Light Scattering User Meetings

Wyatt's regional user meetings are a great opportunity to meet and interact with other scientists who utilize Wyatt light scattering instruments. Learn how your colleagues approach biophysical characterization, pick up some tips and tricks on method development, and spend some quality time with Wyatt staff. Registration is free for this event.

Light Scattering Workshop

New to light scattering? Wondering how light scattering works and how it’s applied? Wyatt's regional light scattering workshops are a wonderful opportunity to learn the “basics” of light scattering and see live demonstrations of Wyatt instruments. Learn the limits and capabilities of light scattering and how these methods can complement your existing suite of tools. Registration is free for this event.
