The Nano ZS, Z and ZS90 can all use the unique disposable zeta potential cell to ensure no cross contamination of samples.Īll systems are compatible with the MPT-2 autotitrator to enable trend measurements and sample preparation to be automated. analysis (Malvern Zetasizer so ware) using a Malvern Zetasizer.
#Malvern zetasizer weitz series
The Zetasizer Nano ZS is the pinnacle of the Malvern Zetasizer Nano series and can measure all three parameters with no performance compromises. According to Pine and Weitz (chapter 16 in Dynamic Light Scattering: The. Molecular Weight - An avalanche-photodiode detector and fibre detection optics give the sensitivity and syability required for absolute molecular weight measurement. The presence of multiple scattering during a DLS measurement will lead to. Zeta Potential - M3-PALS technology enables accurate measurements of zeta potential in aqueous and non-aqueous dispersions. The measurement was done in either steady state or dynamic (oscillatory. Neither the solvation of the ions nor the presence of charges on the spheres relies on the addition of charge-stabilizing agents. Rheological analysis The rheological properties of the toothpaste were ana-lyzed by using a rotational rheometer (Kinexus, Malvern, UK) equipped with cone and plate geometry (40 mm diameter, 4 cone angle). The presence and positive sign of these charges are confirmed through electrophoresis performed with a Malvern Zetasizer Nano ZS with a universal dip cell (ZEN1002). Particle Size - NIBS technology enables measurements of particles and molecules from 0.6nm to 6 microns. tering (DLS) using a Zetasizer Nano ZS System (Malvern, UK). The patented NIBS optics incorporated into the Nano Z and Nano ZS also allows measurements of samples with little or no dilution. The new technology incorporated in these systems provides unequalled sensitivity and versatility. The exosome markers CD63 and TSG101 were detected by western blotting. The size distribution of exosomes was determined using a Malvern Zetasizer Nano ZS90 (Malvern, UK), according to the manufacturer’s instructions. Malvern Zetasizer Nano ZS (Malvern Instruments Ltd., UK). The morphology of SW480-exo and SW620-exo cells was imaged by a transmission electron microscope (FEI Tecnai Spirit Bio-TWIN). The Zetasizer Nano series can measure a combination of three of the most important parameters for the colloid and polymer chemist - particle size, zeta potential and molecular weight.
