Used MALVERN Zetasizer ZEN3600 #293648834 for sale

MALVERN Zetasizer ZEN3600 is a versatile particle counter designed to measure a range of characteristics of particles up to 600nm in diameter. The unit can detect the size distribution, zeta potential and molecular weight of a sample. Firstly, Zetasizer ZEN3600 is set up to measure particle size. The particle size measurement is done by a combination of dynamic light scattering (DLS) and static light scattering (SLS). With laser scattering optics, the device can measure the particle size and sample concentration in the range of 0.5 - 600 nanometers (nm). The particle size data is shown on a graph, in which the x-axis is the particle size and the y-axis is the count of the particles in the sample. The data obtained can then be used to measure the sample's zeta potential. This is measured using laser Doppler technology and is used to understand the sample's colloidal stability. Zeta potential values below -30 and above +30 indicate a strongly charged sample and has implications for particle deposition, aggregation and flocculation. Finally, MALVERN Zetasizer can also measure the molecular weight of a sample. It uses a technique known as multi-angle light scattering (MALS) to measure the sample's molecular weight on a molecular basis. The number and mass of the individual molecules in a sample can be determined, and the measurements are within 1% of the true molecular weight, thus providing accurate measurements in the range from 1 dalton to 2,000 kDa. To ensure accuracy, MALVERN Zetasizer ZEN3600 is calibrated with certified bead standards and is designed to be easy to use. An intuitive user interface is provided and allows easy access to the parameters and settings that define the measurement. The device is also easily configurable, allowing users to select the optimal set up for their specific samples. Zetasizer ZEN3600 is an ideal solution for a range of particle characterization applications. It provides reliable and accurate measurements for particle size and zeta potential as well as sample molecular weight in one convenient device.
