The models are the ideal solution for the pharmaceutical, chemical, food and beverage industries, flavors, fragrance and essential oil, petrochemical, metalworking and automotive industries, as well as hospitals, pharmacies and exam offices.
All samples are measurable
From bright to dark, from basic to acidic, from a low to a high viscosity – for our refractometers almost all samples are measurable. A high-quality optics, intelligent evaluation logarithms and a powerful LED enable the measurement of particularly challenging samples. These include z. For example, non-homogeneous samples such as fruit juices containing pulp, opaque samples such as heavy oils or emulsions that are common in cosmetics. Aggressive acids and bases can be easily measured using a chemical-resistant stainless steel measuring tray and a sapphire prism.
In order to serve the existing variety of samples and the wide range of applications, we offer a wide range of different refractometers. For the selection of the suitable refractometer, it is helpful to define the required measuring range.
In the following table we have compiled an overview of typical samples from our customers and sorted them by refractive index. Most samples were measured at standard measurement conditions (20 ° C, λ = 589 nm), deviations are indicated. The measurements given are not specifications.
Conformity with national and international standards
Refractometers are also designed and used in accordance with standards. Standards in refractometry regulate, under the aspect of “best practice”, the environmental conditions and sample preparation as well as measurement tolerances, properties and equipment features of a device or certificates of calibration equipment and testing instruments. Whoever uses refractometers according to normative specifications can guarantee that measurements are correct and work according to reproducible procedures.
In order to make it easier for you to choose the right refractometer for your application, you will find for free download an overview of all standards and guidelines known to us in which refractometry is referred to.
