NANOTECHNOLOGY IN SAUDI ARABIA HAS EMERGED AS AN AREA OF SIGNIFICANT INTEREST, BOTH IN ACADEMIA AS WELL AS IN THE INDUSTRY. ZETASIZER ZS / ZETASIZER µV / ZETASIZER APS

Malvern Instruments—Zetasizer Malvern Instruments’ ZETASIZER Systems provide objective scientific measurements to help match experience to performance. By measuring fundamental parameters known to affect stability - such as zetapotential, particle size, pH and conductivity, investigators can identify, measure and vary the parameters that determine stability. Malvern instruments Zetasizer range uses light scattering techniques to measure hydrodynamic size, zeta potential and molecular weight of proteins and nanoparticles. Technology: - Unequalled sensitivity and versatility are achieved using the latest technology.  Patented NIBS optics improves sensitivity and size range / concentration range in the Zetasizer Nano S and ZS.  M3PALS is the leading technology for measurement of Zeta-potential.  Single-mode fibre, 50m W laser and focused optics enable measurements

of unrivalled quality of Proteins and other biomolecules. Applications: Colloids - Measure the size and zetapotential to optimize stability and shelf life and speed up formulation development. Automate pH titrations and measurements using the optional autotitrator. Nanoparticles - Measure size, polydispersity and zetapotential to optimize production processes. Proteins - Determine the presence of aggregates; screen for optimum crystallization conditions; and study oligomer formation in as little as 2µL of sample, requiring just nanograms of material.
