The Rudolph Research J257 Wide Range Refractometer was developed by working together with laboratory refractometer users from the polymer, petroleum, petrochemical, pharmaceutical and essential oil ...

Refractometers are versatile in their design and use, and are able to provide results as refractive indices, or in other cases, as direct measurements of parameters such as soluble solids, sugar ...

Refractometer is precision optical instrument that operates on the principle- as the concentration or density of a solution increases, its refractive index changes proportionately. The refractive ...

Anton Paar’s Abbemat Pharma refractometers are the ideal solution for laboratories in the pharmaceutical industry, delivering precise refractive index (RI) measurements while ensuring full ...

THE accompanying diagram shows the essential parts of a refractometer using the principle of phase contrast, which is new for this class of instrument. It gives relative measurements, like most of the ...
