Concentrated suspension of 1.0 µm solid latex microspheres that can be excited by a blue light source. A dilution of this suspension serves as a reference standard for laser alignment and focusing of flow cytometers equipped with a 488 nm laser. A diluted suspension of Calibration Beads 1.0 µm can also be used for quality control with standard settings and the analysis of small particles such as micro-organisms.

Reagent component:

• 1 mL Calibration Beads 1.0 µm Concentrate
