ZetaStar Dip Cell
The ZetaStar Dip Cell is a low volume alternative for measuring zeta potential. As with the flow cell, the dip cell affords simultaneous mobility and size measurements in order to determine zeta potential or charge while monitoring potential degradation of the sample under an applied electric field. The dip cell requires only 65 ÂµL of solution under typical conditions. The dip cell is optimal for ELS measurements of nanoparticles, proteins, and other macromolecules. Using the dip cell also allows the user to collect simultaneous SLS & DLS or sequential SLS & ELS measurements through the Touch screen. The dip cell should only be used for low conductivity samples not requiring the Atlas pressurization module and is useful for quick testing before setting up automated, multi-sample methods. It cannot be used for DLS measurements if Rh > 200 nm.
