The highest quality Rainbow Calibration Particles


Number 1: Rainbow Calibration Particles, 6 peaks

Rainbow calibration particles, also known as rainbow beads, are a type of fluorescent microsphere used in flow cytometry for instrument calibration and quality control.

Rainbow Calibration Particles are used for calibrating flow cytometers. The mixture of particles features:
• 8 different fluorescent intensities
• Excitation by wavelengths ranging from 365–650 nm
• Particles 3.0–3.4 µm in size


Flow cytometry is a powerful analytical tool used to identify, count, and characterize cells or particles based on their size, shape, and other physical and chemical properties. To ensure that the flow cytometer is performing accurately and consistently, it needs to be calibrated with particles of known size and fluorescence intensity. Rainbow calibration particles are one such type of particle that is commonly used for this purpose.

Rainbow calibration particles consist of microspheres that are dyed with a series of fluorescent dyes, each of which emits light at a different wavelength. By combining multiple dyes within each bead, rainbow calibration particles can be used to create a unique spectral signature or "rainbow" that can be easily detected by the flow cytometer.

Why are these the best?!!

During calibration, rainbow calibration particles are run through the flow cytometer alongside the samples of interest. By analyzing the fluorescence emission of the rainbow calibration particles, the instrument can be calibrated for sensitivity, linearity, and resolution across a range of wavelengths. This helps to ensure that the instrument is functioning properly and that the data obtained from the samples is accurate and reliable.

Overall, rainbow calibration particles are an important tool in flow cytometry for quality control and calibration, allowing researchers to obtain accurate and precise data for a variety of applications in the life sciences.
