iCheck Fluoro

iCheck Fluoro measures vitamin A in biological fluids and food

iCheck™ Fluoro is a state-of-the-art portable fluorometer. It determines vitamin A quantitatively in food and biological fluids. Using innovative technology it measures the fluorescence of vitamin A in the sample. The vitamin A concentration is displayed in μg RE/L (RE=retinol equivalent). It is used to measure vitamin A in vitamin premixes, sugar, flour, milk and biological fluids such as breast milk.
