Serum Protein Refractometer 

Serum Protein Refractometer is a high-precision optical instrument designed by the principle of refraction. It is small and beautiful, easy to use, and LCD large-screen digital display. As long as a drop of sample solution is placed on the prism, the measured value will be displayed quickly, which avoids the subjective error numerical interpretation.

Serum Protein Refractometer Application:

Serum Protein Refractometer can accurately and rapidly measure the concentration level of physiological fluid, serum albumin and refractive index of urine.

Serum Protein Refractometer is an instrument that can quickly and accurately measure the amount of serum protein. When using this instrument for testing, a drop of liquid sample is enough. It can be used for rapid liver function testing. It is indispensable equipment in hospital laboratories and can also be used as a home diagnostic instrument.

Serum Protein Refractometer is simple in structure, easy to operate and carry, and is an indispensable testing equipment for hospitals, scientific research institutions and veterinary industry.

Serum Protein Refractometer Measuring Method:

Drip 2 to 3 Samples to the surface of prism refractometer -press “START” button, measured value and the temperature will be displayed within 2 seconds.

Serum Protein Refractometer Maintenance and Preservation:

1. Please clean and wash the sample plate with distilled water and dry it with soft cleaning cloth or paper towel after finishing the measuring one kind sample.

2. Never left the remains and residuals of samples in the sample plate for long time.

3. After finishing measurements of the corrosive liquid, please clean the sample plate as quick as possible to avoid the irreparable damage of the prism and metal surface of the plate.

4. Please use soft cleaning cloth or paper towel to clean the sample plate to avoid scribing the prism’s glass.

5. When the dropper and dust-free cloth are not used, please clean it with clean water and put it in the packing box after drying.

6. If no using the instrument for a long time, please remove the battery, and preserved in a cool and dry environment.
