Density meter DS7800 for semi-automatic sample supply

High efficiency and special suitability for hazardous substances

In case of low-viscous to slightly viscous samples, it is possible to perform a semi-automatic sample supply and cleaning of the U-tube oscillator using a peristaltic pump. This means higher efficiency and more safety if aggressive or harmful substances are analyzed. It also improves the reproducibility of the measurement results.

• Drying unit and peristaltic pump with high chemical resistance

• Intuitive operation via touch-screen display

• Easy, menu-driven adjustment

• Pre-defined scales such as density, relative density, brix, alcohol and sulfuric acid concentration

• Compliance with GMP/GLP, 21 CFR Part 11, pharmacopoeias (USP, BP, JP, Ph. Eur.), FDA, ISO, HACCP, OIML, ASTM, ICUMSA, NIST

Typical applications

A comprehensive quality assurance covering the entire production process is a must in any industrial sector. Density measurements are frequently used for this purpose, especially in the pharmaceutical, chemical, petrochemical as well as the food and beverage industry. They allow the manufacturer to analyze raw materials, semi-finished and finished products as well as the manufacturing steps in terms of a number of factors.

Density can be used to identify substances, to determine their quality or purity and to measure their concentration in binary or quasi-binary mixtures. Substance conversions and reaction dynamics can also be inferred from it. In combination with other methods such as refractometry that measures the refractive index of substances, the density measurement allows you to make precise statements about the quality of each step of the production process.

Density meters based on the oscillating U-tube method are characterized by high ease of use and are therefore used in particular for continuous density measurement and for rapid routine measurements with larger numbers of samples in laboratories.
