For applications requiring the highest uniformity in size and shape, our Ultra Uniform Gold Nanospheres have a nearly perfect spherical shape, smooth surfaces, and impressively narrow size distributions (CV < 5%).
Why Choose Ultra Uniform?
Ultra narrow size distribution & aggregation free
Our Ultra Uniform particles have the lowest coefficients of variation available anywhere. They are used as particle size and concentration standards, electron microscopy standards, and for applications where tight tolerances on the particle size, shape, mass, or volume are required.
