Protein Handheld Refractometer

I.Introduction:Handheld Refractometer
The refractometer is an instrument that measures the concentration of an aqueous solution by measuring its refractive index. All water based solution can make light bend. The bending of light increases at a rate proportional to the increasing solution concentration.  The handheld refractometer is a precise optical instrument. It"s characterized by small volume, light-weighted, graceful in shape and easy to operate. Therefore it can be used from all sides.
