iCheck Carotene

iCheck Carotene measures total carotenoids in food and biological fluids

iCheck™ Carotene is a state-of-the–art and the first of its kind portable photometer. It determines total carotenoid concentration in food and biological fluids. iCheck™ Carotene measures the color reaction in the test vial and calculates the carotene content in mg/L.
