Laboratory Equipment for analyzing Zeta Potential, Particle Size and Molecular Size.
Zetasizer Nano - The Ultimate Versatile System
The Malvern Zetasizer range provides both exceptionally high performance and entry level systems that incorporate combinations of a particle size analyzer, zeta potential analyzer, molecular weight analyzer, protein mobility and microrheology measurements. Particles and molecules from less than a nanometer in size to several microns can be analyzed by a range of variants to suit your applications and budget.
The systems measure size and microrheology using dynamic light scattering, zeta potential and electrophoretic mobility using electrophoretic light scattering, and molecular weight using static light scattering. In addition the system can be used in a flow configuration to connect to a GPC / SEC system for use as a chromatography size detector.
Zetasizer APS - DLS Plate Sampling Technology for Unparalleled Data Quality & Automation
The Zetasizer APS is a robust, simple to operate, Dynamic Light Scattering automated plate sampler that automates the measurement of samples in industry standard 96- or 384-well plates.
The Zetasizer APS transfers 20µL sample from each well to a precision quartz flow cell for measurement. The cell environment is optimized for precision temperature control and optical clarity to ensure the most accurate and precise results. This means that any industry standard disposable or reusable plate can be used without concern for transparency or scratches on the plate that would affect the result.
Zetasizer µV - Dedicated to Proteins
Dual Integrated Light Scattering system dedicated to protein characterization. Use as a chromatography detector with any GPC/SEC system to give absolute size and absolute molecular weight. Use in cuvette mode for the detection of large aggregates.
Dynamic Light Scattering is used to measure particle and molecule size. This technique measures the diffusion of protein molecules moving under Brownian motion, and converts this to size and a size distribution using the Stokes-Einstein relationship.
Static Light Scattering is used to determine molecular weight. When used as a detector, the light scattering intensity in combination with the signal from a concentration detector enables the absolute molecular weight to be calculated.
