Revolutionize DLS. The DynaPro Plate Reader offers dynamic light scattering (DLS) and static light scattering (SLS) measurements of the size, molecular weight and interactions of proteins, nanoparticles and other macromolecules in situ in industry-standard microwell plates. No liquid handling occurs after dispensing into the plates, to maximize throughput and minimize sample carryover.

Theory of Raman Scattering. When considering Raman scattering, we can think about the physics in one of two ways: the classical wave interpretation or the quantum particle interpretation.

Static light scattering is a technique in physical chemistry that measures the intensity of the scattered light to obtain the average molecular weight M w of a macromolecule like a polymer or a protein in solution. Measurement of the scattering intensity at many angles allows calculation of the root mean square radius, also called the radius of gyration R g.
