One versatile unit for the serum protein concentration, urine specific gravity, and refractive index. protein in g/IOOml Refractive Index Urine specific gravity Size & Weight ©Read the boundary line where the blue and white colors meet. Specifications Measurement Range Urine S.G. 1.000 to 1.050 Serum protein 0.0 to 12.0g/100ml Refractive Index 1.3330 to 1.3600 Minimum Scale Urine S.G. 0.001 Serum protein 0.2g/100ml Refractive Index 0.0005 About Scale This instrument has been designed to use the refractive index method for measuring total protein in serum. The protein scale has been prepared after extensive clinical analyses under taken by Dr. Matsumura, Professor of Bio chemistry at the Tokyo Women's Medical College. His scale is based on the results obtained from over 1400 cases. The scale is the most reliable one at present available. As the same as serum protein, there is a correlation between refractive index by a refractometer and urine specific gravity by a hydrometer. Urine specific gravity can be taken from refractive index. Measurement range of this unit is 1.000 to 1.050. All ATAGO refractometers are designed and manufactured in Japan. HACCP | GMPI GLP ATAGO products comply with HACCP, GMP. and GLP standards.
