Applied Microspheres’ Zeta Potential Controls
consist of negatively charged polystyrene
particle suspensions that are designed for reproducible
zeta potential validation. A special
formulation ensures that the negative charge
is stronger than is the case with common
polystyrene suspensions. The suspension has
a negligible content of charged surfactant,
resulting in the reduction of background noise.
Applied Microspheres Zeta Potential Controls
are supplied in single use, 3 ml or 10 ml luer
lock syringes, packaged in boxes of 10 or 18
syringes. Shelf life is 18 months from date of
packaging. They can be stored at room temperature.
