---|---|
The user fills the sample chamber with 0.1 – 150 ml of sample, defines the sample in a simple dialog box, selects the desired experiment protocol, and clicks on “RUN”. When the measurement is complete, the user empties the sample, and then rinses the system with water or suitable cleaning solution. For Zeta potential measurements sample volume can be as little as 0.1 ml. For Particle Sizing measurements, sample volume can be as little as 3 mL for model DT-110, or DT-1210 with disposable cell. |
Automatic Titration with 1 or 2 burettes; pH / Temperature measurement; Conductivity measurement, aqueous and non-aqueous; Circulating pump for very viscous samples; Ports for remote “on-line” measurements; Rheology longitudinal; Temperature heating control; Disposable sample cell with sample volume <5 mL. |
