Clinical Refractometer 300005

This portable refractometer works in ambient light with no battery or other power source. A refractometer measures the extent to which light is bent (refracted) through a liquid sample. Commonly used to help identify or confirm the identity of a sample, asses the purity of a sample, or determine the concentration of a solute in a solution. Can be used in labs, on production lines, in the field or anywhere. Simply place a drop or two of a sample on the prism and read the results immediately. With reasonable care, the reliability, precision, and optical performance will last forever. 

Comes complete with: 

• Rubber coated hand grip and construction, which insulate the test solution from inaccuracies caused by the user's body heat. 
• Covered eye piece and bright, clearly defined scale, with large easy to read measurements.
• All the accessories for immediate use, including tools and solutions, full instructions, transfer pipettes and protective case. 

Measures urine specific gravity, or gives the refractive index in seconds.
