It works very well, we tested the results using Gesan Production reagents and they're accurate. The maintenance of the instrument is semi-automatic so it works without troubles for the operator because it's always properly set. I can confirm that Chem 300 plus is one of the best choices in my lab.

Chem 200 is easy to use and the interface is really user friendly and intuitive even if it has a lot of functions. I would recommend it to my colleagues.
