Solid / Thin Film Surface Zeta Potential Meter

Zeta potential refers to the potential of the shear plane and is an important indicator to characterize the stability of colloidal dispersions. Zeta potential is the electric potential difference between the surface of a solid or thin film and the surrounding liquid. The solid / thin film surface ZETA potential analyzer is an instrument used to measure the ZETA potential of solid surfaces or thin films. This instrument is commonly used in material science and colloid chemistry to study the surface charge of particles, the stability of colloidal dispersions, and the interaction between particles and surfaces in various applications such as coatings, adhesives, and biomedical devices.

Sample Requirements

• The size of the sample should be a rectangle of 10 × 20 mm and the thickness should not exceed 3 mm, and two pieces should be provided.
• If you need to test the zeta potential at different pH, the pH can be set in the range of 3 - 10.
• The sample must be able to withstand the impact pressure of 300 mbar.

Application

• Research objects: materials such as fibers, films, powders, particles, solid metal or non-metal sheets.
• Main purposes: measure the surface charge of materials, understand the charge status on the surface of materials, and study the surface properties of materials.

FAQ

Q. What are the requirements for sending samples for solid zeta potential test?

A. The sample needs to be able to withstand the impact pressure of 300 mbar, and two samples are required for one test, and a liquid environment needs to be formed on the surface (for example, fabrics will absorb buffer and cannot be tested).
