Lactoscan milk analyser is a straightforward, accurate, and trustworthy tool for quantifying milk ingredients. It can be used to determine the amount of fat, protein, lactose, and total solids in milk and is based on the selective photometry principle. One hand operation is possible due to the instrument's small size and light weight. It works with either disposable cuvettes or glass bottles and includes a large LCD display for easy reading of the results. Lactoscan milk analyser is powered by four AA batteries.
