Kruess Optronic DR6000 series Digital Laboratory Refractometers

Versatile and Powerful

The Kruess DR6000 series Digital Refractometers with an intuitive touchscreen presents a clear overview of all data and functions and the integrated SQL database stores all data and allows external access via a network or standalone PC.

The refractive index is a parameter in quantitative or qualitative analysis and quality assurance. Degrees of polymerisation can also often be monitored frequently, quickly and cost-efficiently without turbidity or the colour of the sample affecting measurement precision. There is no longer any elaborate preparation of samples necessary. The sample is simply placed on the measuring prism and the measurement process is started.

The flat stainless steel plate is easy to clean and is highly resistant to aggressive substances. As the refractive index depends on the temperature of the sample, the refractometer should be tempered. The DR6000 series is thus available with integrated electronic temperature control by means of a Peltier element. This type of temperature control is faster and more reliable than water bath thermostats.

For continuous measurements or series of measurements with many samples and high volumes of samples, flow cells are available. A sample can thus displace the previous one, nonetheless achieving an accurate measurement result without cleaning the measuring prism after every measurement.
