Product Overview

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 (> 2 um) have a CV (coefficient of variation) of 1% to 5%. Smaller beads (<=2 um) have a CV of 5% to 15%. We produce both white beads and fluorescent beads for use as size standards.

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

Size Standard Microspheres Nano Kit: 0.2 um, 0.4 um, 0.5 um, 0.8 um, 1.0 um

Size Standard Microspheres Micro Kit: 1 um, 2.5 um, 5 um, 7 um, 10 um

Fluorescent Size Standard Kit: 2.5 um, 5 um, 7 um, 10 um

For our fluorescent beads, detection can be observed with a 488 nm laser at FL1 (Em525/50), FL2(Em710/50), and FL3(Em610/20).

Fluorescent Size Standards (NIST traceable)

Fluorescent Size Standard are NIST traceable size particles, doped with appropriate fluorescent dye.

Magsphere Inc.'s Fluorescent Size Standard Beads, FSS Beads, are suspended at 10mL and 5mL at 2% solids. Sizes are available at 2.5Ám, 5Ám, 7Ám, and 10Ám. Fluorescent Size Standard Kits are also available at 5mL at each size. A blank calibration beads, with similar size, will be included to determine threshold limits. Product will be shipped within 10% of the diameter you selected.

Fluorescent Size Standard Polystyrene microspheres can be used in size analyzer, flow cytometers, and microscope observation.
