517711BT Combi-Pack: DPD No. 1 / DPD No. 3, 100 TABLETS EACH by AquaPhoenix

Test tablets are manufactured in Germany under tightly controlled conditions on the latest machinery. Maintaining the highest quality standards permits Tintometer GmbH to guarantee our reagent tablets 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 aluminum foil, protecting against challenging environmental 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.

Now we have improved even further on this highly successful format. To the tight quality control processes, integral to Lovibond®'s tablet manufacture, and the simple test procedures, we have added new blister packaging. Our new aluminum foil blister packaging brings added convenience to the tradition of protection achieved in Lovibond's long established tablet production technology.

With the new 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. Each tablet is contained within an individually formed foil cup, lined with the latest aluminum composite material, and guaranteeing product performance.

As a result of improved sealing efficiency, the blister pack has been reduced in size to 91× 34mm making them even more convenient for storage and shipping. 'BT' is added to the end of the code to identify the new style of packaging. There are no safety risks if the tablets are used in line with the instructions supplied. Safety data sheets are available for all reagents.
