These digital density meters for fully automatic sample supply work with the proven oscillating U-tube technology. These density meters are ideal for working environments involving a high sample throughput that require fully automated handling of the entire process, from sample supply to cleaning and drying. Both the AS80 or AS90 autosamplers in combination with the DS7070 peristaltic pump are included in the set, thus enabling the automated measurement of up to 89 samples. The minimum sample volume supply of the oscillating U-tube is less than 1 ml. The internal Peltier temperature control ensures a fast and stable sample temperature. Whether density, relative density, Brix, alcohol, sulphuric acid concentration or other user-configured scales, the configuration options are virtually unlimited. Due to the chemical-resistant sample-carrying parts made of borosilicate glass and PTFE, these instruments are suitable for low to slightly viscous, aggressive samples. They are used in various branches of the pharmaceutical, chemical, petrochemical, and food and beverage industries. They can be used to determine quality or purity and to measure concentration in binary mixtures.
