Answer 1

A double beam optical instrument is a modern optical device that permits high level of automation and offer same or even better level of detection as compared to single beam system. A medical instrument that operates in this principle is double beam spectrophotometer. It finds greater application in clinical laboratories where it is used for many application such as kinetics, spectrum scanning and DNA/protein testing. It is also used to measure growth of bacterial culture. It offers a simple and rapid analysis that requires only minimal sample preparation and use. New advancement offer both portable and durable options.
