50nm Ultra Uniform Gold Nanoparticle Number Standard Concentration:1e8 Particles/ml In Aqueous 1 mm Sodium Citrate, Each Of 25ml

Details:

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. Peg-carboxyl is covalently bound to the metal surface. Size- 50 nm
