but comprise several components that need to be added to the sample in a certain order. As both the size and the number of drops have a decisive effect on the resultant colour complex, the reagents need to be added with a high degree of precision. The useful life of liquid reagents is reduced by temporary contact with oxygen in the air when the bottle is opened as well as by unsuitable sto-rage environments (presence of sunlight or high temperatures). Provided that the bottles are stored within the temperature range +6°C to +10°C, the Lovibond DPD and Phenol Red solutions can be used for a period of one year from the production date.
Membrane filter set
For use when preparing samples for photometric measurements
- removes turbid materials from samples
- differentiates between dissolved and total substances
- 0.45 μm mesh meets the requirements of the official German unitary procedure for water testing
To prevent the effects of light scatter, it must be ensured that all turbid materials are removed from the sample before photometric measurements
are carried out. This can be achieved with the Lovibond® membrane filter set.
Where certain methods are employed (e.g., iron, manganese, CSB, etc.) a membrane filter set must be used to differentiate samples in terms of dissol- ved and total substances. The filter mesh size of 0.45 μm is in accordance with the official German unitary procedure for water testing.
Order code: 36 61 50
(covers 25 x 0.45 μm membrane filters and two 20 ml syringes)
