Fully automatic sample supply

Density meters for fully automatic sample supply

Set 4 / Set 5

Density meter DS7800 with autosampler for fully automatic sample supply

Fully automatic execution of the entire measuring process

Working environments involving a high sample throughput require flexible, powerful and robust solutions for a fully automatic execution of the entire process from the sample supply to the cleaning and drying. Our AS80 and AS90 autosamplers meet these high requirements. Together with the peristaltic pump DS7070, they allow for an unsupervised measurement of up to 89 samples. For a high sample volume of aggressive samples we recommend Set 5.

• Suitable for low-viscous to slightly viscous and aggressive samples

• Fully automatic sample supply and cleaning

• Fully automatic drying

• Individual measurement methods and cleaning procedures as well as sampler templates possible

• Easy and fast to install autosampler

• 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.
