Automatic Dilution and Dosage System: DDS

The automatic dilution and dosage system automates the routine preparation of sample dilution at accurate weight/weight or weight/volume ratios. Manual sample dilution and dosage methods are time-consuming and error-prone. DDS performs gravimetric dilutions and dosages under continuous weight control by a digital laboratory balance. All calculations for determining the required weight of solvent for a given weight of sample (solid or liquid) are automatically performed by DDS.
