Ultra Uniform Gold Nanoparticle Number Standard

Ultra Uniform materials are our most highly-monodispersed particles. Ideal for use as size standards or applications requiring a tight size distribution. Our Ultra Uniform Particle Number Standards provide additional characterization and careful formulation for applications that require a known particle number concentration.
