Size Standards (NIST traceable)

Our NIST traceable size standards are used for calibration of instruments such as size analyzers, flow cytometers and microscopes. Our larger beads (>2µm) have a CV (coefficient of variation) of 1% to 5%. Smaller beads (<=2µm) have a CV of 5% to 15%. 

Magsphere now offers a variety of Size Standard Kits. We have a nano kit and a micro kit for plain microspheres. All kits contains 5mL of each size standard. Sizes are listed below.

Size Standard Microspheres Nano Kit (SDNANO): 0.2µm, 0.4µm, 0.5µm, 0.8µm, 1.0µm

Size Standard Microspheres Micro Kit (SDMICRO): 1µm, 2µm, 5µm, 7µm, 10µm
