Samples and their refractive index (nD)

Almost all samples are measurable. To be able to serve the existing variety of samples and the wide range of applications, we offer a large assortment of different refractometers. For the selection of the suitable refractometer it is helpful to define the required measuring range. When purchasing a new refractometer, there is a real savings potential, because refractometers with a small measuring range are usually more cost-effective compared to instruments that cover the entire measuring range.

Please feel free to inform yourself: In our table we have compiled a comprehensive overview of measurement samples with the specific refractive index. Most samples were measured at standard measuring conditions (20°C, λ = 589 nm), deviations are indicated. The measured values given are not specifications.
