Rudolph Research

J 457 Series Digital Refractometer with Temperature Control (10-110 °C)

Rudolph refractometers provide excellent measurement of refractive indices and concentrations of liquid, gel and fluid derivatives used in all sectors, particularly in the pharmaceutical, food, cosmetic and petrochemical industries. It offers the possibility of easy model selection according to sensitivity, temperature range and methods to be worked.

The Main Sectors

  • Universities (Research Laboratories)
  • Food industry (sugar industry, olive oil, honey and fruit juice producers. Purity determination of water-soluble dry matter determination)
  • Chemical industry (determination of refractive index and refractive index)
  • Pharmaceutical industry (quality control of raw materials and final products)
  • Cosmetic industry (determination of the concentration and the amount of the substance)
  • Oil industry (oil ratios , to measure concentrations)
  • Agriculture Industry (determination of the amount of solid material in liquid material)
