K7135, ABBE Refractometer

Uses:
Projection Abbe Refractometer is a kind of instrument which can be used to determine the refractive index nd and the mean dispersion nF - nC for the transparent or semitransparent liquid or solid (mainly used to determine the transparent liquid). 
With the help of thermostat, this instrument may be used to determine the refractive index nd for the substance within the temp. range from OoC to 50oC The refractive index & the mean dispersion are important optical constants; with which the optical property of purity, concentration and dispersion power, etc. can be determined for a certain substance. Therefore, this instrument has been used widely; it is an indispensable common one used in the industries of chemicals, grease, pharmacy, painting, food processing. sugaring, etc. by relevant factories, colleges, and scientific research institutes.
