Characterizing proteins, nanoparticles, & polymers confronts users with a difficult choice of instrumentation. Brookhaven Instruments makes that choice easier with its highly configurable NanoBrook series of products.
The NanoBrook Series size and zeta potential analyzers incorporate all you need for fast, routine, sub-micron measurements of size and zeta potential. Based on the principles of Dynamic Light Scattering (DLS) for particle sizing and distribution, and based on doppler velocimetry (electrophoretic light scattering or ELS) for zeta potential measurement, most measurements only take a minute or two. The instrument also includes Phase Analysis Light Scattering (PALS) measurements for samples with low mobilities.
With the NanoBrook Omni, measure samples in nearly every possible suspension environment from high salts such as PBS and sea water to organic solvents and aqueous solutions. Particle and protein sizing, with the highest sensitivity, utilize three measurement angles for truly unbiased measurement results.
Spectra Research Corporation (SRC) offers a range of innovative high-quality scientific products and laboratory services to industrial and scientific markets throughout Canada.
