Aquakem 250

Thermo Scientific* Aquakem 250 Photometric Analyzer is a discrete, random access analyzer for a wide variety of water and environmental tests. 
The Aquakem 250 is an easy to use chemistry analyzer capable of random access or batch analysis and the use of multiple chemistries. Types of matrices analyzed include clean water, wastewater, soil/sludge digests, effluents and saline. The Aquakem system can be custom-programmed to meet individual needs in each laboratory. All method protocols are based to those recommended in the standard methods for the examination of water and wastewater in different countries and those published in the U.K. Blue Book.
