Mobius Dip Cell
The Mobius Dip Cell is a convenient alternative to the Mobius flow cell for manual measurements. 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 µL of solution under typical conditions. The Mobius Dip Cell is optimal for PALS measurements of nanoparticles, proteins and other macromolecules. It should 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.
All nanoparticles (unless DLS is required and Rh > 200 nm)
