Stabino

The Stabino® is an efficient zeta potential and stability analysis system for colloids and dispersions.

The system is designed for rapid multi-parameter reading: zeta potential, streaming potential, titrations (pH and polyelectrolyte), conductivity, temperature and can be connected to a NANO-flex® 180° DLS particle sizing system for simultaneous size distribution measurement.

Analytik delivers zeta potential/stability/nanoparticle size analysers to the UK and Ireland from Particle Metrix.

We will be happy to work together with you on a solution with the full support of the Particle Metrix team. Visit our contact page, request a quote, or call us on +44 (0)1954 232 776.

Product Description

Zeta potential analysis with the Particle Metrix Stabino

The Stabino® is an efficient zeta potential analysis and stability analyser system for colloids and dispersions.

The system is designed for rapid multi-parameter reading: zeta potential, streaming potential, titrations (pH and polyelectrolyte), conductivity, temperature and can be connected to a NANO-flex® 180° DLS particle sizing system for simultaneous size distribution measurement.

Method

The “heart” of the Stabino® is a cylindrical PTFE chamber with an oscillating piston, both carrying only very little anionic charge at the surface.

The cylinder contains 1ml and 10ml sample respectively. The addition of titrands is controlled via two incorporated precision titration pumps delivering titrand solution from one or the other reservoir.  A fraction of the particles in the cell is immobilised at the surface of the wall. Therefore, with the piston movement Dv, the mobile cloud of the double layer of the immobilised particles is pushed up and down. That oscillating ion cloud produces an alternating voltage SP = streaming potential at the two electrodes. It is proportional to the zeta potential of the particles.

The Particle Interface Potential, like the streaming potential measured in Stabino®, represents the degree of electrostatic repulsion between particles and reacts to pH, conductivity and the poly-electrolyte surrounding, respectively. Any or all of these parameters can cause a material system to shift. The titration result is characteristic for the sample in a certain chemical environment. A charge titration with the Stabino® specifies which parameters require special attention.

Close to reality Multi-Parameter Particle Charge Mapping (3D – Plot)

The intuitive tablet PC controlled automatic titration of the Stabino® opens the way to particle charge finger-printing of colloids and dispersions. The isoelectric point is reached quickly, gathering information on charge density and stable zones, whilst pH, conductivity and temperature are measured simultaneously.
