Digital refractometers with automation DR6000-TF

Maximum efficiency with automation

The DR6000-TF models with flow-through cell enable fully automatic operation in combination with drying unit, peristaltic pump and autosampler. There are four model variants available for the different requirements for accuracy, resolution and measuring range, whereby the same operation and functionality can be accessed.

• For continuous measurements or series of measurements with high sample volumes
• For low-viscous to slightly viscous samples
• With highly accurate internal Peltier temperature control
• Preinstalled and freely definable scales with conversions based on tables or formulas
• Chemical-resistant materials such as measurement prism made of sapphire, measuring tray made of stainless steel
• Also chemical resistant materials for the tubing and flow-through cell
• Control with and without external software possible
• Intuitive operation via state-of-the-art touchscreen display
• Complete data recording and backup including audit trail
• Flexible data export and simple data import with parameter processing via XML interface also possible
• Flexible and method depending cleaning procedures adjustable
• Compliance with global standards and norms

Typical applications

The DR6000-TF models are the ideal solution for manufacturers of flavors, fragrances and essential oils, as well as for the pharmaceutical and beverage industries.

• Routine analysis with high sample throughput
• Quality control of raw materials and auxiliary materials
• Monitoring of the production of semi-finished products and end products
• Quality and purity control of raw materials and end products
• Determination of the sugar concentration in juices and alcohol-free beverages
• Determination of the alcohol or extract content in beer, spices, wine or spirits

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.

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.
