Nano Particle Size, Molecular Weight and Zeta Potential DLS Analyzer

Outstanding performance, sensitivity, compact bench-top footprint, and intuitive software make the NanoPlus series of products the preferred choice in determining particle size and zeta potential on a wide variety of materials.

Highly Accurate Zeta Potential Measurements of Concentrated Solutions
Patented FST technology utilizes a transparent electrode to minimize path length and reduce multiple scattering effects. This technology permits accurate zeta potential measurement in a wide concentration range of 0.00001 to 40% (w/v) unique to the NanoPlus, eliminating the need to dilute samples.

True Determination of Electrophoretic Mobility
The NanoPlus negates the effects of electroosmosis by measuring zeta potential at five different locations within the cell. As a result, the instrument can calculate and accurately measure true electrophoretic mobility, resulting in a highly accurate determination of zeta potential. This also provides the ability to determine multi-modal distributions of zeta potential mixtures.

Broad Particle Sizing Range with Increased Sensitivity
The Nanoplus has a dynamic sizing range of 0.1 nm to 12.30 µm in a concentration range of up to 40% w/v, and a sensitivity for molecular weight to as low as 250 Da. Dual correlators, log-scale for larger particles prone to time decay and linear scale for small particles, provide high sensitivity measurements in multicomponent samples.

Wide Range of Measuring Cells
The NanoPlus features a wide range of measuring cells available for both zeta and nano particle size measurements. Included is a unique solid sample cell for zeta potential measurement of coated surfaces, films or treated glass slides.
