The FREE System is an integrated analytical system
consisting of a photometer and a mini-centrifuge and a number of
tools (microipipettes, tips, tubes etc.), that is able to carry
out any chemical analyses based on the principles of spectrophotometry
(e. g. blood glucose, cholesterol, creatinine, transaminases etc)
and, particularly, the whole panel of oxidative stress tests.
