Density Meters Manual Sample Feeding
These digital density meters for manual sample feeding work with proven oscillating tube technology. In these models, the sample supply of low- to high-viscosity samples is carried out via Luer syringe. During sample feeding, the viewing window is used to check whether the filling is bubble-free. The internal Peltier temperature control ensures a fast and stable sample temperature. Suitable solvents are injected for cleaning until all sample residues are dissolved and removed. With the help of the drying unit attached to the device, all liquid residues are removed from the oscillating tube. Thanks to the chemical-resistant sample-carrying parts made of borosilicate glass and PTFE, our density meters are suitable for almost all liquids, emulsions and pastes. The minimum sample volume of the transducer is less than 1 ml. Whether density, relative density, Brix, alcohol, sulfuric acid concentration or user-configured further scales, the possibilities of configuration are almost unlimited.
