DS7800-2 density meter for manual sample supply Set 2
DS7800-2 density meter for manual sample supply Set 2
The right decision for low sample volumes
For manual sample delivery via syringe, we offer two different density meter sets: For low sample volumes and high viscosity samples, we recommend Set 1 and for highly viscous and aggressive samples Set 2. While the sample is added, you can check for air bubbles by looking through the inspection glass. A suitable medium is injected for the cleaning until all sample residues have been dissolved and removed. The drying unit will then remove all liquid residues.
- Sample supply and cleaning via syringe
- 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, pharmakopoeias (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 analyse 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.
